Summary

This connects Claude to 14 Japanese government and financial data sources through 22 MCP tools. You get TDnet corporate disclosures, EDINET institutional holdings, e-Stat economic indicators, J-Quants market data, BOJ tankan sentiment surveys, and JPX investor flow breakdowns. The standout tools are japan_briefing for daily market snapshots and company_intelligence for cross-source analysis that pulls profile, financials, stock prices, disclosures, and macro context in one call. It includes stock price histories with moving averages, sector summaries across 17 industry classifications, and AI interpretation through Gemini. Responses are cached intelligently by source freshness, from 5 minutes for real-time disclosures to 24 hours for corporate registry data. Useful if you're building agents that need structured access to Japanese corporate and economic information without stitching together multiple API clients.
