Japanese Kanji Study is an Android kanji learning application developed by Chase Colburn. It covers over 6,000 kanji alongside hiragana and katakana, organizing characters by JLPT level (N5–N1), Jōyō grade, school grade, and frequency, with SRS-based flashcards, multiple-choice quizzes, and stroke-order writing practice.
In-Depth Explanation
Platform: Android (Google Play: `com.mindtwisted.kanjistudy`). 1,000,000+ downloads; 4.9 stars with over 57,000 ratings. Partial free tier; full content requires a one-time purchase. Optional paid add-ons: Guided Study (SRS-driven lesson progression), Graded Reading Sets, and Outlier Kanji Dictionary integration.
Japanese Kanji Study organizes its character database by multiple classification schemes — JLPT level (N5–N1), school grade (1–6), Jōyō status, and a frequency-ranked list — so learners can focus on the subset most relevant to their goals. Each character entry includes the English keyword meaning, on-yomi and kun-yomi readings, stroke order animation, example vocabulary, and radical decomposition.
Study Modes
The app offers four main study interactions: flashcard review (multiple card types: English-to-kanji, kanji-to-English, reading recognition, and meaning recognition); multiple-choice quizzes; writing practice with stroke-order tracing and correction feedback; and a search dictionary for ad-hoc lookup by stroke count, radical, SKIP pattern, or English keyword.
SRS and Guided Study
The Guided Study add-on applies spaced repetition scheduling across all study modes, surfacing characters at algorithmically determined intervals based on performance history. Without the add-on, flashcards operate in manual review mode rather than SRS-scheduled practice.
Outlier Kanji Dictionary Integration
An optional in-app purchase integrates the Outlier Kanji Dictionary, a scholarly resource from Outlier Linguistics that details the historical component composition of characters. Outlier content provides etymologically grounded breakdowns beyond the simplified radical mnemonics common in mainstream learner resources.
History
Japanese Kanji Study has been available on Android for several years and consistently ranks among the highest-rated Japanese-learning applications on Google Play, reaching over one million downloads. Developer Chase Colburn has maintained active updates, most recently in May 2026. The Outlier Kanji Dictionary partnership connects the app to Outlier Linguistics’ independent scholarly dictionary project.
Common Misconceptions
“The SRS feature is included in the free tier.”
The Guided Study module, which enables spaced repetition scheduling, is a separate paid add-on. The base flashcard functions are available without it, but review order is manual rather than algorithmically scheduled.
“The app only covers kanji recognition — not vocabulary.”
Each character entry includes example vocabulary and sentences, making the app useful for building reading vocabulary alongside kanji recognition. It does not function as a standalone grammar course.
Social Media Sentiment
On r/LearnJapanese, Japanese Kanji Study receives consistent positive mentions and is frequently cited as a strong alternative to WaniKani for learners who prefer a one-time purchase over a subscription model. Its 4.9 Play Store rating is often noted as unusually high for a study app. Some users distinguish between using the app for character recognition versus active writing practice, noting the writing module requires deliberate engagement. The Outlier Kanji Dictionary integration draws positive commentary from learners familiar with Outlier Linguistics’ analytical approach to character etymology.
