Why this site exists
I built Furusato Calculator because, when I first arrived in Japan, finding English-language support to understand Furusato Nozei was surprisingly difficult. I wanted to make the system clearer and give other residents the practical starting point I wish I had.
Independence and affiliate disclosure
The calculator does not depend on a donation portal. Some outbound portal links are affiliate links and are marked as sponsored in the page markup. The site may receive a commission at no additional cost to the visitor. Affiliate relationships do not change the calculated result.
