Seiryu-so
8,9/10 Excellent - Based on 198 reviews
Seiryu-so is a garden-front ryokan set in a wooded valley of Shimoda on the Izu Peninsula, presenting a measured blend of traditional rooms and contemporary wellness facilities. Rooms range from tatami-style suites to those with their own outdoor baths, and the property provides a short walk from the local station or a complimentary shuttle from Rendaiji or Shimoda stations on request. The setting and room types make it straightforward to plan a stay focused on relaxation and thermal bathing, positioning the property as a ryokan with private onsen on the Izu Peninsula without overstating its scale.
The spring system is central to the experience: three on-site sources feed a continuous flow of about 506 litres per minute into colourless, soft alkaline water (pH ~8.2) with outlet temperatures around 56.7°C, 43.3°C and 30°C. Guests can use rotating gender-segregated indoor and open-air baths—one large indoor black-stone tub is renewed hourly—and may book a small private open-air bath for reserved 50‑minute sessions; several room types also include private open-air baths. The mineral water is presented for gentle bathing and is described as supportive for neuralgia, muscle ache and sensitivity to cold, fitting the profile of a ryokan with private onsen in Shizuoka.
Beyond bathing, the property operates a year-round natural hot-spring pool kept near comfortable temperatures, multiple sauna formats including a wood‑fired Finnish sauna, a thermarium and an on-site spa offering aromatherapy and hands-on treatments. Dining highlights local Izu seafood and seasonal produce served as multi-course meals, while garden paths and terrace spaces invite quiet time after the baths. Facilities such as poolside relaxation areas and spa treatments are bookable in advance to coordinate with bathing times and room-use of private baths.

Negative Reviews
Dining limited and must be pre-booked
Several guests reported no on-site restaurant for casual dining and that dinner/breakfast experiences must often be reserved in advance or are at capacity, reducing flexibility and forcing guests to eat off-site.
Remote location and transport constraints
The property is somewhat far from Shimoda center; public transport is limited (infrequent buses, shuttle schedules) so guests may need taxis, cars or to plan around shuttle times, especially in the evening.
Limited evening options nearby
Reviewers warned that nearby businesses close early (around 7pm) and there are few dinner options within walking distance, which can make evening meals difficult if you don’t book the ryokan’s dinner.
Occasional cleanliness / maintenance concerns
A small number of reviews mentioned issues such as mold, aging or poorly maintained rooms and garden equipment, indicating inconsistent upkeep in some areas.
Language / service limitations and inconsistent extras
Some guests experienced difficulty communicating in English with staff or found certain services (e.g., massage quality, laundry availability) disappointing or limited, and additional services may be costly or require advance booking.
