Head Sommelier, Restaurant Ryuzu (Two Michelin-starred)

Silver Star Award – Star Wine List Tokyo 2025

Brand Ambassador of VIVANT Japan

Wine is shaped twice — once by the producer, and once by the moment it is served. Temperature is what bridges those two acts. Two degrees of intent, and the bottle in the glass is no longer the wine the producer made.

At Restaurant Ryuzu, every pour is measured before it reaches the guest. This is the discipline VIVANT shares — exact in thermal control, quiet in design. It does not perform. It lets the wine speak.

From my experience at a winery in Australia, to restaurant service in France, and throughout my career to this day, what I have always valued most is delivering the producer’s vision in the best possible condition. VIVANT lets me carry that vision to every guest, every pour — from soil to glass, every time.
