Ikoi no Yakata Hot in Yanaizu

This is a roadside complex rather than a bathhouse. There is no bath to soak in, but there is a large walking footbath named 湯足里, free to use and themed around the hot springs of the surrounding towns and villages. Around it are a souvenir shop, a food corner known for Yanaizu sauce katsudon, and the Yanaizu Jomon museum next door. A good stop for a sit-down with your feet in the water between sights.
