About

Seven years building products and brand systems in Tokyo.

Four years leading product design at Enjin as the sole designer across three verticals: Career, Forum, and Community. Ran 20+ user interviews, managed the design intern team, and built an Adobe XD component library that cut design-to-engineering handoff friction. Owned end-to-end from information architecture through shipped UI.

Currently at Miraidukuri Company, a Tokyo cultural-tourism company, leading brand and web work.

On the side, shipping AI-native tooling. Three MCP servers published to npm with 2,000+ monthly downloads, growing. A Chrome extension on the Web Store. Several web apps. All designed and built with AI-assisted development.

Product design is not about aesthetics. It is about judgment. What to build, what to cut, what to leave alone.
