What is immersion?

Immersion means consuming real Japanese: watching, reading, listening, so you build a natural feel for how the language works.

Rather than memorising rules from a textbook, you absorb patterns the same way you absorbed your first language as a child. This is based on the Input Hypothesis: the best way to acquire a language is through comprehensible input, content you can understand, even if you miss the details.

Input has to be comprehensible to work. If you understand nothing at all, it's hard to make progress. Aim for content where you can follow what's happening, even if you miss details.

Why not just use textbooks?

Textbooks teach you concepts, but they can't show you all the ways language is actually used. Japanese isn't a 1:1 translation of English. Many words and grammar points have nuances that simply don't exist in English.

The particles は and が are a classic example. People struggle with them for years studying from textbooks, because the difference only clicks through seeing them used in real sentences across many contexts. Immersion is how that happens.

You will understand almost nothing at first. This is completely normal. Progress feels slow for a long time, then suddenly accelerates. Just keep going.

Watch: what is input?

foundation

The goal: automaticity

Understanding Japanese without translating it in your head first.

In your native language, you don't consciously decode each word when someone speaks to you. You don't translate in your head. You just understand. That's automaticity and it's what immersion is building toward.

Early on, you'll be translating everything and looking things up constantly. That's fine and expected. Over time, sentences start clicking before you finish reading them. Eventually whole scenes flow without effort. The goal is to reach that point in Japanese.

Getting there takes hundreds or even thousands of hours of immersion. But it mostly means watching anime you enjoy, so it's not as daunting as it sounds.
foundation

Basics

Before immersing, you need a foundation. Work through Step 1 first, then move on. Steps 2-4 can be done at the same time.

Japanese has three writing systems
  • Hiragana (ひらがな) — the basic Japanese alphabet, used for grammar and everyday words
  • Katakana (カタカナ) — a second alphabet with the same sounds, used mainly for foreign words (コーヒー, kōhī)
  • Kanji (漢字) — characters borrowed from Chinese, each representing a concept (e.g. 山 = mountain, 水 = water); learned through words, not memorised individually
01
Kana
Hiragana & Katakana

Learn Hiragana then Katakana, one row at a time. Drill with kana.pro until you can read each set without hesitation. Use the Tofugu guides if you need mnemonics. There is also a video introduction to Hiragana and Katakana.

02
Grammar
One guide, start to finish

Pick one guide and read through it. Understand each point, then move on. Don't aim for perfection. Yokubi is recommended; Tae Kim and Japanese Ammo with Misa are solid alternatives.

03
Vocab & Kanji
Anki · 10–20 cards/day

Use Anki (a flashcard application for memorization) with the Kaishi 1.5k deck. Do 10–20 new cards a day. No need to study kanji in isolation — picking it up through vocab is enough.

04
Pitch Accent
10 min daily ear training

Japanese uses pitch (high/low) rather than stress accent. Below is a video explanation of what pitch accent is. Read the pitch accent primer to understand the basics, then train your ear with Kuuube's minimal pairs for 10 minutes daily.

Daily routine for this stage

Anki 10–20 new cards + reviews · 15–30 min
Grammar 2–3 sections from your chosen guide
Pitch 10 min minimal pairs daily
Stage goal: finish the grammar guide, reach ~1,000 known words, and pass minimal pairs. Once you're there, move on to immersion.
setup

Tool setup

For the purpose of this guide, we will be using anime. Here are a few tools that turn anime into an immersion environment. Follow the video below, then use the written steps alongside it.

Bunpro is a grammar SRS that drills grammar points in context, useful alongside immersion for N5 through N1. Browse the full grammar point list for free at bunpro.jp/grammar_points Alternatively, you can use the Dictionary of Japanese Grammar, which is more comprehensive.

What you're installing

  • ASBPlayer — attaches Japanese subtitle files to streaming video in your browser, including YouTube
  • Yomitan — hover over any Japanese word to get an instant dictionary pop-up
  • Jimaku — where you download Japanese subtitle files for anime
  • A streaming site — needs to let you disable built-in subtitles (Miruro, Anizone, Crunchyroll, Netflix all work)

Step-by-step

  1. 01 Install Yomitan first. Follow the setup guide at learnjapanese.moe/yomichan. It walks you through installing dictionaries too.
  2. 02 Install the ASBPlayer extension from the Chrome Web Store. Firefox users can grab it from GitHub.
  3. 03 Go to jimaku.cc, search for your anime, and download the subtitle file for the episode you want. Either .srt or .ass format works fine.
  4. 04 Go to your streaming site or YouTube, find your anime, and start playing it. Disable the site's built-in subtitles so they don't overlap.
  5. 05 Drag and drop the subtitle file on top of the video/anime in your streaming site. You will see a large ASBPlayer logo and the subtitles will appear.
  6. 06 Hover over any word in the subtitles with Yomitan to look it up. You're ready to immerse.
If subtitles are out of sync, press Ctrl + Shift + to push them forward, or Ctrl + Shift + to pull them back. Each press adjusts by 100ms.
YouTube works too. Open any YouTube video in your browser, load a subtitle file via ASBPlayer, and it will overlay the Japanese subs directly on the video; useful for J-drama clips, variety shows, and anything else on YouTube.

How to immerse

Think of each sentence as a small puzzle. Your job is to fit the pieces together, look things up when needed, use context when you can, and move on. Below is an example process for beginners to follow.

The process

  1. A sentence appears. Read it.
  2. Count how many things you don't know — words, grammar, kanji.
  3. 0–2 unknown things: look them up with Yomitan. Spend 30–60 seconds working out what the sentence means.
  4. 3 or more unknown things: skip it and move on. Don't force it.
  5. Whether you got it or not — move to the next sentence.
Skipping sentences isn't giving up. It's the correct use of the method. A sentence with too many unknowns won't stick even if you look everything up. Move on and come back to hard things naturally over time.

Watch: the process in action


How often to look things up

There's no single right answer. Adjust based on what you're watching:

  • Hard content → look up more. You understand deeply and pick up vocab faster, but you slow down.
  • Comfortable content → look up less. You move faster and build real-time comprehension closer to how you'll eventually just watch.

What should I watch?

Anything you enjoy. A good starting point is a show you've already watched in English. You know the plot, so you can focus on the Japanese without getting lost. These sites have anime rated by difficulty:


Passive immersion

Passive immersion means having Japanese audio on while your attention is elsewhere, be it on a walk, doing dishes, cooking. Less attention means fewer gains, but during genuinely low-focus tasks it's still useful background exposure. Don't let it replace active sessions.

practice

Sentence mining

Saving words from your immersion directly into Anki, so you study vocab that's actually useful to you.

Premade decks like Kaishi 1.5k are great for getting started. But once you're immersing, the most useful words depend on what you're watching. Mining bridges the two. Your Anki deck grows in the direction of your own content.

How it works: When you hover over a word with Yomitan, you can save it to Anki with one keypress. ASBPlayer also captures the sentence and an audio clip from the episode automatically, so each card has context built in.

Can't sentence mine yet due to device setup? Just continue with a premade deck for now. Mining is useful but not essential to start immersing.

Setup guide


Sentence Mining Guides

reading

Reading is one of the most powerful ways to grow your Japanese. Manga, novels, and visual novels each offer a different experience — pick whatever keeps you coming back.


Reading: manga

Manga is one of the best complements to anime! It builds reading speed, exposes you to more kanji in context, and the visual storytelling makes it easy to follow even at lower levels. The same 0–2 unknown rule applies: look up what you can, skip what's overwhelming, and keep moving.

To get Yomitan working on manga you need OCR, since the text is part of the image. Manatan is the easiest all-in-one option. It handles OCR automatically and works on desktop, iOS, and Android. Mokuro pre-processes manga into hoverable HTML pages for desktop use.


Reading: novels & light novels

Prose is harder than manga, no pictures to fill in the gaps, denser vocabulary, and more complex grammar. That said, web novels on Syosetu and Kakuyomu are written for casual reading and tend to be more accessible than retail books. For ebooks, the ッツ Reader renders Japanese text vertically in-browser and is compatible with Yomitan. If you're on mobile, Hoshi Reader (iOS) and Hoshi Reader Android both have first-class support for vertical text and dictionary lookups.

Note: Anna's Archive may be blocked in some regions — use a VPN if you can't access it.

Visual novels

Visual novels sit somewhere between reading and watching: voiced dialogue means you're training your ears at the same time as your reading, which makes them one of the most efficient immersion formats once you have some foundation. Text hooking with Textractor or JL lets you hover over any line with Yomitan, making lookups just as smooth as with anime subtitles. Ryuugames has a large catalogue of VNs available for download, and TheMoeWay has a full setup guide to get everything running.

NSFW warning: Ryuugames hosts adult visual novels alongside all-ages titles. Browse with that in mind.

Games

Games are harder to set up than VNs but extremely good for immersion, particularly RPGs, adventure games, and story-driven titles where you're reading a lot and the gameplay holds your attention. Text extraction varies by engine: Agent covers many emulator and PC game engines with script-based hooking, and GameSentenceMiner makes mining from games straightforward once you have it running.

practice

Improving listening

Subtitles carry a lot of the load. Once your reading is comfortable, it's time to train your ears directly.

After spending time with Japanese subtitles, your reading comprehension will grow faster than your listening. That's expected. The text does a lot of the work. Intensive listening is how you close that gap.


Intensive listening

Watch without subtitles visible. Only reveal them when you genuinely can't catch something. This forces you to actually hear the sounds, pitch, and rhythm rather than relying on text.

  1. 01 Open ASBPlayer with subtitles loaded but hidden. Watch normally.
  2. 02 When you hit a sentence you can't fully hear, replay it a few times and try to work it out.
  3. 03 Still can't get it? Reveal the subtitles. Look up 1–2 unknowns if needed. Skip if there are 3+.
  4. 04 Relisten to the sentence while reading the subtitle a few times to connect the sounds to the words.
  5. 05 Hide the subtitles again and continue.

Diversify your input

Anime is professionally recorded and clearly enunciated. Real speech isn't. Once you have a foundation, mix in other content: YouTube vlogs, variety shows, podcasts. People contract words, use slang, and speak over each other in ways anime doesn't prepare you for.

practice

Daily routine

Consistency matters more than volume. A steady hour every day beats a seven-hour session once a week.

Core routine

Anki 5–20 new cards + reviews · 20–30 min
Immersion 1–2 hours of anime with Japanese subs
Look-ups 0–2 unknowns per sentence · skip the rest
Passive Japanese audio during low-focus tasks · optional
You're aiming for 95% comprehension of the anime you watch. This is the point where you rarely need to look things up and scenes flow without effort.

Example day

Morning Anki: 20 new cards + reviews
Session 1 1 episode, reading focus · 25 min
Session 2 1 episode, intensive listening · 25 min
Session 3 Manga reading session · 40 min

How long does this stage take?

Building solid comprehension takes hundreds to thousands of hours. Progress will feel slow, then one day something clicks and it gets noticeably easier. That keeps happening. Just don't stop.

practice

Speaking

Output is a skill on top of input; you still need to practice it separately. The more you've immersed, the easier it gets.

Input first. You can't say what you haven't absorbed yet. Get comfortable with immersion before making output a priority, but there's no real harm in starting whenever.

What makes output sound natural

  • Grammar — not textbook-perfect, but correct where it matters. Which rules are flexible (e.g. すごい美味しい is technically wrong but totally normal) comes from immersion, not study.
  • Word choice — Japanese runs on set phrases. Using a word in the wrong context sounds wrong even with perfect grammar, like saying "to bode good weather" instead of "to bode well". You build this through exposure.
  • Social register — saying ありがとう to a compliment, overusing あなた, or skipping ます/です with strangers are all "English brain" mistakes. Natural output means knowing how Japanese people actually behave, not just what the words translate to.

Activities

  1. 01 Conversation practice — talk or text with a native speaker. iTalki, HelloTalk, Tandem, language exchange servers. Other learners are fine for low-pressure reps, but spend most of your time with natives.
  2. 02 Noticing — output reveals the gap between what you can understand and what you can actually produce. That gap puts your brain on alert, so phrases you're missing start sticking during immersion instead of sliding by. Stay aware of this as you work through the other activities.
  3. 03 Attentive listening — watch unscripted conversation (podcasts, variety streams, vlogs) and hunt for phrases you'd want to use. You're not watching for content, you're watching for form. ~15 min a day is enough. Stop when your focus drifts.
  4. 04 Self-corrected writing — write anything in Japanese, leave it an hour or two, then come back with fresh eyes. You don't need to know how to fix what feels off. Just mark it. Your brain registers the gap and picks up better phrasing during immersion. A Google Doc with highlights works well.
  5. 05 Active production — deliberately use a word you've only been passive on. Don't wait until you're confident. Say it and watch the reaction. A native speaker pausing, rephrasing, or repeating it back differently tells you more than any dictionary entry.

Writing kanji by hand

If you want to be able to write Japanese by hand, you need to practice it separately. Reading kanji and writing kanji are different skills. The Kanken Deck is the standard tool for this: it covers all jōyō kanji with stroke order, readings, and writing prompts, structured by Kanji Kentei level.

Don't start this early. Writing practice is only worth the time investment once you already recognise most jōyō kanji from reading. If you're still building reading comprehension, hold off.
exam prep

JLPT

The Japanese Language Proficiency Test runs N5 (beginner) to N1 (advanced). It's the most widely recognised certification for Japanese, useful for work, visas, and university admissions in Japan.

Immersion and JLPT prep work well together. The reading and listening sections reward exactly the kind of comprehension immersion builds. Grammar and vocab sections need more targeted study. That's where dedicated prep books come in.

Practice tests

Doing timed mock tests under real conditions is the most effective way to prepare. The JLPT format is specific. Knowing how questions are structured saves time on the day.


Reading material

The N2 and N1 reading sections pull heavily from formal written Japanese: essays, editorials, informational texts. Note.com (personal essays and commentary) and NHK Web (news articles) are good sources of level-appropriate native reading material you can mine with Yomitan.


Study books

The two dominant prep series approach the exam differently. Most serious learners combine them. Sou Matome for an accessible first pass, Kanzen Master to consolidate weak areas closer to the exam.

Shin Kanzen Master
新完全マスター · N4–N1 · thorough

Separate books per skill (grammar, vocab, kanji, reading, listening). Mostly in Japanese, demanding, and the go-to for people aiming to pass with a solid score rather than scrape by. Best from N3 upwards. Does not cover N5.

Nihongo Sou Matome
日本語総まとめ · N5–N1 · accessible

Each level covered in six weeks, one lesson per day, with English explanations. Goes all the way from N5 to N1. Better paced for beginners and good for building familiarity with the format before tackling Kanzen Master.


JLPT Anki decks (DoJG & Tango)

The Dictionary of Japanese Grammar (DoJG) is a Three-volume grammar reference covering Basic, Intermediate, and Advanced. The Anki deck has 629 grammar points, the front shows example sentences, back reveals the point, English equivalent, and usage.

The Tango Vocabulary Decks are graded vocab decks built around the most common words at each JLPT level. Cards include example sentences and audio. Run alongside your prep books to cover vocabulary systematically without having to mine it yourself.


Grammar resources

Grammar is the section most learners underestimate going into the JLPT. These tools cover every level from N5 to N1, with explanations in both English and Japanese.


Study platforms

Full-featured tools that combine grammar, kanji, and vocab in a structured SRS environment — useful if you want a single platform rather than assembling individual resources.

Anki

A spaced repetition flashcard app. This page covers what it is, how it works, how to set it up, and how to use it effectively.


What is Anki?

Anki is a free flashcard application built around spaced repetition. It schedules reviews at the optimal moment — right before your brain would forget something — so you spend almost no time on things you already know and focus entirely on things you don't. It's available on PC, Android (free), and iOS ($25 one-time purchase). AnkiWeb is a free browser alternative if you're on iOS.


How spaced repetition works

Every card has an interval — the number of days until Anki shows it to you again. When you answer a card:

  • Pass — the interval grows. You'll see it again further in the future.
  • Fail — the interval resets. The card comes back soon.

The result: cards you know well drift to weeks or months between reviews. Cards you keep failing come back daily. You never waste time drilling something you already have solid. Forgetting frequently early on is normal and expected — relearning is part of the process, and each relearn makes the memory stick longer.

Anki only works if you do it every day. You cannot pause your reviews — memory doesn't pause either. If you skip days, reviews pile up fast. If that happens, lower your new cards per day temporarily until you clear the backlog, then raise it again.

Installing the Kaishi 1.5k deck

Kaishi 1.5k is the recommended starter vocabulary deck. It covers the most common ~1,500 Japanese words with audio, example sentences, and kanji. Download the .apkg file from the link below, then open it — Anki will import it automatically.


Settings

After importing, hover over the Kaishi deck and click the cog icon → Options. Apply these settings:

  • Daily Limits → New cards/day: 20 (lower to 10 if reviews pile up)
  • Daily Limits → Maximum reviews/day: 9999 (uncapped — don't let Anki cut off due reviews)
  • New Cards → Learning steps: 1m 5m 10m
  • Lapses → Leech threshold: 20
  • Display Order → New/review order: Show before reviews
  • Timer → Show answer timer: ON
  • Advanced → FSRS: ON

Also set the global learn-ahead limit: Tools → Preferences → Scheduling → Learn ahead limit → 999.


Recommended add-ons

Go to Tools → Add-ons → Get Add-ons and paste each code below, one at a time. Restart Anki after installing all four.

  • 876946123 — Review Heatmap
  • 1046608507 — Advanced Browser
  • 1771074083 — Batch Editing
  • 613684242 — Pass/Fail (simplifies grading to two buttons)

After restarting, open deck options again while holding Shift and clicking the cog — this opens the add-on settings tab. Under General:

  • Automatically play alert: 10
  • Automatically show answer: 15
  • Automatically rate Again: 60

How to review cards

Click the deck and press Study Now. Each card shows a word on the front. For new cards, press Show Answer immediately without guessing — you haven't seen it yet.

On the back you'll see the reading, meaning, an example sentence, and audio. Listen to the audio and try to match what you hear to the text. You only need to remember two things:

  • The reading (how to pronounce it)
  • The meaning

Use this to decide Pass or Fail:

  • Remember both reading and meaning → Pass
  • Don't remember either → Fail
  • Remember reading only → Fail
  • Remember reading but not meaning at all → Fail
  • Remember reading, meaning is close enough → Pass

You don't need to match the dictionary definition word for word. Close enough counts.

When to start sentence mining

Once you finish Kaishi 1.5k (~1,500 words), you have enough of a foundation to start sentence mining — pulling words directly from content you're watching or reading into your own Anki deck. At that point your immersion will start generating more vocabulary than any premade deck can. See the page for how to set that up.

FAQ

Common questions from the community. Type anything below and the search will find the most relevant answer.


All questions

は is the Hiragana "ha," pronounced as "wa" only when used as a particle.

Example: おはよう = ohayou (ha), これは = kore wa (wa as particle). Greetings like こんにちは originally had は as a particle, so the "wa" reading stuck even as they became single words.
Learn Hiragana and Katakana first — the two basic syllabaries. Then move on to basic grammar, essential vocabulary (with kanji), and then immersion. See the for the full roadmap.
Both represent the same sounds but serve different purposes.

Hiragana: Normal Japanese words alongside kanji. Soft/warm feeling for onomatopoeia.
Katakana: Loanwords from non-Chinese languages (バイト, パン). Harsh/sharp feeling for onomatopoeia.

Example: あいうえお (Hiragana) vs アイウエオ (Katakana).
A small kana and the big one before it form a unit making their own combined sound.

Examples: きや = kiya, but きゃ = kya. りゅ = ryu, ちょ = cho.
It's like a silent beat in music — a pause before the next consonant. とぱ is two beats; とっぱ is three, with a silent one in the middle.
As much as you want to and no more than you can handle. Don't burn yourself out trying to hit someone else's "one hour a day" standard. Focus on quality over quantity.
Ideally know Hiragana/Katakana, N5 grammar, and ~1,000 common words (with kanji) before diving in. Without that foundation you won't be able to make much sense of content. See the for more.
Change your mindset. Say "I get to study" instead of "I have to study." Lower the bar so the bare minimum happens with almost no effort. Keep Japanese present in your daily life — people only change in response to their environments.
The order in which you encounter them through immersion — manga, anime, games, etc. There's no prescribed sequence that beats simply reading and watching real content.
Look it up. Search "[Word A] [Word B] difference" and you'll get a dedicated article with multiple examples instantly — faster and more thorough than asking anyone.
No. All reliable resources use Japanese writing. Skipping any part makes progress nearly impossible. Hiragana and Katakana can each be learned in a few hours. Kanji is best picked up through vocabulary over time.
No pronunciation difference in standard Japanese. Which character a word uses depends on etymology. When a compound is formed from a word starting with つ or ち, those usually become づ or ぢ. Otherwise, it must be memorised per word.
Start grammar, vocabulary, and kanji together.

Grammar: Cure Dolly, Japanese Ammo with Misa (YouTube), Genki, Tae Kim's Guide, or Bunpro.
Vocab & Kanji: Anki with the Kaishi 1.5k deck or WaniKani.

Duolingo is only useful for kana drilling.
Use a free dictionary. Jisho.org is the most popular, with example sentences and kanji readings. Takoboto is a great app alternative. Kanji you can't copy-paste can be drawn using Android's or Google Translate's handwriting input.
Disambiguation: かみ can mean paper (紙), hair (髪), or god (神) — kanji makes it clear.
Readability: No spaces in Japanese; kanji creates visual word boundaries.
Comprehension: Knowing a kanji's meaning often lets you guess unfamiliar words.
Culture: Kanji carry historical and literary depth impossible to replicate with kana alone.
Learn kanji through vocabulary — as part of real words, not in isolation. Studying kanji alone leads to confusion over readings and wasted time. Learn components to recognise shapes; pick up readings naturally as a side effect of learning words. Anki with the Kaishi 1.5k deck is the recommended starting point.
Not for serious learning. Duolingo was designed for European languages and handles Japanese poorly — rote kanji, missing grammar patterns, context-free vocab. It's fine for building a daily habit at the very start, but real progress needs better tools. See the for recommended resources.
Japanese uses pitch (high vs low) rather than stress to shape words. There are four patterns: 頭高 (first mora high), 中高 (accent in the middle), 尾高 (end high, heard before a particle), and 平板 (flat, no drop). Rules: the first two mora always have opposite pitch; once pitch drops it can't rise again. See the for training resources.
Demonstratives based on distance:

ko- = close to the speaker (this / here)
so- = close to the listener (that / there)
a- = far from both (that over there)
do- = question (which? / where?)

Applies to: kore/sore/are/dore (things), kono/sono/ano/dono (modifiers), koko/soko/asoko/doko (places), kocchi/socchi/acchi/docchi (directions).
Useful as a rough starting point, unreliable for specifics. AI has been wrong on grammar points, kanji readings, definitions, and synonym distinctions. You'd spend more time fact-checking than learning. Use dedicated tools: Jisho for vocab, Bunpro or Tae Kim for grammar, Anki for retention.
Through words. Learning kanji in isolation is time-consuming and inefficient — confusing readings, no context. Pick up kanji naturally as a side effect of building vocabulary.
Read more Japanese, regularly. Watch 7 Tricks That Instantly Boosted My Japanese Reading by Jared for practical tips. See the for reading material.
It's Kansai dialect (関西弁) for だよ — a casual sentence-ending particle meaning "it is" or "you know." Common in media set in Osaka or the Kansai region.
Use a spaced repetition system (SRS) like Anki. Anki calculates exactly when you need to review each card so nothing slips through the cracks. Start with a premade deck like Kaishi 1.5k — it covers the most common ~1,500 words with kanji and audio. Do 10–20 new cards per day alongside your reviews. Don't try to do too many at once; the review pile compounds quickly. Once you're immersing, transition to sentence mining your own cards from content you actually consume.
Spaced repetition is a study technique that shows you flashcards at increasing intervals based on how well you know them. If you get a card right, you see it again later. If you get it wrong, it comes back sooner. The result is that you spend the most time on things you don't know and almost no time on things you already know — which is dramatically more efficient than re-reading a list equally. Anki is the standard tool for this. It's free on PC and Android.
Stop adding new cards temporarily and clear your backlog first. The number one cause of a review pile-up is adding new cards too fast. Lower your daily new card limit (10–15 is sustainable for most people). Reviews compound: 20 new cards a day means roughly 80–100 reviews daily once cards mature. It's better to learn fewer words consistently than to add lots and abandon the deck entirely.
Sentence mining is taking words you encounter during immersion and turning them into Anki cards — using the original sentence as context. Instead of learning from a generic list, you learn words that are actually relevant to the content you're watching or reading.

The process: encounter an unknown word → look it up → save the sentence + definition as an Anki card → review it later.

It's more effective than premade decks for intermediate learners because the words come from content you care about, which makes them easier to remember. The standard tool for this alongside anime is ASBPlayer + Yomitan. Start premade decks first, transition to mining once you're actively immersing.
Both, at different stages. Start with a premade deck like Kaishi 1.5k — it gives you the ~1,000 most useful words fast without needing to understand content first. Once you're immersing regularly and have a foundation, gradually shift to sentence mining words from your own content. Mined cards are more memorable because they come from things you actually encountered and care about. Many learners run both in parallel: finish their premade deck reviews + add a few mined cards daily.
Active immersion means your full attention is on the Japanese content. You're reading, listening, looking things up — fully engaged. This is where the real gains happen.

Passive immersion means Japanese is playing in the background while your attention is partly elsewhere — washing dishes, walking, etc. The less attention you pay, the fewer gains you make. It's not useless, but it doesn't replace active sessions. Use passive immersion to squeeze more exposure out of dead time, not as a substitute for real study.
The difference comes down to how many look-ups you do.

Intensive: You pause frequently to look up unknown words and grammar. You understand more deeply and pick up vocab faster, but it's slower and more mentally tiring.
Extensive: You read/watch at natural pace, skipping over unknowns and relying on context. Builds real-time fluency and reading speed, but you need decent comprehension first for it to work.

Neither is strictly better — adjust based on difficulty. Use more look-ups on hard content, fewer on comfortable content.
Comprehensible input is the idea from linguist Stephen Krashen that you acquire language best when you understand most of what you're consuming — not 100%, but enough that the unfamiliar parts are graspable from context. Content where you understand nothing gives your brain nothing to latch onto. Content where you understand everything teaches you nothing new. The sweet spot is content you mostly follow with a handful of unknowns — sometimes called "i+1" (your current level plus one step beyond). That's why building a vocabulary and grammar foundation before immersing is important.
Progress is non-linear. The first few months feel slow and frustrating — you understand almost nothing. Then things start clicking. Most people doing 1–2 hours of immersion daily report noticeably improved comprehension around the 3–6 month mark, and genuine comfort with content around 1–2 years. Reaching near-native fluency typically takes thousands of hours of immersion total. The timeline shortens dramatically if you immerse more per day. The main thing is consistency — 30 minutes daily beats 5 hours once a week.
Start with content you've already seen in English — you know the plot, so you can focus on the Japanese without getting lost. Slice-of-life anime tends to use everyday vocabulary with clear pronunciation, making it more accessible than action or fantasy genres. Useful tools for finding level-appropriate content: Jiten.moe (anime by difficulty), JPDB.io (vocab difficulty rankings), LearnNatively (books and manga by level). The most important thing is to pick something you enjoy — motivation matters more than optimal difficulty.
The immersion method is a language acquisition approach where the bulk of your learning comes from consuming native content in the target language rather than studying from textbooks. AJATT (All Japanese All The Time) was an influential blog by Khatzumoto that popularised the idea of surrounding yourself with Japanese constantly — media, music, background audio, phone settings, everything — to replicate the environment of living in Japan from anywhere. The modern approach is less extreme but keeps the core idea: spend as much time as possible with the language through things you actually enjoy.
Textbooks teach you rules but can't show you how those rules play out across the thousands of natural contexts you'll encounter in real Japanese. Language is too vast for any classroom to cover — native speakers use phrases, nuances, and register shifts that textbooks simply don't document. Immersion gives you real exposure to how the language actually works, building the intuition (automaticity) that lets you understand without translating in your head. Textbooks and grammar guides are still useful as a foundation — but they're the rope you build to help climb the mountain, not the climbing itself.
Yomitan is a browser extension that gives you an instant pop-up dictionary when you hover over (or select) any Japanese text in your browser. It can show vocab definitions, kanji readings, pitch accent, grammar explanations, and more depending on which dictionaries you install. It's essential for immersion — instead of copying and pasting words into Jisho constantly, you hover and get an answer instantly. You can also send cards directly to Anki from it for sentence mining. Setup guide: learnjapanese.moe/yomichan.
There's no universal rule, but output is most productive once you have a solid input foundation. Speaking before you've absorbed enough of the language means you'll reinforce incorrect patterns. That said, don't delay indefinitely — many learners get so used to consuming that they never push themselves to produce. A practical approach: start with low-stakes textual output (texting, Discord, writing in Japanese) before speaking, since writing gives you time to think. Aim to have a reasonable comprehension of the language before attempting sustained conversation. The covers this in detail.
Listening comprehension lags behind reading for most learners because reading lets you control the pace. The fix is deliberate listening practice — not just having audio on in the background. One effective method is intensive listening: watch without subtitles, stop on sentences you can't parse, replay them a few times, then reveal the subtitle to confirm. This forces your brain to actually process sounds rather than reading to understand. See the for the full process. Consistency matters more than technique — just listen more.
PC (Windows): Go to Settings → Time & Language → Language & Region → Add Japanese. Once added, you'll have a Microsoft IME. Switch between English and Japanese with Alt+` or the taskbar icon. Type romaji and it converts to kana automatically — press Space to convert to kanji.

Mac: System Preferences → Keyboard → Input Sources → add Hiragana.

Android: Settings → General Management → Language → Add Japanese keyboard (Gboard works well).

iOS: Settings → General → Keyboard → Keyboards → Add New Keyboard → Japanese (Romaji).
The JLPT (Japanese Language Proficiency Test) has five levels, N5 through N1, with N5 being beginner and N1 being the most advanced. Rough benchmarks:

N5: Basic greetings, simple sentences, ~800 words.
N4: Everyday situations, basic conversations, ~1,500 words.
N3: Everyday topics at moderate difficulty, ~3,750 words.
N2: Near-fluent reading of newspapers and complex text, ~6,000 words.
N1: Broad reading and listening comprehension of native-level content, ~10,000+ words.

N2 is considered the minimum for working in a Japanese-language environment. N1 is widely respected as a credential. See the for prep resources.
Yes — reading is one of the most efficient forms of immersion because you control the pace. Manga is great for beginners since images provide context. Visual novels are excellent because you get audio alongside the text. Light novels are pure reading and require stronger vocabulary. A few starting points:

Manga: klmanga.pics, Shonen Jump Plus, Pixiv Comics.
Visual Novels: learnjapanese.moe/vn has a full setup guide.
Web novels: Kakuyomu and Narou for free content.
