Gassan is a small ski hill located on the southern slopes of Mt Ubagatake (to the south west of the Mt Gassan peak) in the central region of Yamagata Prefecture. Large amounts of snow fall on the mountain and the ski hill only opens for the late spring season - usually from April until late July. There is only one pair lift and some t-bars, but unlike most ski hills in Japan there are not many trees - the skiable area is a relatively wide open area and backcountry tours are popular. When other ski resorts are closed in late season, Gassan can be very busy especially on weekends and holidays.
Yamagata Prefecture is located in the south-west part of Tohoku with the west coast facing the Sea of Japan. The boundaries of Yamagata Prefecture are all mountainous with Niigata Prefecture and Fukushima Prefecture to the south, Akita Prefecture to the north and Miyagi Prefecture to the east. The ski and snowboard ski hills in Yamagata range from very small one-lift local hills to the biggest individual ski resort in Japan (Zao Onsen) and are spread across the Prefecture.

The 2018-2019 winter season is approaching! Hurray!
At the time of writing more than 60% of the ski hills in Japan have still not updated their own information for the upcoming season. We are continuing to manually update the information on these ski resort pages of SnowJapan but for the moment things are unavoidably a mix of old and new. In most cases ski resorts open and close around the same dates each season, so even if the planned season dates shown on this page are still from the 2017-2018 season, that is usually a good indication of what to expect this time round.

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.
