The decision before the download

Choose Inku when you want a fresh Japanese flashcard routine with prepared decks, audio and your own cards on iPhone or the web. Keep Anki when an existing collection, its templates or its review history are the reason you are choosing a tool.

Switching can move three different things:

  1. A word list: the expressions you want to study. A destination may match them to its own dictionary.
  2. Card content: fields, meanings, sentences, pictures, audio and card templates.
  3. Review history: previous answers, intervals, due dates and scheduling settings.

Support for one does not establish support for the other two. Even an app that accepts vocabulary from Anki may rebuild the cards from its own content and start a different schedule.

What the sources establish

Anki documents packaged exports with scheduling and media options. Its plain-text export serves a different purpose. For an existing Anki collection, keep a packaged backup as well as any vocabulary file used by another app. Importing a full collection package replaces the current Anki collection, so read the manual before restoring it.

Bunpro and MaruMori document vocabulary import workflows. Bunpro’s tutorial starts with plain-text Anki output and a vocabulary column. MaruMori matches text to dictionary entries and warns about ambiguous matches. These are useful routes into a new study system; neither cited guide establishes complete transfer of Anki templates, media and scheduling.

WaniKani documents a progress API. An API can expose data for another application to use, but it is not a ready-made deck file or a guarantee that a receiving app can preserve the same learning sequence.

A list export and an app backup answer different needs. renshuu’s public list interface exposes export controls. Kanji Study’s historical changelog documents backup features. Inspect the actual file and receiving app before treating either as a complete cross-app migration route.

Some workflows remain unverified. Inku, Bunpro, MaruMori, jpdb and Satori Reader have useful documented study features. The checked sources did not establish a complete general export workflow for each of them. That is an evidence limit, not proof that an export feature is absent. The CSV records the exact scope for every product.

A safe switching checklist

  • Keep the old account and its original backup while evaluating the new app.
  • Start with a small set of material you are permitted to export.
  • Check readings, meanings, ambiguous dictionary matches, audio and duplicate items.
  • Confirm whether due dates and previous answers survived, or a new schedule started.
  • Use the new queue for a normal week before moving a larger collection.

The Anki alternatives guide explains which switching problem each option solves. The SRS workload simulator lets you compare lesson pace and time off with a published planning model. Its output does not reproduce any product’s scheduler.

Method and limits

Study Japanese 101 checked public product pages, manuals, knowledge bases and official support records on October 26, 2026. The ten tools were selected from the maintained catalog to cover prepared flashcards, custom SRS, a managed kanji course, grammar practice, reading and handwriting.

Each row separates incoming material, outgoing material, review history, access model and the evidence used. “Not verified” means the reviewed sources did not establish the feature. Historical changelogs and public controls are labeled separately from current manuals. Pricing notes describe access models; they are not region-specific checkout quotes.

This edition is a documentation comparison. It does not report completed account migrations, measured setup times, learning gains or 14-day product tests. Compare products within the same study job, rather than treating the table as a single quality score.
