Tennen Onsen Koshu Yokujo (Hamayu), in Nachikatsuura, Wakayama Prefecture, taps sodium-chloride thermal water at 41°C, with an indoor bath, an open-air outdoor bath (rotenburo) and a sauna.
Insider tip — Hamayu Onsen serves the coastal fishing port of Nachikatsuura-cho at the foot of the Nachi Highlands where Japan most celebrated waterfall — Nachi no Taki at 133 metres — plunges in a single unbroken leap into the cedar forest below the vermilion Kumano Nachi Taisha Grand Shrine. The hamayu sea lily that names the spring blooms along the rocky Kumano coastline each summer, and the town harbor is Japan leading port for bluefin tuna with the Katsuura fish market handling live tuna auctions each morning that draw buyers from across the country.
