The Signature Experience

A Private
Omakase Journey

Behind a sliding hinoki door, a single chef prepares twenty courses for eight guests. The fish arrives that morning from Toyosu. The rice is seasoned by hand. The pacing is yours alone.

Each seat is paired with a flight of rare junmai daiginjō, poured from cedar masu beside handcrafted Bizen-yaki ceramics. Two seatings nightly. Reservations confirmed personally.

The Open-Air Lounge

Cocktails Beneath
a Floating Sky

Step beyond the glass into the night air. Fire bowls reflect across the infinity edge. Paper lanterns sway in the updraft. A brass-clad bar pours yuzu negronis, smoked highballs and seventy years of Japanese whisky.

The Tower

A Private Elevator
to the Sky

Kōgan occupies the entire 45th floor of the Asakawa Tower — a monolith of smoked glass rising 220 meters above the harbor district. Arrival is by valet at the marble porte-cochère, then a single brass elevator carries you, silently, past forty-four floors of darkness.
