Fukashi-Yu: Warmed Up by Steam
Fukashi-Yu is located just 100 meters down a side road from Jigoku-numa Pond. This is not a regular hot spring, but rather a place where visitors can stop by and get warmed-up by steam from the hot springs. Fukashi-Yu is a small hut built over wooden boxes that steam passes through. Visitors sit on one of the boxes and let the steam warm them to the core.
Please note that steam occasionally escapes from the edges of the box. As it is hot enough to cause burns, visitors should take care when enjoying the facilities.
Close to Fukashi-Yu is a trail that leads to the Tohoku University Botanical Gardens walking path. The trail can also be accessed from a gate just uphill from Jigoku-numa Pond.
