This hot spring water, which flows from 1,500 meters underground, scored a maximum score of 5 out of 6 categories during the Japan Natural Hot Spring Examining Authority inspection! With a composition similar to salty seawater, it is also called “Netsu no Yu” (high temperature bath) due to the amount of cold water required to cool it down. The fact that this hot spring can be enjoyed during the colder months without any added water is also an appeal. The high-concentration carbonated spring, which even garners the attention of the medical industry, can be enjoyed as well.

This is the Ōsawa village shrine. It is said the Katori Shrine was transferred here from Sagishiro. The “Meisaichō” notes the shrine's establishment as Ōei era (1394 to 1428). This area belonged to Shimōsa Province in the middle ages, and Katori Shrine, the province's first shrine, was invited to the village as its guardian deity and built in Sagishiro. It was moved to its current ground around the Kan’ei era (1624 to 1644) due to the maintenance of the Ōushū Kaidō. According to the sign displaying date of construction (munafuda), the current main shrine was renovated in 1866. A pattern from the fabric-dyer is engraved around one side of the main shrine. It is the work of Takejiro Hasegawa who resides in Mount Asama San’ya-machi and is the city’s designated cultural property.
