Manza Onsen Nisshinkan
Gunma Prefecture／Manza OnsenOpen 24 hours with spectacular views and Gokurakuyu hot springs, a buffet with over 40 dishes, and Japan’s highest sulfur concentration.
An Onsen Property boasting one of the finest baths in the Kanto region, located at an altitude of 1800m, where you can fully enjoy nine natural wooden Onsen. Featuring Japan's highest sulfur concentration, the milky white cloudy hot spring water naturally gushes from the ground. With an overwhelming daily flow of 5.4 million liters, the Onsen is offered in a free-flowing style. From the "Gokurakuyu" bath, where the scenery changes every hour of the day, you may even encounter a sky full of stars. For dinner, enjoy a balanced buffet menu of over 40 dishes, including Japanese, Western, and Chinese cuisine, under the theme "Mago wa Yasashii."
We arrived on Sunday evening. It was obvious we were guests checking in—so why were there so many people???The parking lot was full!! But it made perfect sense. An amazing Onsen!! This is an Onsen Accommodation. No wonder it’s been selected as one of Japan’s 100 recommended Onsen Accommodations.Everything was impressive... just go and experience it!!!!
Yahoo!トラベルユー... 7/8/2026First of all, the baths are excellent. There are three locations with a total of six types of milky white sulfur springs, and the atmosphere was wonderful—absolutely the best.The Room was a Japanese-western style, and it was very well cleaned. The hanger area had a walk-in-closet-like layout at just the right height to open up a suitcase, and I loved how it was designed so that even if you leave it open, it stays out of sight from the Room.Breakfast and dinner are buffet-style. Dinner was average. Breakfast was simple but tasty.The hoto noodles at dinner and the seafood rice bowl at breakfast were delicious.They also had “Ohayo Natto” at breakfast. Personally, for some reason I tend to return to an Accommodation that offers “Ohayo Natto.”There were two disappointing points.First, I ordered additional basashi (horse sashimi) at dinner, but it didn’t impress me.Second: the TV in the Room is extremely small. The placement is perfect for watching while lying on the bed, but it’s too small to see properly. I uploaded photos, so please check them.I felt they could raise the Room rate and make it a premium room by installing a large-screen TV or a projector.This time I chose this Accommodation with an emphasis on baths (sulfur springs), and as far as Onsen go, this was my best experience ever.I will definitely come again, so I hope the TV will be bigger next time.
