Insider tip — Niikappu Onsen Record no Yu is located in the Hidaka region of southern Hokkaido, an area known for thoroughbred horse farming and volcanic hot springs. The sulfurous waters emerge from geothermal vents fed by the Pacific volcanic arc running along Hokkaido's eastern flank. Niikappu town sits near the coast between Tomakomai and Shizunai, offering a quiet rural onsen experience away from the main tourist routes. The facility name Record no Yu reflects the area's equestrian culture and racing heritage.
