The Aman Spa is the largest luxury spa in Tokyo and runs on the same operating standard as the rest of the Aman group — onsen-style baths drawn from natural mineral water, a thirty-metre pool that runs along the 34th-floor glass, and the 2026 Intelligent Movement programme that pairs Thai stretching with modern physical therapy. Treatments are taken in two-hour slots that are the real difference between a spa visit and a treatment.
Book the Spa for Two private suite for the anniversary or the long weekend, take the bath ritual before the treatment, and finish with the late-afternoon pool. Open to non-resident guests by reservation — the answer when the hotel itself is sold out.
The city's spa, by some distance.
