Good to Know
Aman Tokyo
- Musashi by Aman is the hardest reservation in the hotel by far — request it when you book your room, not after arrival, given how few counter seats it holds each night.
- Aman Tokyo shares its Kerry Hill design lineage with Aman Kyoto and Amanpuri; guests who know either property will recognise the material language immediately.
- Otemachi is a business district that empties out on weekends and after dark — quiet in a way that suits the hotel's register, but plan an evening in Ginza (a five-minute taxi) if you want street-level energy.
- The onsen-style spa pool is naturally lit and genuinely rare for central Tokyo — worth booking a treatment around daylight hours rather than in the evening.
The Siam
- Transfers are via private twin-engine seaplane, private speedboat, or helicopter coordinated directly with resort operations.
- A dedicated personal butler (Barefoot Butler / Mr./Ms. Friday) oversees every detail from unpacking to private island picnics.
- Pack lightweight linen and swimwear; barefoot luxury culture is celebrated across the islands.
