Yoshikawa Onsen Yokatan is set in Miki, Hyogo Prefecture. The sodium-chloride thermal water surfaces at 40°C, serving an indoor bath, an outdoor bath (rotenburo) and a sauna.
Insider tip — Miki city is Japan's premier hand tool manufacturing center — particularly famous for Miki saws (nokogiri), chisels, and hand planes crafted by artisan smiths who have worked in these hills for over 400 years. The Miki Tool Museum and Miki Spring Festival celebrate this heritage. 'Yokatan' is a warm Kansai dialect expression meaning roughly 'wasn't that good!' — a bath name that promises heartfelt satisfaction in the language of the region. After touring the smiths' workshops and selecting a handmade tool, soaking in Yoshikawa Onsen is the quintessential Miki artisan day.
