  • Exceptionally silky, wonderfully comfortable hot water

    This Accommodation has outstanding Onsen.I visited this time because I wanted to relax quietly and simply soak in the Onsen.The hinoki indoor bath in the Room also had an amazing fragrance. It isn’t an Onsen, but I ended up using it several times—it was such a soothing bath thanks to the hinoki scent.And above all, the large public bath Onsen.The three Hotels next door—“Senkyukaku,” “Hanamaki,” and “Koyokan”—offer a fun hot-spring hopping experience across all three. However, I was told that “Kashoen” uses a different source spring from those three Hotels. It truly was different—the water is wonderfully silky. Really. It was such pleasant water that you won’t regret trying even once.There’s no need to bring towels from your Room, so there’s no bath basket provided—but everything is available at the baths: towels, amenities, and more.There are also free massage chairs in the post-bath lounge area, and even towels prepared for placing on the chair seats—this Accommodation offers attentive service down to the smallest details.The Room is comfortable as well, and at night torches are lit in the garden, creating a lovely atmosphere.I would definitely like to stay again.

  • I stayed here because I was drawn to the Onsen.

    Many Reviews praised the quality of the hot spring, so we decided to stay here as a stopover on our way to Hakodate. The Shuttle Service was provided, and we were able to relax and enjoy our meals served in our Room. The amenities and loungewear were also more than satisfactory, making for a wonderful sisters’ trip. If I had to mention one thing, the smell in the Room bothered me a little. Other than that, we were very satisfied. Thank you for taking care of us.
