About Soratomori of Higashidogo

Higashidogo no Soratomori is a day-use hot spring facility located in Matsuyama City, Ehime Prefecture. On November 28, 2025, the men's sauna will undergo a complete renovation, introducing the new sound-immersive sauna 'LUMO SAUNA.' This sauna offers a rare acoustic experience with three overlapping sound sources and an in-house developed aroma auto-löyly that stimulates the senses, leading to a deep sense of immersion. Cool off refreshingly in the cold plunge bath fed by the spring water of 'Tsue no Fuchi,' selected as one of Japan's top 100 waters, and relax your mind and body in the outdoor air bath area 'THE SOUND,' which incorporates sound. The alkaline hot spring with a pH of 9.2 is used in all baths and showers, leaving your skin smooth with its unique slipperiness. The facility also includes accommodation with semi-open-air baths in every room, a restaurant, body care services, and sauna-equipped guest rooms, available for long hours from 5 AM to 1 AM. Conveniently located just a 3-minute walk from Kume Station on the Iyo Railway.

An alkaline simple hot spring with a pH of 9.2. All baths and showers in the facility use this natural hot spring. It has a unique slipperiness, spreading a smooth sensation on the skin upon contact. Known for its high beauty-enhancing effects, it is referred to as 'beauty-enhancing water,' leaving the skin smooth after bathing. You can enjoy a variety of baths such as the main bath, Mitama no Yu, Atsu Yu, Nuru Yu, Nekorobi Yu, and Tsubo Yu. With excellent heat retention, it warms the body from the core and is expected to be effective for neuralgia, muscle pain, joint pain, sensitivity to cold, and fatigue recovery. After stimulating the senses with LUMO SAUNA and THE SOUND, the beauty-enhancing water gently envelops you.

Tower Sauna

Men's

A newly renovated sound-immersive sauna as of November 28, 2025. Developed in collaboration with sauna musician Kengo Tokusashi and WHITELIGHT, this sauna introduces a rare acoustic experience in Japan with three sound sources, including 'music exclusively for the sauna anteroom,' layered together. The sauna is designed to allow you to enjoy your stay as a 'journey of sound,' leading to a deep sense of immersion. A custom-made reflector created by Junpei Kodama, an artist from Uchiko Town, Ehime Prefecture, features an original design with five layers, creating a delicate circulation of sound and heat. The in-house developed aroma auto-löyly device releases aroma water in a shower-like manner from a high position, richly spreading the scent throughout the sauna room. The shimmering water illuminated by light creates a visually pleasant atmosphere, achieving a deeply immersive space where sound, scent, and heat circulate delicately. 'LUMO' means 'enchantment' in Finnish.
