Koshi Kogen is a small ski hill located in the beautiful surroundings of the former Yamakoshi village in the central region of Niigata Prefecture. On a clear day there are some fine views of Mt Sumon and other surrounding mountains to be enjoyed from the top course. Yamakoshi village suddenly became famous in late October 2004 when it bore the worst damage of the Chuetsu Earthquake that hit the region. The village has since recovered and is a beautiful place to visit all year round with lots of traditional Japanese countryside scenery. Yamakoshi is now part of Nagaoka city, the second largest city in Niigata Prefecture.
Niigata Prefecture is located in the central region of Honshu to the north of Tokyo and has a 250km long coastline facing the Sea of Japan. Convenient transportation links make Niigata very easy to get to from Tokyo and other surrounding regions. There are over 50 ski and snowboard resorts in Niigata Prefecture, ranging from small one-lift hills to some of the most well-known and popular ski resorts in Japan. While they are dotted around the mountains of the prefecture, most are concentrated in the southern regions - in particular the Yuzawa town and Minamiuonuma city area in the Chuetsu region and Myoko city in the Joetsu region.

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.

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.
