The hardest part of Japanese isn't learning it.
It's knowing if you got it right β and having a reason to keep going.
That's exactly what Nihongo Diary is for. Write a diary in Japanese, get it corrected instantly, and keep going alongside other learners.

Obie: 3-day streak! Keep going πΎ
You can study Japanese for years and still freeze the moment you try to use it.
Input is everywhere β textbooks, apps, videos, flashcards. Output is the problem. The moment you try to actually produce Japanese, two things stop you:
- β1. You write somethingβ¦ but you have no idea if it's right. No one's there to check. So the mistake just becomes a habit.
- β2. You promise yourself you'll practice every dayβ¦ and alone, you quietly stop. Not because you're lazy. Because no one's doing it with you.
This is the output wall. It isn't a talent problem or a motivation problem. It's that the one skill that matters most β output β is the one thing no app ever really helped you with.
So we built Nihongo Diary around those exact two problems.
Not another way to study. A way to finally output β and get the two things that were always missing.
01
Get it corrected
Write in Japanese. The moment you finish, you get it back β corrected. That's the answer-check that was always missing.
02
You're not doing it alone
See real diaries from other learners. React, comment, follow. Share your own and receive peer corrections on top of AI ones β two layers of feedback, from the machine and from people who've been where you are. Their mistakes become your lessons. Your streak has witnesses.
Everything you need to output β nothing you don't.
Instant AI correction
Corrected version, natural rewrite, why-it-was-wrong, and the vocab you used. Every single entry.

What Japanese learners say
βI've kept a little Japanese diary for three months β writing every day and getting it corrected. It's the best way to learn everyday words and practice grammar.β

writing daily
βI'd wanted to do daily writing practice and keep a journal. This solved two problems at once.β

keeping a streak
βSuch a cool idea. I love the order β original, natural rewrite, teacher's notes, key mistakes, vocab, then a practice sentence.β
Jamie πΊπΈ
diary regular
I'm a Japanese teacher. But before that, I was an English learner who hit the exact wall I just described.
I learned the hard way that real progress comes down to three things: input, output, repeat. Input was easy. Output was where I got stuck β because I could never check if what I produced was actually right, and alone, I always quit.
The one thing I managed to keep doing was writing a diary. And I kept thinking: if only I could record it by voice too, and if only someone could check it the moment I wrote it.
So I built the thing I always wanted β for my own students, and for every learner stuck at the same wall. A current teacher who was once a learner, making the tool he actually needed. That's Nihongo Diary.
