539. Kofu Kinenbi Hotel, Kofu, Yamanashi ★ Visited for higaeri at 1500 (includes a towel set). Higaeri hours are listed as 13:00 to 22:00 (Thu-Tue) and 16:00 to 22:00 (Wed). They stamp the Yamanashi 100 Onsen book. 1. Indoor area. Breathing inside is fine. 1.1. Large bath with clear water, temperature around 41.5. 1.2. Small bath with clear water, temperature around 42. 2. Outdoor wooden bath, no view (behind a fence). Clear water, temperature around 42. Bath photo is from the internet, matches the real thing. Pleasant onsens, though the price is a bit steep for this kind of higaeri. 11.05.2025
