Overview

AI-generated overview

Remote MCP server that lets an assistant search Japanese laws, look up corporations and find official statistics, with English-normalized metadata.

What you can do
  • Search Japanese laws and regulations by keyword, returning English-normalized metadata and matched Japanese text
  • Fetch the original Japanese text of a law by law id or revision id, optionally a single article
  • Look up Japanese corporations by partial name or 13-digit corporate number
  • Search Japanese official e-Stat statistics tables by keyword and return English-keyed table metadata
When to use it
Useful when you need Japanese legal text, corporate registry details or official statistics inside an assistant session, and want English-labeled metadata while keeping the authentic Japanese source text and attribution.
Requirements
Remote streamable HTTP endpoint, no installation. No authentication or API key for the law tools. The corporation lookup needs a free National Tax Agency application ID, and the statistics search needs a free e-Stat application ID. Network access required.
Before you install
Two tools depend on free application IDs from Japanese public agencies, which you must obtain and supply. Results are Japanese-language source data with English-normalized metadata, so Japanese keywords work best. Returned legal text carries a required source attribution that should be preserved.

Installation

In SourceWeft

  1. Open Japan Data Mcp in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/app.netlify.japan-data-mcp%2Fjapan-data-mcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows
