Saki-no-Yu: A Historic Open-Air Bath Beside the Pacific
Among Shirahama’s many hot springs, Saki-no-Yu is one of the most famous. It is the only surviving bathing site among the historic “Seven Hot Springs of Yusaki,” known as Yusaki Nana-yu, and is regarded as one of the symbols of Shirahama Onsen.
The open-air bath is built directly on the rocky shoreline. With the vast Pacific Ocean immediately in front of you, the experience can feel as though you are bathing in the ocean itself. Waves crash against the rocks nearby, and the sound of the surf becomes part of the bathing experience.
When the weather is rough, waves can even splash into the bathing area, adding an extraordinary sense of connection with nature. Few hot springs in Japan offer such a dramatic seaside setting.
A Hot Spring with More Than 1,300 Years of History
Saki-no-Yu is mentioned in the Nihon Shoki, one of Japan’s oldest historical chronicles, and is closely connected with Shirahama’s approximately 1,350-year history as a hot spring destination.
As you soak in the water and look toward the horizon, passing boats and the endless Pacific Ocean create a scene that may not have changed dramatically since ancient times.
The spring is a sodium-chloride hot spring with a source temperature of approximately 78°C. Its mineral content provides a warming effect, helping the body remain warm even after leaving the bath. The distinctive atmosphere created by the combination of the sea breeze and the scent of sulfur adds to the authentic onsen experience.
An Open-Air Bath Surrounded by Nature
Because the water from Saki-no-Yu flows directly toward the sea, soap and shampoo cannot be used. Rather than being a disadvantage, this restriction highlights the natural character of the bathing experience.
The bath is designed to let visitors experience the hot spring in an environment that is closely connected to the surrounding landscape. In the men’s bathing area, there are few obstructions to the view, creating an extraordinary feeling of bathing while looking out across the open ocean.
At sunset, the experience becomes particularly memorable. The setting sun colors the surface of the Pacific in shades of orange and red, creating a beautiful contrast with the surrounding rocks and the warm waters of the hot spring.
Shirasuna Open-Air Bath and Shirasuna Foot Bath
Located beside Shirarahama Beach, the Shirasuna Open-Air Bath is another popular place to experience Shirahama’s distinctive combination of beach and hot spring culture.

During the summer season, visitors can enjoy the bath wearing swimsuits, making it particularly convenient for families and groups. It is possible to go from the beach directly to the hot spring, combining swimming and bathing in one easy outing.
Enjoy It as a Foot Bath During the Cooler Seasons

The spring water is adjusted seasonally so that it remains comfortable throughout the year. This makes the facility an easy and accessible way for visitors to experience Shirahama’s hot spring culture without committing to a full bath.
