Kanjijo · free to start on iPhone

A JLPT app that takes you from N5 to N1

Kanjijo follows the JLPT level by level: the kanji, words and grammar each level expects, the reading and listening sections as the test sets them, and 35 full mock tests to finish. Free to start on iPhone.

Everything the test checks, sorted by level

The JLPT has three sections: vocabulary and kanji, grammar and reading, and listening. Kanjijo builds each one into the path rather than leaving them for the last month. Every level has its own kanji, words and grammar, taught in 324 lessons that unlock in order, and every lesson ends with a test that makes you recall the answer instead of recognising it.

Reading and listening the way the exam sets them

Recognising words in a list is not the same as reading a passage against the clock. The JLPT reading track has 95 graded lessons from N5 to N1 written in the formats the exam uses, and the listening track has 95 lessons with native audio. Eighty dictation lessons cut from real native videos train you to catch every word at natural speed.

35 full mock tests, seven for each level

When a level is almost done, sit a full mock test with the timing of the real exam. Each level has seven, so you can test, review the mistakes by section and test again before the real day. If you are not sure where to start, the free JLPT level test places you in five minutes.

Reviews timed for you, not for a calendar

Every kanji, word and grammar point you learn goes into a seven-stage spaced-repetition system that grows from Seed to Ancient Tree. Items you find hard come back sooner, items you know wait longer, so the daily review stays short even with thousands of items in it.

A study day with Kanjijo

  1. Take the free level test to find your starting level.
  2. Learn one new lesson in each track a day: kanji, vocabulary, grammar, reading, listening.
  3. Clear the reviews the SRS schedules for you, usually 10 to 20 minutes.
  4. At the end of a level, sit a full mock test and review your weakest section.

Good to know

  • Kanjijo is on iPhone today; an Android version is on the way.
  • It prepares you for the test; registration and test dates are handled by the official JLPT organisers in your country.

Frequently asked questions

Is there an app that covers the JLPT from N5 to N1?

Yes. Kanjijo covers all five levels in one path, from the first N5 kanji to N1 grammar, with 35 full mock tests at the end of the levels.

How many mock tests does Kanjijo have?

35 full JLPT-style mock tests, seven for each level from N5 to N1.

Can a JLPT app replace a textbook?

For vocabulary, kanji, grammar and reading practice, Kanjijo covers the syllabus a textbook would, and it adds review timing a book cannot. Many learners still like a textbook for long grammar explanations; the two work well together.

How long does each level take in the app?

It depends on your daily time. At one new lesson per track a day and a short review, most learners move through N5 in a few months; higher levels have more material and take longer. The SRS keeps earlier levels fresh while you move on.
