Aman Tokyo, Japan

Occupying the top six floors of Otemachi Tower with 84 suites, Aman Tokyo channels the calm of a traditional Japanese ryokan through 10-metre-high washi-paper screens, hinoki wood soaking tubs, and a 30-metre swimming pool. Opened in 2014, it consistently ranks as Japan's highest-rated urban hotel by both Conde Nast and Travel + Leisure readers, with nightly rates from $1,500 reflecting its position at the absolute pinnacle of Tokyo luxury.
