Query official Japanese e-Stat databases inside Claude Desktop

`search_japan_statistics` lets you query the official Japanese government database directly from your Claude Desktop chat bar. When you type a keyword like population or GDP, Claude Desktop uses e-Stat tools to retrieve the matching table IDs and survey dates instantly. This e-Stat search tool bypasses the clunky Japanese government web portal entirely inside your Claude Desktop workspace. Your Claude Desktop agent scans the e-Stat metadata to pinpoint the exact dataset you need before pulling any raw numbers.

Pull raw e-Stat tables directly into your Claude Desktop chat

`get_japan_stats_data` extracts the actual Japanese economic numbers, time periods, and regional values directly into your Claude Desktop session. This tool turns raw e-Stat JSON payloads into clean, structured data inside Claude Desktop. You don't have to download Japanese CSV files when Claude Desktop formats the e-Stat payload into clean markdown tables on the fly. Your Claude Desktop agent processes the e-Stat schema automatically.

Run local Japanese data pipelines with this Claude Desktop MCP Server

Claude Desktop executes `get_japan_stats_data` and `search_japan_statistics` as local subprocesses to keep your Japanese statistical queries completely private. This setup means your Claude Desktop workspace can immediately ingest the fetched e-Stat statistics without exposing your local scripts to the public internet. You get a direct, authenticated pipeline to Japan's e-Stat database inside Claude Desktop. The Claude Desktop tool integration handles the connection, leaving you to focus on analyzing Japanese economic trends.
