Ryokan in Izu

Nine of the ten reviewed Izu inns sit inland in Shuzenji, Yugashima and Izu-Nagaoka, eight of them on an alkaline simple spring; Inatori Ginsuiso is a big oceanfront inn on the east coast with its own chloride spring. The five Shuzenji inns and Yoshiharu in Izu-Nagaoka run no station shuttle, so plan on a taxi or bus; Ochiairo, Sanyoso and Inatori Ginsuiso run their own. Ogawaya in Izu-Nagaoka gives a free pickup from Izu-Nagaoka Station if you phone at least 30 minutes ahead.

Asaba (luxury) has a working Noh stage across its pond and source-fed baths in every room, but service has been inconsistent. Ochiairo (luxury) is all-inclusive with celebrated saunas, though only three rooms have pure spring-water baths and its main bath is now mixed with swimsuits. Sanyoso (premium) is about the garden and architecture, with long walks and modest meals; Yagyu no Sho (premium) is the pick for in-room kaiseki and quiet, despite worn plumbing and smoking in every room. Arai Ryokan (classic) offers the famous Tenpyo hinoki bath, with steep stairs and cold winter corridors. Yukairo Kikuya (classic), the 400-year-old inn where Natsume Sōseki convalesced, adds four free private baths and near all-inclusive drinks, but its main baths are recirculated, dinner reviews are mixed and much of the old main building has been closed for a refit since early 2026. Inatori Ginsuiso (classic), with 101 rooms above the sea, is the large-scale contrast: warm staff, simmered kinmedai and a free all-day lounge, but book a renovated suite with an open-air bath — older rooms, a dated main bath and corridor smells draw complaints. Shuzenji Onsen Katsuragawa (value), a 116-room shoes-off family inn opened in 2020, is the budget pick: seven free private baths used without booking, buffet meals and free late-night ramen, but its spring water is diluted, heated and recirculated, some guests smell chlorine, and the private baths have queues on busy nights. Izu-Nagaoka Onsen Yumeguri no Yado Yoshiharu (classic), a garden inn running since 1952, is built for bath-hopping: five free private open-air baths you walk into whenever one is unlocked, two large baths, ten rooms with their own outdoor tub and a half-kaiseki with abalone grilled alive over a koi pond, rated 4.7 across 3,442 reviews on Jalan; but its spring water is diluted, heated and recirculated and can feel lukewarm, the slope makes it a maze of stairs, and summer brings mosquitoes. Izu-Nagaoka Onsen Fukuritei Ogawaya (classic), a 12-room inn that has taken guests for more than 100 years, is built for travelling with small dogs and cats: pets stay off the lead in rooms of at least 16 tatami, kaiseki dinner and breakfast are served in the room, staff remember pets by name and a dog foot bath waits at the entrance; it is rated 4.75 across 912 reviews on Rakuten Travel and 4.9 across 548 on Jalan, at roughly ¥18,700–33,000+ per person with two meals. But the large baths are up a long staircase, Jalan lists the water as recirculated and filtered, neighbouring dogs bark, the private baths cost extra except for suite guests and cards are not accepted at the inn.
