Founder, FitSync

As an Operator

As CEO of AlphaEdge, I run a business built around R&D in humanoid robot motion control, AI implementation, and multilingual marketing. The core is the R&D program (Human Movement × Robotics) and FitSync (a personal training service with five Tokyo gyms — Roppongi, Shinjuku, Shibuya, Ginza, Azabu-Juban — plus on-site lessons). On top of that, we run an AI-driven YouTube publishing pipeline and inbound marketing for Chinese-speaking audiences — all implemented in-house.

Operating Philosophy

Not an executive who can use AI — an executive who actually puts AI on the floor.

AI conversations spread quickly in Japan, but most of the discussion still splits into "users" and "builders." Very few operators are embedding AI directly into the daily workflow of a real business.

AlphaEdge keeps proving that AI-implemented operations are possible — through automated YouTube content, and a fitness pipeline that actually runs every day.
