Manza Onsen is a hot spring resort town located 1800 metres above sea level. Situated high on the slopes of Mount Shirane, in the western region of Gunma prefecture, which is approximately 220 kilometres north west of Tokyo. Gunma prefecture shares boarders with Niigata prefecture to the north and Nagano prefecture to the west.


Boasting great views of Mount Asama, the mountains of Shiga Kogen and even Mount Fuji on a clear day; Manza Onsen ski resort is well known for its powder snow and healing onsens. In fact it is rated in the top 3 in all of Japan.


The snow is dry and powdery with regular snow falls from December until the end of March. Manza Onsen receives an average annual snowfall of over 7 metres, which due to its location and its high elevation means that Manza receives some of the lightest and driest powder snow.


A small resort by most standards due to part of the resort closing many years ago, but there are some great off piste areas within the resort or for those wanting to hike there is untouched powder to as far as they eye can see. There is enough within the resort to cater for all levels of skiers and boarders with family courses to advanced powder courses, there is something for everyone.


Due to the resort's high altitude the hot springs of Manza have been dubbed the "onsen that creates beautiful skin". The milky white water is highly popular particularly during winter; the sulphur springs are renowned for its magical healing powers and the outside baths features panoramic views of the surrounding mountain vista.


Manza Onsen is well suited to the mature traveller looking for fast access from Tokyo, a relaxing onsen experience and with easy ski in ski out access direct from the hotel locker room. Even the most avid and experienced skier or boarder will enjoy their stay here.
