Yuika

Japanese mail, explained

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Photograph any Japanese letter, bill or form. Yuika tells you what it is, what to do, by when and how much — then tracks the deadline. 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 10 free scans every month. Upgrade to Yuika Premium for unlimited scans (auto-renewing subscription via the App Store). Guidance only — not legal or tax advice. Always verify amounts and dates against the original. YUIKA PREMIUM Auto-renewing subscription: Yuika Premium Monthly (1 month) and Yuika Premium Yearly (1 year). Price is shown in the app before purchase and charged to your Apple ID.
