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 the Honorary Swiss Consul General for Western Japan (14 years), as Vice President of the Swiss Chamber of Commerce, and as advisors to European and Japanese companies on both sides.
