Jet BathAbout
Yao Oyuba is a day-use bathhouse (sento, 銭湯) in a residential part of Osaka's Yao city, built around a spacious open-air bath and a carbonated soak that regulars keep coming back for. Indoors there's a plain hot bath and a cold plunge, plus a tower-style dry sauna with an infrared stove and a rock stove at the center, with loyly and aufguss service (the women's side has its own salt sauna). The open-air area has loungers and a tatami spot to stretch out, with Mount Ikoma visible on a clear day. The building shows its age rather than looking polished, with a restaurant, a hair salon, and a small farmers' market by the entrance.
