A Property in the Takayama Onsen village, renowned for its milky white hot spring waters and attracting therapeutic visitors since the late Edo period.

Located at an altitude of 1,800 meters within the Joshinetsu National Park, Manza Onsen offers milky white hot spring water flowing directly from its 80°C source. Enjoy the ever-changing beauty of nature through all four seasons and a sky so close it feels like you can touch the stars. Relax in this renowned Onsen with its abundant health benefits while savoring a Japanese-style meal featuring local ingredients.

  • I gifted my 92-year-old mother an Onsen trip for her birthday.The accommodation had a very charming atmosphere, and the Onsen, with its high-concentration sulfur spring, was excellent.My elderly mother enjoyed soaking in the bath four times. The meals were also delicious.This time we stayed for just one night, but next time we hope to have a multiple night stay. The staff were kind and warmly welcomed us. We created wonderful memories. Thank you very much!

  • I visited after skiing in an outside temperature of -10°C. After check-in, I went to the Onsen to warm up my chilled body. The Onsen had a sulfur smell—truly what you’d expect from an Onsen—and it warmed me through. The indoor bath was at just the right temperature and clear, while the open-air bath was milky white; perhaps because the outside temperature was low and it was snowing, it felt a bit lukewarm. When going to sleep, since our Room was a corner Room, the room temperature was on the cooler side and didn’t warm up enough, so they provided us with an extra blanket. The meals were excellent in volume, variety, and taste, and we were very satisfied with both dinner and breakfast. The staff’s service was also good.
