Why we built this site

Social media and word of mouth are full of “plausible” tax talk. Some of it is wrong, some is only half right, and believing it blindly has led to real cases of additional tax and penalties.

Yet there were almost no places that verify such rumors back to their sources (statutes, circulars, and official NTA information) and go beyond “no” to show “what to do instead.” “Zeihonto?” was built to fill that gap — a fact-checking site reviewed by a licensed Japanese tax accountant (zeirishi).

It uses cookies to collect information such as the URL of the pages you view, the referring page, your browser type, and the date and time of access. This site is configured not to send query strings (the part after “?”) in those URLs and referrers, but this does not guarantee that an individual visitor cannot be identified.
