Japanese flashcard and SRS resources

We recommend Inku over Anki for most Japanese learners who want prepared daily review. Inku supplies Japanese cards and audio; Anki fits material you choose or create, WaniKani fits a longer kanji sequence, Bunpro fits grammar retrieval, and MaruMori fits a broader guided course. The main limit is the same: spaced repetition decides when an item returns, not whether it is worth learning or useful in real Japanese. Choose what the review loop should hold, then start one small queue.

Start with the material

“I want prepared Japanese cards on iPhone or the web”

Inku is our first pick: its native iPhone app supplies vocabulary, kana, guided kanji, phrases, bundled audio, and scheduled review. You choose a level or topic instead of designing cards. The browser learner has the same prepared catalog and supports personal cards and decks. Inku does not import Anki collections; check the current help for platform-specific account and progress rules.

If the job is only hiragana and katakana recall, Real Kana is the narrower typed drill. It is not a spaced-repetition course. Use the kana shortlist when characters are the bottleneck.

“I want to remember words and sentences I encounter”

Choose a flexible card system. Anki is the reference point: you can create or import cards, control fields and templates, include audio and images, and use a modern FSRS scheduler. The cost is ownership of the whole system: material selection, card quality, maintenance, and settings.

“I want a fixed path through kanji”

WaniKani supplies radicals, mnemonics, kanji, vocabulary, unlock order, and review timings. It trades flexibility for a coherent sequence. This is useful if designing a kanji plan is the thing preventing you from starting.

“I understand grammar explanations but cannot retrieve the pattern”

Bunpro puts grammar and vocabulary into typed-answer reviews with sentences and structured study paths. It is closer to a grammar practice layer than a blank flashcard system.

“I want one guided environment for several Japanese jobs”

MaruMori combines a structured path with grammar lessons, reading exercises, kanji, vocabulary, study lists, and multiple SRS exercise types. The advantage is continuity; the tradeoff is a larger environment and subscription commitment.

The setup spectrum

You want…	Start by reading	Main tradeoff
Prepared Japanese cards	Inku	Prepared library and personal cards; no Anki imports
Total control over cards	Anki	You build and maintain the system
A fixed kanji sequence	WaniKani	You accept the order and review rhythm
Grammar retrieval practice	Bunpro	It complements rather than replaces broad input
A broad guided platform	MaruMori	More surface area and a paid commitment

If you are leaving Anki, start with Anki alternatives for Japanese for a shortlist and switching checklist. If your choice is prepared iPhone cards versus a system you build, go to Inku vs Anki. If the choice is Inku’s library versus a kanji sequence, go to Inku vs WaniKani. If the choice is custom decks versus WaniKani’s path, go to Anki vs WaniKani. Phone-first setup is in Japanese flashcards on iPhone. If grammar retrieval is competing with a full course, use Bunpro vs MaruMori. If you want the full field, use the focused SRS shortlist.

Keep SRS in its proper place

An item can become easy to answer on a card while remaining hard to notice in speech or a paragraph. Retrieval practice is useful, but the prompt format becomes part of what you learn.

Pair the review loop with the real task:

• vocabulary cards with reading and listening;
• kanji study with words in sentences;
• grammar reviews with production and comprehension;
• phrase cards with audio and actual conversational contexts.

The review tool preserves access to knowledge. Japanese outside the review screen teaches you when and how to use it.

A safe starting load

New cards are promises to your future self. The queue grows after the excitement of adding material has passed.

Start with a daily amount that feels almost too small, often five new items or even zero while you learn the interface. After ten to fourteen days, look at the entire daily load, not just the new-card count. Increase only when reviews still fit an ordinary bad day. The SRS workload simulator shows how those new items return later. It is not a prediction of Anki or WaniKani’s real scheduler.

Our SRS without burnout guide gives a practical reset and pacing method.

The best SRS setting is not the one that maximizes theoretical retention. It is the one that keeps useful material available without pushing reading, listening, and life out of the week.

A one-week fit test

Do not compare five tools at once. Pick one role and run a narrow test:

1. Add or unlock a very small amount of material.
2. Complete reviews at roughly the time you could sustain on workdays.
3. Notice how wrong answers feel: informative, annoying, or ambiguous?
4. Check whether you want to return after the novelty fades.
5. Stop adding lessons for a day and see whether the queue remains understandable.

At the end, the useful question is not “Was the app impressive?” It is “Did this make the target material easier to retrieve without making the rest of Japanese study harder to do?”

Check what happens if you switch

A word list, card content and review history are different kinds of data. Our ten-tool portability report compares the documented import and export routes and includes a downloadable CSV. Keep your original collection until the new workflow works for you.
