Park Hyatt Tokyo occupies the 39th to 52nd floors of Shinjuku Park Tower, the Pritzker-winning Kenzo Tange building that has anchored West Shinjuku since the early 1990s. The hotel reopened in 2025 after a full top-to-bottom renovation, returning with the same set of rooms, restaurants, and bars that built its reputation.
There are 171 rooms in total, including 29 suites. The interiors are set up to feel residential rather than hotel-like: bespoke furnishings, curated art, and floor-to-ceiling windows over the city throughout. Clear-day views across to Mount Fuji from the higher suites.
The 52nd-floor New York Grill is the headline restaurant, with live jazz, an open kitchen, and 360-degree skyline views. Kozue handles modern Japanese on the 40th, and Girandole, the brasserie space, reopened under Alain Ducasse after the renovation. The Library on the 41st floor holds over 2,000 books originally curated by interior designer John Morford.
