Japan Corporate Data MCP server
by yamariki-hub
Look up Japanese company details, financials, patents, subsidies and government statistics right inside your AI chat.
This is a small helper that lets your AI pull official information about Japanese companies from government websites. You ask a question in plain words, and your AI fetches the answer from public Japanese government data sources. It is handy if you work with Japanese companies, do research, or need company facts without opening five different websites.
What is an MCP server? The 30-second version
On its own, your AI can only chat with you using what it already learned. An MCP server is a small helper program that gives your AI a new skill or a connection to an outside service. This one connects your AI to Japanese government data services like gBizINFO, EDINET and e-Stat. Once it is set up, your AI can look things up there for you whenever you ask.
What this MCP server does
You type a question about a Japanese company, a patent, a subsidy or a statistic. Your AI sends that request to this helper program running on your computer. The helper talks to the official government data services and brings the answer back. Your AI then shows you the result in the chat, in normal sentences or a short list. You do not need to visit any of those government websites yourself.

What it gives back to you
You get back plain answers in the chat: company names, addresses, financial numbers, patent lists, subsidy records or statistics. Sometimes it is a short summary, sometimes a small table or bullet list. The information comes straight from the government data services, so it is the official version. Nothing is changed on those sites; this helper only reads.
