## What is Yuika?

Yuika turns Japanese administrative mail into clear action.

Living in Japan without fluent Japanese means a constant stream of dense letters from city hall, health insurance, tax offices, utilities and landlords. Google Translate can read the words — Yuika tells you what the document means and what you should do next.

SCAN ANY DOCUMENT
Take a photo of a letter, bill or form. Yuika classifies it, summarises it in plain English, extracts the deadline and amount, and lists concrete next steps.

TRACK DEADLINES
Every scan lands in your tracker. Overdue and due-soon items surface first so you never miss a payment or reply window.

GLOSSARY ON THE PAGE
Key Japanese terms from the document are explained in context — not a generic dictionary dump.

LIVING-IN-JAPAN GUIDES
Short guides on residence cards, My Number, health insurance, pensions and more, kept current from official .go.jp sources.

PRIVATE BY DESIGN
Your documents stay in your account. Delete any document, or delete your whole account, any time.

FREE TO START
