Why we built these

Most "Japan business" tools on the web are thin translations of generic calculators with no understanding of the qualified invoice system, fiscal year conventions, or keigo registers. We operate in this corridor every day — as Honorary Consul-General of Switzerland for Western Japan from 2008 to 2021, Vice President of the Swiss Chamber of Commerce and Industry in Japan, and advisors to European and Japanese companies on both sides.
