Marunuma Kogen is located on the western slopes of Mt Shirane in Katashina village close to the Gunma-Tochigi prefecture border. Marunuma Kogen is particularly popular during the early season and late season due to early snowfall and long season in the region. (During the peak season months there are more easily accessible options). The road just beyond Marunuma Kogen gets blocked off during winter. Marunuma Kogen has been operating since 1974.
The region to the east of Minakami town and to the north east of Numata city in northern Gunma Prefecture is made up of Kawaba village and Katashina village. There are a number of ski and snowboard resorts dotted around the mountains of this region, all of which are accessed off the main Route 120 road from central Numata. This road is otherwise known as the Nihon Romantic Highway and continues through to Nikko in Tochigi Prefecture, though the prefecture border section of the road is closed during the winter months.
Gunma Prefecture is located in the north west area of Kanto region on the main island of Honshu and shares borders with Niigata Prefecture to the north and Nagano Prefecture to the west. There are over 20 ski and snowboard resorts in Gunma Prefecture and they are mainly concentrated in the northern regions of Minakami and Katashina and the western region of the Prefecture.

Marunuma Kogen is located very close to the border with Tochigi Prefecture. Outside of winter months Route 120 continues past Marunuma Kogen and connects with the Oku Nikko area of Tochigi, but that section of the road is closed during winter. This means that the only way to approach Marunuma Kogen in winter is from the west on Route 120.
Marunuma Kogen is just over 38km from the Numata IC exit on the Kanetsu Expressway.
From the Numata IC exit, turn left onto Route 120 (Nihon Romantic Highway) and head towards Nikko. Continue on Route 120 for just over 38km to the base of Marunuma Kogen.
As the 2018-2019 winter season approaches, we are gradually updating the information on these pages (for every ski resort in Japan).
Many ski resorts in Japan do not update their own information until late autumn. Our process of updating information will be ongoing right through until the end of November. In the meantime, ski resorts usually open and close around the same dates each year - so even if the planned season dates shown on this page are still from the 18-18 season, they can be used as a good indication of the upcoming season.
For more details and explanations about the information presented on this page,
please read this.
It is very important to us that the information presented on SnowJapan is correct and up-to-date. Checks and updates are made throughout the year. If you find information that you feel needs checking and updating, please let us know by contacting us. We appreciate your support.
