The Shinjuku Park Tower has in some ways the most arrogant, hard-edged design of any of the skyscrapers in Nishi-Shinjuku, but it does provide any number of opportunities to rest and take on fuel. A number of floors are devoted to architectural and interior design. The atrium has free chamber-music concert on certain days. The top floors house the Park Hyatt Hotel, which has some of the best views in the city.
