Small, free tools for the questions that come up before every trip to Japan. They run in your browser — nothing you type is sent anywhere — and each one explains the rule behind it with a link to the official source.
The budget calculator starts from the Japan Tourism Agency’s 2025 spending survey, the climate tool from the Japan Meteorological Agency’s 30-year averages, and the holiday list from the Cabinet Office. The tax-free and baggage checkers encode the rules published by the Japan Tourism Agency and JR Central, including the tax-refund system that starts on 1 November 2026. When a rule changes, the tool is updated and the change is noted on the news page. No tool asks for your name, email or card, and none uses cookies; the checklist saves your ticks in your own browser only.
