The Ritz-Carlton, Tokyo

What the classifiers highlight

Nine floors at the top of Tokyo Midtown, one of the city's tallest towers, put this Ritz-Carlton over Roppongi's nightlife district. Forbes marks the 46th-floor spa at 21,000 square feet with a 66-foot pool, and Hinokizaka, the Japanese restaurant built around a teahouse more than a century old, with a separate room for each specialty.
