The Spa at Mandarin Oriental, Tokyo
The hotel’s clean lines and glossy flourishes extend to the gorgeous spa. With male and female bathing pools, an amethyst crystal steam room, a sauna with a million-dollar Tokyo view, and treatments that verge on out-of-body incredible, this place is supremely pampering. Every session starts with a soothing foot-bath ritual and a consultation. The Oriental Harmony treatment is over-the-top, with two therapists working together to sooth, replenish, and balance skin with a body scrub and a stimulating massage. There are only four treatment rooms here, which means you should book your session well in advance-and also that the vibe is beautifully intimate.
