Japan Business Data

Overview

Japan Business Data is a Model Context Protocol server that normalizes and romanizes Japanese addresses, looks up postal codes, and counts Japanese business days. It integrates directly into AI assistants as callable tools, making it easy to handle Japan-specific address and calendar operations programmatically.

The server runs as a remote endpoint at https://japan-business-data.mcpize.run, requiring only an API key for authentication. No local installation is needed—simply point your MCP client to the endpoint and you're ready to go. The current release is v0.1.0, available from https://mcpize.com/mcp/japan-business-data.

Japan Business Data is listed in the Development category and works with Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and other MCP clients. If you maintain this server, claim your listing to verify ownership and keep information up to date.
