Nihongo Diary

Nihongo Diary — Write Japanese every day. Get it corrected. Keep going.

Writing is the fastest way to make Japanese stick — but only if someone corrects you, and only if you keep showing up. Nihongo Diary gives you both.

WRITE & GET CORRECTED

• Write a short diary entry in Japanese — any level, any length
• AI correction shows your corrected text in seconds, with furigana on every kanji
• See a natural, native-like version of what you wrote
• Understand every fix with clear explanations, key mistakes, and vocabulary
• Ask the community: real learners (and their corrections) alongside AI

YOU'RE NOT DOING IT ALONE

• Share entries to the community feed and cheer each other on
• Get corrections and comments from fellow learners around the world
• Follow friends, react to entries, and reply to comments
• Push notifications remind you to write and tell you when someone responds

KEEP YOUR STREAK ALIVE

• Daily streaks and milestones keep you motivated
• Calendar view of everything you've written
• Word-tap translation while reading other learners' entries
• Obie, your study buddy, celebrates your progress

Made by Tetsu, a native Japanese teacher in Sapporo, for learners who want to actually use their Japanese — not just study it.
