A tranquil Accommodation by Shirakoma Pond, surrounded by nature after a walk along the mountain trail

  • Was this my last snowy mountain trip of the season? I enjoyed a relaxed two-day, one-night stay in the snow-covered Northern Yatsugatake. I had been curious about Shirakomaso for a while, and it was clean and comfortable—and above all, everyone was wonderfully kind. I was especially touched that the owner even remembered what I asked about when I contacted them a week earlier.The meals were also very satisfying, with incredibly fresh vegetables. Next time, I’d love to stay during the season when the moss is at its most beautiful. And next time, regardless of hiking plans, I’ll be back with my family.

  • Hearty, vegetable-focused meals. Both dinner and breakfast were very satisfying. Despite being a mountain lodge, there was a warm bath, and the toilets were clean and equipped with washlets—also very satisfying.
