Anki Japanese Settings: The Optimal Setup Guide

Most people who download Anki for the first time do the same thing: they install a deck, open their first review session, and leave every setting exactly as it shipped. Three weeks later, they have 450 cards waiting on a Wednesday morning, panic, and delete the app.

The default Anki settings are not designed for Japanese learners. They’re not designed for long-term language acquisition at all. They’re built for generic studying, short-term retention of a fixed set of facts, which creates specific, predictable problems when you’re trying to retain thousands of vocabulary cards across years of study.

This guide covers the Anki Japanese settings that actually determine whether your habit survives: the algorithm choice, the review limits, the learning steps, the display fixes for Japanese text, and the small decisions that separate a sustainable daily practice from a review pile that erodes your motivation every time you open the app.

1. The Most Important Decision: FSRS or SM-2?

Before touching anything else, you need to decide which spaced repetition algorithm you’re running. This single setting affects everything downstream: your review volume, your retention accuracy, and whether you’ll eventually hit the problem called ease hell.

SM-2: How Anki Used to Work

Anki shipped for years with SM-2, an algorithm developed in the 1980s by Piotr Wozniak. SM-2 schedules reviews by adjusting an “ease factor” on each card based on your ratings. Mark a card as Hard too many times and its ease factor drops, scheduling it more frequently. Keep marking it Hard and it eventually lands in daily-review territory regardless of whether you actually know it.

This is a structural flaw, not a user error. SM-2 has no real recovery mechanism for low-ease cards. The problem compounds quietly over months until a significant percentage of your reviews are cards you genuinely know, cycling back at two-day intervals because their ease factors are broken.

FSRS: The Modern Replacement

FSRS (Free Spaced Repetition Scheduler) was developed by researcher Jarrett Ye and integrated natively into Anki in late 2023. It works differently at a fundamental level. Instead of adjusting ease factors based on individual ratings, FSRS builds a predictive model of your memory for each specific card using your full review history. It then schedules that card to hit a target retention rate, say, 85%, rather than reacting mechanically to how you rated your last recall.

The practical difference for Japanese learners:

Fewer unnecessary reviews on cards you actually know
No ease hell: the ease factor concept doesn’t exist in FSRS
Smarter scheduling that adapts as your memory of a specific card stabilizes

The recommendation for 2026: use FSRS. It’s better in every measurable way and it’s now built into Anki’s core, so there’s no additional setup complexity.

To enable it, open any deck’s options (the gear icon next to the deck name), scroll to the FSRS section, and toggle it on. Set your desired retention to 0.85 as a starting point. Once you have at least 1,000 reviews in your history, click the Optimize button in the same settings panel to calibrate the algorithm to your actual memory data.

2. The Settings That Control Your Review Volume

These two numbers determine whether your Anki habit stays manageable. Most review pile problems trace back to getting one or both of them wrong.

New Cards Per Day

This is the highest-leverage setting in your deck options. Every new card you introduce today becomes a recurring review across the next several months. The relationship is not linear, it front-loads learning but back-loads reviews, and the back-loading is where most learners collapse.

Set new cards to 20 per day, maintain it for two months, and you’ll have a daily review load of roughly 150 to 200 cards on top of new cards. Add a few bad days where you miss reviews, and the pile grows faster than you can burn it down.

Recommended starting points:

Study situation	New cards per day
Complete beginner, building the habit	5 to 10
Committed learner, stable daily practice	10 to 15
Serious study with immersion alongside Anki	15 to 20 (maximum)

There is no situation where a beginner should add more than 20 new cards per day. The upper limit is not about cognitive load during the session, it’s about the review debt that accumulates over weeks and months.

The most common version of this mistake: starting at 20 or 30 new cards because you’re motivated, building a 300-card backlog over two months, and then feeling so overwhelmed that you reset or abandon the deck entirely. Start at 10. You can always add more once you’ve proven to yourself that the daily habit is stable.

Hey, How Many Anki Cards Per Day for Japanese is a good idea?

Maximum Reviews Per Day

Set this to 9999. Do not cap your daily reviews.

Reviews are cards you’ve already learned. They’re not optional. When Anki defers an overdue card because you’ve hit a review cap, it pushes that card to the next day’s queue, which makes tomorrow’s load larger. Review debt compounds. The cap feels like it’s helping in the moment and actively makes things worse over time.

The only control you should use to manage workload is new cards per day, not the review limit. If your reviews are already out of control, the fix is to stop adding new cards and work through the backlog, not to hide the problem behind a cap.

3. Learning Steps: What They Are and What to Set Them To

Learning steps are the intervals Anki uses to drill a new card within the same session before it graduates to proper spaced repetition. Each time you rate a card as Good during the learning phase, it moves to the next step. Complete all the steps successfully and the card graduates, getting its first real review interval.

Anki’s default learning steps are 1m 10m. That means a new card appears once immediately, and once 10 minutes later if you got it right. Pass both, and it graduates.

For Japanese vocabulary, this is too shallow. Two correct recalls ten minutes apart don’t create a durable memory trace. Cards that graduate too quickly tend to fail again within two or three days, landing back in a shortened re-learning sequence and adding unnecessary friction.

Recommended Learning Steps for Japanese

A three-step sequence works better:

1m 10m 1d

This adds a third step at one day. A card you learn today comes back tomorrow before it graduates to its first real interval. You’ll see higher pass rates at graduation and fewer early lapses pulling cards out of the main review queue.

Some learners find this sequence even better:

1m 5m 10m 1d

The extra 5-minute step helps if you’re regularly blanking on cards within the same session. It’s slightly more time-consuming per card during the learning phase, but can reduce the volume of same-day re-learns. Try the three-step version first.

Graduating Interval

Set to 1 day. This is the interval a card receives when it completes all learning steps normally. A graduating interval of 1 means you’ll see it again tomorrow. That’s correct.

Easy Interval

Set to 4 days. This applies only when you press “Easy” during the learning phase, which you probably shouldn’t do often. The Easy button during learning signals that the card was too simple to drill at all, not that you learned it faster. Pressing Easy on cards that are merely familiar is a shortcut that tends to schedule them too far out before they’re actually stable.

A practical recommendation: during your first six months with Anki, treat Easy as a button you almost never press. Use Again, Hard, and Good. Easy is there for things like single-character hiragana (ひらがな) and katakana (カタカナ) cards that genuinely don’t need drilling.

4. Lapses and What Happens When You Forget a Card

When you press Again on a card that has already graduated, it lapses. Anki has a set of options that control what happens next.

Re-learning Steps

Similar to learning steps, but for cards you’ve forgotten. A common setting is:

10m

A single 10-minute step is reasonable for most lapsed cards. You don’t need to re-drill a lapsed card as heavily as a new card. If you’re using FSRS, the algorithm handles the re-scheduled interval intelligently. If you’re on SM-2, set the New Interval to 0.7, which means a lapsed card restarts at 70% of the interval it was at before it failed.

Leech Threshold

A leech is a card you’ve failed repeatedly. Anki’s default threshold is 8 failures. At that point, it tags the card as a leech and optionally suspends it from your deck.

For Japanese learners, 8 is too high. By the time a card has failed 8 times, you’ve spent an outsized amount of review time on something that clearly isn’t sticking through normal repetition. That card needs a different approach: a mnemonic, additional context, a better example sentence, or a brief break before returning to it.

Set the leech threshold to 4 or 5. When a card becomes a leech, let it suspend. Go into your Leech tag, look at the suspended cards periodically, and deal with them deliberately rather than continuing to grind cards that aren’t working through brute repetition.

5. Display Settings for Japanese

The Chinese Character Problem

If you’ve imported a Japanese deck and some of your kanji look slightly wrong, you’re likely seeing a font issue. Anki’s default CJK font renders Chinese glyph variants for characters that have distinct Japanese forms.

Japanese and Chinese share many kanji, but the written forms are sometimes different. Characters like 直, 令, and 骨 (ほね) have glyphs that vary between Japanese and Chinese typographic conventions. If Anki is defaulting to a Chinese font, you’re studying incorrect visual forms of some kanji.

The fix lives in your card template. Access it through the card browser (Browse in the top menu), then click Cards in the editor. In the Front Template, wrap your main field in a div with a specified Japanese font:

<div lang="ja" style="font-family: 'Noto Sans JP', 'Yu Gothic', 'Meiryo', sans-serif;">
{{Front}}
</div>

Noto Sans JP is the cleanest cross-platform option. Yu Gothic works on Windows. Meiryo is an older Windows standby that still renders correctly on most systems.

Apply the same font wrapper to your Back Template and any Styling section that specifies a global font.

Furigana Display

Pre-made Japanese decks like Kaishi 1.5k store furigana in bracket notation inside the field: 漢字[かんじ]. Anki won’t automatically render this as furigana sitting above the kanji. It’ll just show the bracket text.

There are two ways to make furigana display correctly:

Option 1, Japanese Support add-on: Install the Japanese Support add-on from AnkiWeb. It adds a ruby text handler that parses the bracket notation and renders furigana visually. This is the recommended approach for most learners.

Option 2, Card template helper: Use the furigana: field prefix in your card template ({{furigana:Expression}}). This works without the add-on but requires your field to be named specifically and the card template to reference it correctly.

The Japanese Support add-on handles both furigana display and furigana generation, which means it can also automatically add readings to cards you create yourself. It’s one of the first add-ons you should install.

6. Card Types for Japanese: A Quick Overview

The type of card you use affects how you configure learning steps, audio settings, and what the Japanese Support add-on does. There are three main formats in the Japanese learning community.

Vocabulary cards have a Japanese word on the front and the reading plus meaning on the back. Simple, widely used, and what most starter decks like Kaishi 1.5k use by default. Good for beginners building core vocabulary recognition.

Sentence cards have a complete Japanese sentence on the front, with the target word highlighted or bolded. The back shows the meaning and reading. Better for building reading fluency alongside vocabulary, since you’re processing the word in grammatical context rather than in isolation. Most intermediate learners migrate toward sentence cards once they have a vocabulary base of around 1,000 to 1,500 words.

Anime cards are a specific format developed in the immersion-learning community. The front shows a screenshot from a video, the audio clip, and the target word in context. The back shows the full sentence, reading, and definition. Extremely effective for intermediate learners doing regular immersion, but requires more technical setup through tools like Yomitan and mpv with the mpv-sub2srs script.

Your settings don’t need to change dramatically between these formats, but your learning steps and card template will vary. Sentence cards benefit from slightly longer learning steps since they’re harder to recall on first exposure. Anime cards require audio settings to be configured in the card template.

7. Which Deck Should You Start With?

The settings only work if the deck is worth using. For beginners, the question is usually Kaishi 1.5k versus Core 2k.

Kaishi 1.5k is the community recommendation in 2026. It was built to fix the problems with Core 2k: outdated vocabulary choices, inconsistent sentence quality, and some audio issues. Kaishi uses high-frequency vocabulary selected from a modern frequency analysis, clean example sentences, and better audio recordings. The 1.5k card count is intentional, it covers the most important vocabulary without overwhelming new learners before they’re ready to start mining their own cards.

Core 2k is older but still functional. If you’re already partway through it and the habit is working, there’s no compelling reason to restart. If you’re choosing fresh, pick Kaishi.

Both decks use vocabulary cards by default. Once you reach roughly the N4 level, around 1,500 to 2,000 words, many learners transition to personal mining decks that pull vocabulary directly from native content they’re consuming. At that point, the starter deck has done its job.

8. Two Settings Mistakes That Break Most Learners

Ease Hell (SM-2 Users)

If you’ve been using Anki with SM-2 for several months and you’re reviewing the same cards every day or two, ease hell is probably the culprit. It develops when cards accumulate Hard ratings. Each Hard rating nudges a card’s ease factor down slightly. Enough Hard ratings and the card’s ease factor drops below 130%, which is roughly the threshold where Anki starts scheduling the card so frequently that it effectively never graduates to longer intervals.

The structural fix is switching to FSRS, which doesn’t use ease factors. The card-by-card fix on SM-2 is an add-on that resets ease factors across your deck, usually called “Reset Ease” or included in the ResetEZ add-on. Both work. FSRS is the better long-term answer.

Ignoring the Leech Problem

Leeches are often treated as a nuisance rather than a signal. When a card fails repeatedly, it’s telling you something specific: this card’s current representation isn’t working. The image, the sentence, or the context you’ve associated with it isn’t sticking. Grinding through it with repeated reviews isn’t a solution.

Set your leech threshold to 4 or 5 and treat suspended leeches as a periodic maintenance task. Go into your Leech tag once a week, look at the suspended cards, and do one of the following with each:

Add a note or mnemonic to the back of the card
Find a better example sentence that gives the word clearer context
Create an image card if the word is highly visual
Delete the card if the vocabulary isn’t relevant to your current level

Don’t just un-suspend them and hope the next round of reviews goes differently. They’ll fail again.

9. Essential Add-Ons for Japanese

Anki’s base functionality covers the basics, but three add-ons make a measurable difference for Japanese learners specifically.

Japanese Support is the first thing to install. It adds furigana generation directly inside Anki, type a kanji word into a field, press the shortcut, and the add-on generates the reading automatically in bracket notation. It also handles furigana display through the card template integration described in the display settings section. Available free on AnkiWeb.

AnkiConnect runs as a background service that lets external tools communicate with Anki over a local connection. It’s required for Yomitan integration, the browser extension that lets you hover over any word in any browser tab, get a definition, and send the card directly to Anki with one click. Without AnkiConnect, you can’t use the automatic mining workflow that most serious immersion learners rely on.

FSRS Helper provides additional controls for the FSRS algorithm: a more detailed retention statistics display, a custom scheduler with extra parameters, and some useful deck-level analysis tools. Not essential on day one, but worth installing once you’ve been using FSRS for a couple of months and want better visibility into how the algorithm is performing on your specific cards.

What are the best Anki settings for Japanese beginners?

Start with FSRS enabled and a target retention of 0.85, 10 new cards per day, maximum reviews set to 9999, and learning steps of 1m 10m 1d. Install the Japanese Support add-on and use the Kaishi 1.5k deck. These settings will keep daily review load manageable while building a solid vocabulary base from the first week.

Should I use FSRS or SM-2 for Japanese?

FSRS. It’s more accurate, produces fewer unnecessary reviews, and structurally prevents the ease hell problem that eventually breaks long-term SM-2 users. Enable it in your deck options, set your desired retention to 0.85, and run the optimizer once you have enough review history to calibrate it.

How many new cards per day is realistic for Japanese?

Ten to fifteen cards per day is the sustainable range for most serious learners. Below ten, progress feels slow but the habit is stable. Above twenty, review debt starts accumulating faster than most learners can handle alongside reading, grammar study, and listening practice. Start at ten and only increase if your daily reviews stay consistently under control for at least four weeks.

Why is Anki showing Chinese character variants for my Japanese kanji?

It’s a font issue. Anki’s default CJK font uses Chinese glyph variants for shared characters. Fix it by specifying a Japanese-specific font like Noto Sans JP or Meiryo in your card template and adding lang="ja" to the HTML wrapper of your card fields. See our full article at Fix: Anki Japanese Font Showing Chinese Characters

What is ease hell and how do I avoid it?

Ease hell is a long-term SM-2 problem. Cards that get rated Hard repeatedly end up with very low ease factors and get scheduled almost daily, clogging your reviews with cards you actually know. The cleanest solution is switching to FSRS, which doesn’t use ease factors. If you’re staying on SM-2, be disciplined about not pressing Hard on cards that you recalled correctly but slowly, reserve Hard for genuine near-misses.

What retention rate should I target in Anki for Japanese?

0.85 (85%) is the starting point most experienced Japanese learners recommend. Anki’s default is 0.90, which is higher accuracy but produces noticeably more reviews. For the volume of vocabulary Japanese requires over several years of study, 0.85 offers a better balance between retention accuracy and sustainable review load. You can adjust it after running the FSRS optimizer and seeing what your actual review volume looks like.

Is the Anki iPhone app worth the $25 cost?

It depends on whether you review on iPhone. Anki for iOS is the only way to sync your reviews between desktop and iPhone. The one-time payment funds ongoing development of the free desktop and Android versions. If mobile reviewing is part of your daily practice, the cost is justified. If you study exclusively on a laptop, you don’t need it.

Should I reset my Anki deck if I’ve fallen behind on reviews?

Generally, no. Resetting loses your review history and the scheduling data FSRS uses to model your memory accurately. A better approach is to stop adding new cards entirely, reduce maximum reviews temporarily if you’re returning after a long gap, and work through the backlog over one to two weeks before resuming normal settings. A reset is sometimes the right call, but it should be a deliberate decision, not a reaction to a bad month.
Should I Reset My Anki Deck and Start Over?

The two settings that matter most are FSRS and new cards per day. Everything else in this guide, the learning steps, the font fix, the add-ons, makes a real difference, but none of it saves a deck where you added 25 new cards per day for six weeks and now have 500 reviews staring at you.

Start conservative. Let your daily review count prove itself for a month before increasing new cards. The learners who stick with Anki for two or three years and actually reach a useful vocabulary size almost always describe the same trajectory: they started slow, got bored being conservative, added cards carefully, and eventually had a system that ran without drama. The learners who quit almost always describe starting aggressive and burning out.
