Zero Japanese to JLPT N5 in 100 days

Learning Japanese alone usually fails the same way: the material is out there, but it is scattered across a dozen tabs and nothing tells you what to do on Tuesday. Michi is one ordered path. Open day 1, do what it says, come back tomorrow.

💼

Working in Japan

N5 is the first credential that shows an employer or a visa officer you are serious about the language. It is the honest starting line for a career move.

✈️

Moving to Japan

Reading a train sign, a menu or a form is the difference between visiting and living there. Kana comes first here for exactly that reason.

🎬

Anime & J-drama fans

You already hear the language every week. This turns passive listening into the moment a line lands before the subtitle does.

🌱

Absolute beginners

Day 1 teaches your first hiragana character. No prior study assumed, and no romaji crutch — the first fortnight gets you reading kana properly.

📅

Anyone with an exam date

Weekly checkpoints and three full mock exams tell you whether you are actually on track — instead of finding out on the day.

🙏

People who value credit

Michi is built on free teachers, dictionaries and datasets. All 67 are named with their licence, right where their work appears.

The safest AI learning for children

Trust is the whole point. We designed Gurukin so parents never have to worry about what their child sees.

  • Children never talk to an open, unfiltered chatbot.
  • Every lesson comes from approved curriculum and is human-reviewed.
  • Built for COPPA (US) and the DPDP Act (India); minimal data, verifiable parent consent.
  • No ads. No selling data. No real-money purchases by kids.
  • Wrong answers are met with encouragement — never punishment.
