Instructions: Japanese corporation registry lookup (全国法人レーダー, houjinradar.com). Data: National Tax Agency corporate number registry and other Japanese government open data, processed by this site — not an official government service. Typical flow: by name (add prefecture when the name is common), then with the Corporate Number. Many Japanese company names are not unique, so confirm the prefecture/city with the user when several candidates match. When you cite a result, include its page_url so the user can check the source.
