The PeraNabi Approach

Tracks Japanese by Concept

Practice is linked to specific grammar, vocabulary, and kanji concepts, so your results can show which ones need more work.

Review Adjusts as You Learn

Your results and the time since your last review help decide what comes back next.

Starts at Your Level

A short Starting Check gives PeraNabi a first picture of what you know, so your practice begins where you are.

Progress Tracking

Progress bars on the Study page show how much of the material you have covered. The Mind Map shows 588 concepts in 3D or 2D, with color estimating how solid each one is from the practice you record in PeraNabi.

Ways to Practice

PeraNabi offers a variety of Japanese practice activities.

Sentence Questions

Multiple-choice questions on real sentences: pick the particle, form, or word that makes the sentence work.

Vocabulary & Kanji Cards

Reading, meaning, and an example for a word or kanji, with a quick self-rating that feeds your schedule.

Listening

Short dialogues and audio-first cards: listen, understand, then check.

Sentence Building

Arrange Japanese pieces into the right order to build the sentence. Appears once the words in a sentence are already familiar to you.

Reading Stories

Short N5-level stories with comprehension checks. Stories unlock as your vocabulary grows, so early on you may not see one yet.

Kanji Writing

Draw supported kanji by hand; recognition runs locally in your browser.

Speaking Practice

Say Japanese words and phrases aloud, then check what your browser understood.

Verb Conjugations

Conjugation practice for the verbs you are learning comes up during your sessions: polite, te-form, negative, and past.
