561. Hotel Sekitei, Fuefuki, Yamanashi Visited for higaeri at 1650. Higaeri hours are listed as 15:00 to 19:00. They stamp the Yamanashi 100 Onsen book. Bath photos are from the internet, match the real thing. Indoor bath with clear water, temperature around 41-42. Nice view of the city and mountains through glass when standing. Breathing inside is fine. With a separate entrance from the indoor bath, there's a small outdoor bath with clear water. View of the city and mountains, but all behind fences and railings. 13.05.2025
