Tenzan Onsen

183. Tenzan Onsen, Hakone A top-tier onsen in Hakone that needs no introduction. Admission is 1450. Essentially a super sento in a beautifully maintained old ryokan building. The day I visited was very rainy and there weren't many visitors in the evening. The result was a spectacular atmosphere in the bath area: cooling rain, perfectly done evening lighting, great company, beautiful bath aesthetics. Basically, by the time I reached the changing room and saw the baths, I had zero questions about why this onsen is so highly regarded. Baths: 1. Large rectangular wooden bath. Clear water, temperature around 42-43. 2. Corner bath nearby with clear water, just warm temperature. 3. Main large stone bath. Temperature around 40. 4. Additional section next to the large bath, temperature around 44-45. 5. Two mini-baths up the stairs. Temperature around 40. 6. Steam bath in a small house. 7. Cold stone bath. Top-tier. When I'm back in Hakone doing another onsen run, I'll definitely go to Tenzan again.
