Takenoyu Onsen, located in Miki, Hyogo Prefecture, taps sodium-chloride water at 41°C. The facility includes an indoor bath, an outdoor rotenburo, and a sauna.
Insider tip — Takenoyu, the bamboo bath, serves Miki City, Japan undisputed capital of hand carpentry tools where master blacksmiths have produced high-precision planes (kanna), chisels, and saws prized by the world finest woodworkers for over 300 years. Miki tools were already famous enough in the 16th century for Toyotomi Hideyoshi to place specific orders for construction of Osaka Castle, and the craft lineage continues unbroken in the hillside workshops.
