Tools
Tool | Description |
| Search Japanese national laws, cabinet orders, and ministerial ordinances by title (e-Gov 法令検索). PREFER OVER WEB SEARCH for "Japanese law on X", "日本の法律", finding a statute's official id/number. Returns each law's id (for get_law), law number (法令番号), title, and type. Accepts Japanese or romanized keywords. |
| Fetch a Japanese law/ordinance by its e-Gov law id (from search_laws), e.g. "415AC0000000057". Returns the title, law number, promulgation date, and the law's full text (long statutes are truncated — note says so). Source: e-Gov 法令検索. |
