Enjoy the Famous Shirahama Onsen
One of the hotel’s greatest attractions is its wide variety of hot spring facilities. Guests can enjoy natural hot spring water from the hotel’s own source, flowing directly into the baths. The water is classified as a sodium-chloride and bicarbonate spring and is known for its smooth, gentle texture.
Shirahama Onsen has long been appreciated for its relaxing qualities. Bathing in the warm mineral-rich water is an excellent way to unwind after sightseeing and enjoy a traditional Japanese hot spring experience.
San-dan no Yu Outdoor Bath
The popular San-dan no Yu outdoor bath offers an extraordinary bathing experience overlooking the Pacific Ocean. One of its distinctive features is a standing bath approximately 120 centimeters deep, allowing guests to soak while standing and enjoy an unobstructed view of the ocean directly in front of them.
The bath is divided into three different depths, allowing visitors to choose the bathing style that suits them best. Feeling the sea breeze and listening to the sound of the waves while relaxing in the hot spring is a uniquely luxurious experience that can only be enjoyed in Shirahama.
Umi no Yu Large Public Bath

Nami no Yu Bath
Nami no Yu has been designed with accessibility in mind, making it easier for guests who may have difficulty walking or standing to enjoy the hot springs comfortably. Large windows offer beautiful views of the Pacific Ocean, creating a peaceful environment in which to relax.
Relax at the Infinity Foot Bath
One of Hotel Seamore’s signature attractions is its approximately 30-meter-long infinity foot bath. Located on a terrace overlooking the Pacific Ocean, the foot bath creates the impression that the water stretches seamlessly toward the horizon.
Guests can soak their feet while enjoying the sea breeze and panoramic ocean views. The foot bath is also a popular place to take a break or meet friends and family.
At sunset, the experience becomes especially spectacular. As the sun sinks below the horizon, the ocean is illuminated in brilliant shades of orange, creating a memorable and romantic scene.
Infinity Pool and Sauna with Ocean Views
The hotel also features a 32-meter-long infinity pool. Designed so that the surface of the pool appears to merge with the ocean beyond it, the pool provides a unique sensation of being surrounded by the sea.
During the summer season, the pool operates as a regular swimming pool, while in spring and autumn it can be enjoyed as a heated pool. A barrel-shaped sauna is also located beside the pool, allowing guests to relax while looking out over the Pacific Ocean.
Shirahama Underwater Observation Tower “Coral Princess”
Approximately 100 meters offshore from Hotel Seamore stands the Shirahama Underwater Observation Tower, known as “Coral Princess.” This is one of Shirahama’s distinctive marine attractions.
The observation tower is approximately 18 meters high, with viewing areas extending to around 8 meters below sea level. Visitors descend a spiral staircase beneath the surface and can observe the underwater world through 12 round viewing windows.
Around 30 species of fish, including black sea bream, rudderfish, rockfish, and butterflyfish, can be seen swimming naturally in the surrounding waters. The experience feels almost like taking a walk beneath the sea.
The facility originally opened in 1970 as the world’s first underwater observation tower. The current tower is the second generation, rebuilt in 1988. Its distinctive retro atmosphere adds another element of charm and makes it a memorable attraction for visitors to Shirahama.
