Japan Company Leads Finder MCP — 日本企業リード検索
B2B lead generation for the Japanese market, powered by official government data.
Search over 1 million Japanese companies by size, capital, location, founding year — and a signal you won't find anywhere else: government subsidy history. Built on METI's official gBizINFO database. 100% legal, no scraping, no stale data.
Why this server?
Prospecting in Japan is notoriously hard for AI agents: no LinkedIn culture, Japanese-only registries, fragmented data. This server gives your sales agent direct access to the government's own company database — including representative names, employee counts, business summaries, and public funding records.
The killer signal: a company that received an IT-adoption or facility-investment subsidy has budget, ambition, and a documented modernization agenda. That's a warm lead, certified by the government.
Tools
search_companies
Filter by prefecture, employee count, capital, founding year, and subsidy history. Returns corporate numbers for drill-down.

Government contract track record — for supplier vetting and public-sector sales intelligence.
Example queries your agent can now answer
- "Build a list of Tokyo companies, 10–100 employees, that received government subsidies — with CEO names and websites"
- 「大阪府の製造業で設備投資系の補助金を受給した会社を20社、代表者名付きでリストaップして」
- "Vet this supplier: what's their government contract history?"
Data source & freshness
Official gBizINFO REST API (Ministry of Economy, Trade and Industry, Japan), fetched live on every call.
Pricing
Pay per tool call ($0.02). One search, profile, subsidy, or procurement lookup = one event. A 50-company lead list with full profiles ≈ $1.
