Around Shimoda Open Port Museum × Zen-Inspired AccommodationRecommended Hotel·Ryokan

A traditional Japanese Ryokan with a sukiya-style design, surrounded by clear streams and lush forests, featuring a beautiful garden. Immerse yourself in the ultimate relaxation unique to Seiryuso, nestled within approximately 2,000 tsubo of verdant nature and gardens. Enjoy the natural flowing Onsen, the newly renovated Onsen pool, the luxurious Kelo sauna made from Finland's finest "wooden jewel" material called Kelo, and the Roman-style aroma sauna zone "Thermarium," where you can relax in swimwear for an indulgent experience.

Established in 1867 (Keio 3). A tranquil property nestled at the foot of Mount Kanaya. Featuring Japan's largest cypress bath, "Senninburo," and "Manyo no Yu," the largest wooden women's bath in the country. All our baths are fed by natural onsen sources 24 hours a day. Enjoy the rustic beauty of Japanese architecture harmonizing with nature while indulging in the diverse onsen experiences we proudly offer.

Enjoy exclusive use of a 170-year-old historic residence, certified as Shimoda Town Heritage No. 1, for one group only. The dignified building features traditional namako walls and preserves master craftsmanship that is difficult to recreate today—round windows, kumiko latticework, transoms, and gently wavering antique glass throughout. In the early Showa period, an annex was added to welcome leading figures from politics and business, and it still retains the atmosphere of a refined guest space. Soak in the free-flowing Onsen fed directly from the source and spend unhurried time gazing out at the garden. Rather than simply staying at an Accommodation, you can experience what it feels like to inherit a historic residence all to yourselves. Discover Shimoda’s history and architectural beauty—something you won’t find at a Hotel or Ryokan.
