Not the hardest way (no punishing immersion) and not the gamiest (no vocabulary-only streak app). InitialJ gamifies the repetitive parts — reviews, streaks, an evolving character — so studying never feels like a grind, while every lesson runs on real spaced-repetition science. Kanji, vocabulary, grammar, and reading, mapped from N5 to N1.

N5 is free. On the monthly plan, complete the study goal shown in the app and your next month is free. The displayed price is the amount you pay.

Common questions

Clear answers, before you commit.

Can I learn Japanese in English with InitialJ?

Yes. InitialJ supports English meanings, accepted answers, grammar practice, dictionary pages, and JLPT reviews.

What makes InitialJ different from a kanji-only study app?

InitialJ covers kanji and vocabulary with SRS, then connects them to JLPT N5 to N1 grammar, reading, dictionary pages, and mock exams.

Do I need to create an account before using the app?

No. You can browse and study in temporary mode. Creating an account saves progress across devices and protects it if browser data is cleared.

What does SRS mean?

SRS means spaced repetition system. Items are reviewed after increasing intervals, so difficult kanji return sooner and mastered items appear less often.

Start now. Save progress when it matters.

You can use InitialJ immediately in temporary mode. After lessons, the app will remind you that an account protects your SRS progress across devices.
