Kabuken, our platform for the financials of Japanese listed companies, is now listed in Anthropic's Claude connector directory.

Add it to Claude, then ask about a Japanese company in plain language. The figures come from official EDINET filings, the disclosure system of Japan's Financial Services Agency. For each figure, Kabuken returns the source filing. Labels are in English and Japanese.

You can look up financial statements, business and geographic segments, major shareholders and the filing list for a company. You can compare up to five companies, screen by ROE, ROA, operating margin, current ratio and debt-to-equity, and read industry overviews.

Example, fiscal year ended 31 March 2026: Toyota revenue of ¥50.68 trillion, operating income of ¥3.77 trillion, and a dividend of ¥95 per share (¥90 the year before).

The connector is read-only. It does not provide stock prices or investment advice. Coverage has been validated for TOPIX-100 companies; other listed companies come through the same pipeline.

It works in Claude on the web and mobile, Claude Desktop, Claude Code and the Claude API, through the Kabuken MCP server. Sign in with Google or email.
