Natural Hot Spring Saku-no-Yu Saku Ichimanri Onsen Hotel (BBH Hotel Group)

Nagano Prefecture/Saku City

Rejuvenate with 8 types of baths, 2 types of saunas, extensive amenities, and a breakfast featuring local ingredients.

The Hotel boasts natural Onsen with eight types of baths and two types of saunas for men and women respectively. Room types are abundant, including single, twin, double, Japanese-style, and Japanese-Western-style rooms, accommodating groups and parties. Located just 10 minutes by car from Saku-Daira Station on the Hokuriku Shinkansen or the Saku IC on the Joshinetsu Expressway, and only 30 minutes by car to the popular Karuizawa, our hotel offers excellent accessibility as a base for business and sightseeing.

  • Despite the holiday season, I was able to stay at this accommodation at a reasonable price. The roads were not crowded, and for dinner, you can borrow an electric bicycle for free. There are also nearby options like Kappa Sushi and a large supermarket, so there’s no inconvenience. The breakfast was very satisfying, with everything tasting delicious. The onsen is small but offers variety and has a spacious sauna. The water quality felt similar to that of Tokyo's day-use onsens. It was unfortunate that the walking bath seemed to have been discontinued. You can choose from different shampoos, and services like late-night ramen were excellent as well. On the second floor, you can relax using free massage chairs among other amenities. I would definitely love to stay here again!

  • Stayed 4 or 5 times? I love this Onsen and often stay here during business trips or vacations! This time, I stayed for two nights to relax! Will the walking Onsen ever return? On the first night, I ate too much breakfast as always (haha). I look forward to staying again!
