AIC Tax works in English and both simplified and traditional Chinese, with its head office in Osaka and a Tokyo office in Minami-Aoyama. Notably for founders, it lists corporate bank account opening among its services — a step many tax firms leave to the client, and one that is often the hardest part of setting up without a track record in Japan.
Its range runs from bookkeeping guidance through to tax audit representation. Visa work is not mentioned. The site refers to a paid consultation service but publishes no figures, and states no founding year or client numbers.
