A seaside bathing paradise where an infinity pool and exceptional sauna houses come together

Wakayama Shirahama Town

"SHIRAHAMA KEY TERRACE HOTEL SEAMORE" is a stylish resort complex hotel in Shirahama Town, Nishimuro District, Wakayama Prefecture, overlooking the Pacific Ocean. Guests can fully enjoy the hotel’s own hot spring source from Shirahama Onsen, one of Japan’s Three Ancient Hot Springs, through facilities such as the 120 cm-deep standing open-air bath "Sandan no Yu," which blends with the sea right before your eyes, and the powerful 30 m-long "Infinity Foot Bath." In addition, the 2023 renovation added a barrel sauna on the poolside scented with Japanese cedar and the fully private sauna house "SAUNA HOUSE on." Together with the dry sauna in the main bath area for men only, it offers three distinct and exceptional sauna experiences.
