About

K's House Nikko sits in the Kinugawa Onsen (鬼怒川温泉, Kinugawa Onsen) area and has both an indoor bath and a rotenburo (露天風呂, open-air bath) fed by natural hot spring water, with the outdoor bath looking directly over the Kinu River. The baths are gender-separated and the place is openly tattoo-friendly. Day-use bathing is available in the evenings for non-staying guests. The hostel opened in 2022 with a shared lounge, a fully equipped kitchen, and an outdoor terrace.
