search | Search the Japanese statutes japanlaw.org holds, in force today. A query with any Japanese in it searches the Japanese text (時間外労働, 有給休暇); one without searches the English shown for each provision, stemmed (overtime, paid leave). Results are laws whose title matches, then one result per matching art |
fetch | Read what an id from search names. A provision's id (labor-standards-act/art-36) returns it as Markdown: the Japanese text with each paragraph's English under it, every English line marked as the Ministry of Justice's translation, the Ministry's with a slip corrected, or machine translation; its add |
list_laws | Every law japanlaw.org holds: Japanese and English title, short names, kind (法律 Act, 政令 Cabinet Order, 省令 Ministerial Order…), law number, the date the text held took effect, number of articles, the share of paragraphs with English, and URLs; kinds counts them by kind. A law not in this list is not |
get_law | One law: titles, number, kind, when the text in force took effect, the texts held (versions: in force, not yet in force, no longer in force, each with the days it stands), how much of it has the Ministry's English, and this site's plain description of it — what it is for, who it applies to and who i |

For each paragraph and item, the Japanese text (textJa), its English (textEn) and whose that English is |
get_citing_provisions | Every provision in the laws japanlaw.org holds that cites the given one — the other direction from what a statute says, which no official source publishes. Each with its law, designation, the words it cites with, an id for fetch and its url; link each one you name by its fromUrl. Call it with law an |
get_definitions | The words a law defines for itself (定義語): inside that law, and only as far as each definition reaches, the word means what the statute says, not what it means in everyday speech or in another law. For each, the statute's own words (statuteJa), its reading, its English and whose that is (englishWhose |
get_amendments | A law's amendments whose changes japanlaw.org holds: the amending Act (titles, law number), the day it takes effect, whether it is in force, not yet in force or since replaced (state), how many provisions it changes, adds and removes, and its revision key. With revision — {"law": "labor-standards-ac |
