Relaxing Suwa Onsen Inn Sui-Suwako

Nagano Prefecture/Kamisuwa Onsen

A hidden Ryokan with only 8 rooms, each featuring a private open-air bath and offering a stunning view of Lake Suwa.

Escape the bustle of everyday life and gather with those who matter most, as peaceful moments of relaxation gently unfold. Here in Suwa, Shinshu—the heart of Japan—your journey back to yourself begins in a special place embraced by the mystical Lake Suwa and Suwa Taisha Shrine.

  • Both dinner and breakfast were served in a private dining Room, so we could relax and eat at our own pace. The service timing was perfect, and we were fully satisfied with the quality and generous portions of the meals. We also loved that they featured plenty of locally sourced ingredients.The fireworks were spectacular from the rooftop, and the open-air bath in our Room was excellent.

  • Three of us stayed as a family: an elderly couple and our adult son. We happened to find that everyone had time off, and this was the last available Room we could book one week in advance. It was a standard type and felt a bit small for three people, but it was practical and easy to use. The in-room bath facilities were excellent, so we could relax and enjoy the Onsen many times. Even from the in-room bath, you can view Lake Suwa through the window. Since it’s on the second floor, you can block views from people walking along the lakeside by closing the lower shoji-style screen by the window. The rooftop panoramic bath offered great views of all of Lake Suwa and even fireworks rising from the lake surface. Using both the in-room bath and the rooftop panoramic bath depending on your mood makes the stay even more satisfying. The meals were great, of course, but what stood out most was “8 types of local Suwa brewery Junmai Ginjo” at the sake bar held on the first floor at night—it was outstanding. We truly enjoyed a calm, grown-up trip.

About Hygiene Measures
【Introduced on June 1, 2020: Original Hygiene and Disinfection Program】 At Sui Suwa Lake, we have implemented our original hygiene and disinfection program starting June 1, 2020. Our accommodation has always prioritized the safety and peace of mind of our guests by maintaining strict hygiene management, including measures to prevent the spread of COVID-19. To ensure an even safer stay for our guests, we have developed and implemented a comprehensive hygiene and disinfection program. 【Original Hygiene and Disinfection Program】 The newly introduced program as of June 1, 2020, consists of three main perspectives: 【1】"Facility Hygiene Management" 【2】"Prevention of Infection from People" 【3】"Hygiene Management Training." In addition to the previous efforts in hygiene management, new action standards have been established to avoid the "Three Cs" (Closed spaces, Crowded places, Close-contact settings) while adhering to principles such as "Do not bring bacteria or viruses," "Do not let them multiply," and "Eliminate them." These measures are designed to create a safe environment for both guests and staff. This program is based on guidelines from the Japan Ryokan & Hotel Association's “COVID-19 Response Guidelines for Accommodations (Version 1)” as well as the Ministry of Health’s “HACCP-based Sanitation Management Handbook.” ### 【1】Facility Hygiene Management - Installation of alcohol sanitizers in all guest rooms and public spaces. - Ozone sterilization during late-night hours or after check-out (public spaces/kitchen). - Use of humidifiers with disinfectant solution in public areas during nighttime. - Disinfecting with sprayers after room cleaning/public space cleaning. - Alcohol disinfection at high-touch points. - Five-step room disinfection process: (1) Cleaning (2) Alcohol sanitization (3) High-temperature washing/disinfecting glassware before placement (4) Sprayer-based disinfection (5) Sealing with a sanitized sticker. - Thorough cleaning in large baths/private dining rooms/public areas. - Frequent ventilation throughout all facilities. - External sanitation audits conducted regularly. - All rooms are non-smoking; designated smoking areas provided per regulations. - Shuttle service vehicles disinfected with alcohol; humidifiers installed inside vehicles. - Strict food safety protocols following HACCP standards applied in kitchens. - Sanitizing delivered ingredients/supplies upon arrival. - UV sterilization for remote controls/devices used by guests. ### 【2】Prevention Measures Against Human-to-Human Transmission – Daily temperature checks/health monitoring logs maintained among employees daily pre-shift routines include gargling handwashing mandatory mask-wearing gloves worn meal-prep serving-related tasks optional face shields available private course-meal-style dining options offered reduced capacity limits enforced across premises pulse oximeters loaned isolation cooperation requested symptomatic individuals guidance sought local health authorities shuttle-riders sanitize hands wear masks maintain social distance suppliers comply PPE requirements elevator/bathroom conversations discouraged
