About

This free tool is published by GuroWorks, a small independent publisher of travel and digital-business guides. It is not affiliated with the Government of Japan, Japan Customs, JTA, NTA or JNTO.

How this site is made: content is drafted with AI assistance, then checked line by line against the official sources listed on each page. The check date is shown on every page. We do not publish reviews, testimonials or experience claims.

Money: we sell two paid products of our own (linked as such). The site has no ads and no affiliate links right now. If that changes, they will be clearly labeled.

Corrections: spotted an error? Rules change. Please check the official source first, and tell us via our Gumroad profile page.
