Japanese law in Gemini

Set it up

1. 1

   In the Gemini web app, open Connected Apps settings and add a custom app with its MCP server URL:

   MCP server URLCopy

   https://japanlaw.org/mcp

2. 2

   Once connected it is available in the web and phone apps. Type @ and pick it to make sure Gemini uses it.

3. 3

   In Gemini CLI, one command adds it for every project:

   terminalCopy

   gemini mcp add --transport http --scope user japanlaw https://japanlaw.org/mcp

Before you start

• Google offers custom connected apps only in English for now, with Gemini Apps Activity (Keep Activity) on, and not in every country or plan; Google's help page has the current conditions.
• Custom apps are added in the web app; they then work in the phone app too.

Then ask

• Under Japanese law, how many hours of overtime can my employer ask of me in a month? Quote the article.
• What does Article 36 of the Labor Standards Act say? Show the Japanese and say whose English it is.
• I'm renting an apartment in Tokyo. When can the landlord refuse to renew the lease?

What Gemini can do with it

search

Finds provisions, laws and defined terms by Japanese or English words, in every law held or in one, best match first. Each result has an id for fetch and the page's URL.

fetch

Reads what a search result's id names: a provision in Japanese with its English, each line marked as the Ministry's translation or machine translation — in force, or as it stood on a day; or a law's overview and outline.

list_laws

Every law japanlaw.org holds: title, number, kind, date of the text in force and how much of it has English.

get_law

One law: what it is for, who it binds and who it does not — its exceptions and how it is enforced on request — the texts of it held, earlier and to come, and its chapters, or what is under one of them.

get_provision

An article, paragraph or item by its citation — 第三十六条第二項, Article 36(2) or art-36/par-2 — in Japanese and English, with what it cites, the terms it defines and its URLs: in force, or as it stood on a day. Shown as a card where the app can draw one.

get_citing_provisions

Every provision in the collection that cites the one given, with links. No official source publishes this direction.

get_definitions

The words a law defines for itself — 労働者, 賃金 — each with the statute's own definition, its English and whose that is, a plain explanation, where it is defined and how far it reaches. Given a provision, the definitions that apply in it and the legal vocabulary it uses.

get_amendments

A law's amendments: the amending Act, its number, the day it takes effect and whether it is in force. Given one, every provision it changes, before and after, in Japanese and English, each English marked as the Ministry's or machine translation.
