The Precision of Japanese Occasion

Spaces of Purposeful Proportion

Six private event spaces — from the eight-seat Akari Board Room to the two-hundred-person Marunouchi Grand Salon — reflect the architectural precision of Kengo Kuma's original design brief. Contemporary AV technology is integrated without disturbing the building's visual language.

  • Celebrations

    Mark the moments that define a life in spaces designed to hold their weight. At Altaris Tokyo, ceremony is not performance — it is architecture, light, and the precise intelligence of omotenashi.

  • Meetings

    Conduct the conversations that shape strategy from an environment of absolute architectural restraint. Kengo Kuma's precision is the most credible context for the most consequential meetings.

  • Entertainment

    A space of purposeful restraint, designed to amplify the significance of what happens within it. From private performances to curated cultural occasions, Altaris Tokyo provides the architectural authority and the invisible team.

Reservations

Altaris is a portfolio demonstration. In a live build, this connects directly to your preferred reservations platform — whether an in-house system, a third-party engine, or a bespoke integration.
