Sabakoyu

A symbolic landmark of Iizaka Onsen, one of Tohoku’s leading hot spring resorts and one of the “Three Famous Hot Springs of Oshu.” It is said to have been named “Sabakoyu” after a waka poem composed by the high-ranking 12th-century monk Saigyo Hoshi when he visited the area.

Until it was rebuilt in 1993, it was widely known across Japan as the country’s oldest wooden public bathhouse. Since the reconstruction, its nostalgic atmosphere recreating its former appearance has earned widespread praise.

The hot spring water filling the granite bath is an alkaline hypotonic spring, and one of its main appeals is the luxurious experience of soaking in free-flowing water directly from the source. It is said to help with neuralgia, muscle pain, stiff shoulders, recovery from fatigue, and overall health promotion, making it ideal for soothing the fatigue of travel.

With its integrated changing room and bathing area layout, open interior with a high ceiling, and traditional style of washing yourself using water scooped from the bath instead of a shower, you can fully enjoy the essence of Japan’s long-inherited hot spring culture.
