河内5号源泉、金谷温泉 以上2源泉による混合泉

Kawachi No.5 Spring + Kanaya Onsen (blend of 2 sources)

Operated by · 金谷旅館

Mixed source

湯
Simple
Known good for
  • Smooth skindry, rough skin
  • Recoveryfatigue, stress

A simple thermal spring blended from two sources (Kawachi No.5 and Kanaya Onsen). Hypotonic and weakly alkaline, it has a soft, gentle feel on the skin and sits in the Japanese beauty-water family. The wellhead runs lukewarm at 36.2 °C, so it is reheated for bathing; with no dilution, recirculation, or disinfection, it stays an undemanding, lightly mineralized soak.

About

The senninburo at Kanaya Ryokan is, by common account, the largest all-hinoki (cypress) bath in Japan. Built in 1915 (Taisho 4), the vast wooden hall stretches roughly 20 metres and bathes you in the clean, warm scent of cypress throughout. It is a mixed bath (konyoku): women can also enter a connected women's bath and benefit from women-only hours. The ryokan itself was established in 1867 in Izu, Shizuoka, tucked in a quiet valley with spring water flowing directly from the base of Kanaya Mountain. Beyond the great hall, there is also a small outdoor rotenburo for those who want open sky. The combination of hot spring water, cypress, and a 160-year-old inn is genuinely hard to find elsewhere.

Kanaya Ryokan Senninburo A must-visit place on the Izu Peninsula. A huge, deep konyoku bath. There is a separate section with cool water, which is very pleasant to alternate with the warmer water. Rotenburo with utaseyu included. In the indoor bath, the ceilings are high, statues rise out of the water, there is wood everywhere, and lots of windows, a truly unique atmosphere. One of the popular mixed baths, where there are really many visitors of both sexes. Towels are allowed, and there is a separate entrance and a separate bath for women. This time we stayed overnight, there are large rooms for 6 people on the second floor right above the bath. Very authentically Japanese, but I suspect they are cold in winter. There are windows almost all around the perimeter.

Kanaya Ryokan 1000 Person Bath A very atmospheric historic ryokan, founded in 1867, with the bathhouse rebuilt in 1915, and its famous wooden mixed bath for “1,000 people” (senin-buro), built in the sukiya style from Japanese cypress, hinoki. A huge 24-hour indoor konyoku bath, with towels for women available on request. The bath has varying depth, about 50-120 cm in different sections, and is hot. Through a partition there is also a warm bath at about 36-38°. There is also a free kashikiri for half an hour in a separate pavilion, and at reception you can take a sign that says occupied/free. The bath photos were taken from the internet, and they match reality. The rooms traditionally do not have their own shower, it is in the onsen. The ryokan temporarily does not have its own kitchen, so we took a room without breakfast or dinner. A 7-Eleven ten minutes away on foot and a microwave on the 1st floor saved us, and there are almost no places in the town to grab a bite in the evening. Despite the small flaws, it is a very warm and welcoming place, and the staff really try hard. 05.07.2026

211. Thousand-Person Bath Kanaya Ryokan, Shimoda ★★★ A legendary ryokan for a thousand people, famous for its mixed indoor large bath. Day-use is listed from 9:00 to 21:00, and it costs ¥1,200. They stamp 60 Shizuoka onsen. The bath photos and videos from the internet match. The indoor large bath is mixed bathing, with several levels inside. The water is clear, and the temperature is hot. It looks like the bath from old museum photos, where a whole crowd of people sits in one bath. Breathing inside is fine. There were quite a lot of people, but the only inconvenience was in the changing room. From the indoor bath, there is a passage to a small outdoor bath with one utaseyu. The water is clear, and the temperature is hot. If mixed bathing does not bother you, then this is definitely a must-visit. The view and atmosphere in the indoor bath are very cool. 20.07.2024
