Living in Japan as a foreign resident means a constant stream of official paperwork — in a language most expats can't read. Visa renewals, tax filings, health insurance notices, municipal documents: they keep coming, and the consequences of missing deadlines are real.
Jozu is the app we built because we needed it ourselves. It's an AI-powered document management platform that translates official Japanese paperwork, alerts you to deadlines, and keeps everything organised in one place.
Built on Next.js with a React frontend, Jozu integrates Claude AI for accurate document translation and categorisation. The system understands the context of Japanese bureaucracy — not just the words, but what the document means for your life in Japan.
