A traditional Onsen accommodation with only 11 rooms, quietly nestled away from the hustle and bustle of Atami's Onsen town.
Our inn, nestled in a surprisingly tranquil setting amidst the lively atmosphere of Atami, offers a warm and relaxing retreat. Sanpeiso welcomes you with heartfelt hospitality, where gentle conversations and encounters with nature create moments of happiness during your journey.
I was able to relax and unwind for the first time in a while. The hot water was gentle on my body, and even after soaking for a long time I didn’t feel fatigued.Both dinner and breakfast were thoughtfully prepared and absolutely delicious!Each dish showed great care, and every single one was truly excellent.I sometimes dine at traditional Japanese restaurants to enjoy the atmosphere, but this Accommodation is special—you can stay overnight, soak in the Onsen, and enjoy outstanding meals. I think it’s a rare find.
Tina！！ 9/21/2026Just as the Reviews said, every dish we had been looking forward to was truly delicious. We were impressed by the careful seasoning and attention to detail, even in the side dishes.The Facility felt historic, but everything—including the bath—was well maintained and very clean.We were looking for an Accommodation with a tatami Room so it would be comfortable for our one-year-old. We were a bit nervous that our child might touch the hanging scrolls or shoji screens, but our meals were served separately from other guests, and it was still very easy to spend time here even with a child.Above all, everyone at the Accommodation was warm and welcoming, which made our stay truly comfortable. We’re sorry for any trouble caused by our child, but we sincerely appreciated your kind support until the very end.We visited as a family to celebrate my parents’ 60th birthday, and they were extremely satisfied. It became a once-in-a-lifetime family memory. Thank you very much.

| About Hygiene Measures | ~Notice on COVID-19 Measures at Sanpeiso~
We conduct "identity verification and health checks" for all guests.
The use of shared facilities is limited to a certain number of people to ensure thorough measures against overcrowding.
Shared facilities and guest rooms are regularly disinfected and ventilated.
~Additional Measures~
We use human- and eco-friendly hypochlorous acid (HOCL) water, generated through the electrolysis of water and salt, to clean, disinfect, and manage hygiene in the facility daily.
Reasons for not using alcohol-based sanitizers:
1: Alcohol does not effectively eliminate norovirus or bacteria such as E. coli O-157, Campylobacter, Salmonella, or Vibrio parahaemolyticus that cause food poisoning.
2: Alcohol evaporates quickly, making it unsuitable for wiping surfaces during cleaning.
3: Considering our location in a tourist area, we prioritize environmental sustainability by avoiding sanitizers that negatively impact the planet.
With these hygiene practices in place, we also ensure safe and high-quality ingredients are used in our meals. We look forward to welcoming you warmly.
*We use freshly generated hypochlorous acid (HOCL) water within three days of production from Domisol by Hyunsung Japan Plus Co., a manufacturer with proven results in medical institutions and restaurants worldwide.* |
