The long-established inn "Chosenkaku Kameya" in Shimosuwa Onsen, Nagano Prefecture, and the bath facility "Nagomi no Yuya Tsumugi" in the same Shimosuwa post town have entered a new business alliance, launching a new collaborative accommodation plan incorporating the "Tenko Stone Onsen Sand Bath" provided by Nagomi no Yuya Tsumugi. Through the creation of new tourism content utilizing local resources, this business aims to extend the length of stay and increase tourism consumption, while newly creating a stay-type wellness experience unique to Shimosuwa to contribute to revitalizing the bustle of the Shimosuwa post town that once flourished.
■ Background and Purpose of the Business
The Shimosuwa post town developed as a historic post town where the Nakasendo and Koshu Kaido highways intersect.
However, in recent years, with changes in tourism formats, the shift from a "pass-through type" to a "stay type" has become an issue.
In this initiative, we combine:
- A historic accommodation facility (Chosenkaku Kameya)
- Region-specific hot spring resources (Shimosuwa Onsen)
- New experience-based content (Tenko Stone Onsen Sand Bath)
By combining these, it is an attempt to reconnect the "stay culture as a historic, traditional post town" with a "new form of healing."
■ Characteristics of the Tenko Stone Onsen Sand Bath
The Tenko Stone Onsen Sand Bath provided by Nagomi no Yuya Tsumugi is a rare natural hot spring flow-through sand bath (advanced sand bath) in Japan, multiplying the precious natural ore "Tenko Stone" from Takachiho, Kyushu, with the high-quality source of Shimosuwa Onsen's famous "Tanga no Yu."
The far-infrared effect warms you gently from the core of your body, and the experience of regulating physical and mental circulation while promoting sweating is currently attracting attention as a new form of "Toji" (hot spring therapy) that meets modern people's needs for fatigue recovery and relaxation.
This accommodation plan provides a special time where guests can experience the region's new bathing culture alongside a calm stay unique to a long-established inn.
