Ehime Matsuyama City
Himehiko Onsen is a day-use bathing facility in Matsuyama, Ehime Prefecture, boasting natural hot spring water that gushes from 1,000 meters underground. In addition to its high-quality, slightly slippery and velvety onsen water, the facility has well-equipped sauna amenities. The dry sauna features regular auto löyly that creates intense heat waves beloved by sauna enthusiasts. The cold plunge bath uses onsen water cooled by a chiller and is characterized by a mellow feel on the skin thanks to submerged binchotan charcoal. Private family baths are also equipped with saunas and cold plunge baths.
TypeNatural Hot Spring
Natural hot spring water that rises from 1,000 meters underground. The spring is alkaline and popular as a beauty bath that leaves the skin slippery and smooth. The large public bath area features a variety of tubs, including a walking bath and a microbubble open-air bath. In addition, the 24-hour family baths (20 rooms in total) are supplied with natural hot spring water, and some rooms include private saunas, cold plunge baths, and open-air baths.
Sauna TypeDry Sauna
Stove Typefar_infrared
A three-tier tower-style dry sauna. Air temperature is around 85°C–90°C, but it is notable for an auto löyly that operates three times every 40 minutes in one-minute intervals. The moment water drops, hot steam fills the room, sharply raising the perceived temperature and drawing out a torrent of sweat. Every Sunday they hold events such as Extra Hot Sauna Day, when the set temperature is increased. A 50°C–60°C steam sauna is also provided.
Water Qualityhot_spring
One of Himehiko Onsen's major attractions is the cold plunge bath that uses high-quality natural onsen water cooled with a chiller. Binchotan charcoal is submerged in the bath, and combined with the spring minerals it produces an exceptionally mellow, skin-friendly texture. Water temperature is about 15°C–18°C, gently but effectively cooling a body heated by an intense sauna. Water depth is ample at 40–60 cm.
