Wakayama Shirahama Town
A seaside bathing paradise where an infinity pool and exceptional sauna houses come together
"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.
A natural hot spring open-air bath fed by the hotel’s own source, with three different depths to enjoy. The deepest tub is a 120 cm-deep standing bath, allowing you to experience an overwhelming soak in fresh 100% free-flowing spring water, as if your whole body were melting into the unobstructed panoramic view of the Pacific Ocean.
The superb natural hot spring Shirahama Onsen, drawn from the hotel’s own source, is offered through free-flowing bathing (continuous flow with added water) in large baths, lukewarm baths, hot baths, seasonal baths, and more. With its gentle, mildly alkaline feel, it softly cleanses old dead skin and pore impurities, letting you enjoy the smooth, moisturized beauty bath to your heart’s content.
A large foot bath with an overwhelming location, installed on a terrace overlooking the Pacific Ocean, stretching 30 m in length. Surrounded by a pleasant sea breeze and gazing at the horizon, it gently warms your body from the feet up. This superb relaxation spot is perfect for unwinding between sightseeing in Shirahama or after a sauna session.
A dry sauna located inside the men's public bath. In a compact room filled with the warmth of wood, the crisp heat gently envelops your body. It warms you deeply from within and quietly relieves daily fatigue as you sweat it out in a soothing, restorative space.
A spacious cold plunge bath in the men's public bath area. Clear, refreshing cold water welcomes your overheated body after the sauna. Although it is tap water, it has no unpleasant sting, and its mellow coolness gently wraps around the entire body, tightening it pleasantly.
[Day-use bathing] 13:00–20:00 (last admission), [Barrel sauna] 09:00–21:00 (day-use visits from 13:00–), [SAUNA HOUSE on] 09:00–22:00 (reservation required by 15:00 the day before)
