A strong typhoon on 12th-13th October 2019 caused considerable damage at Banshogahara in Ueda City, Nagano Prefecture.
As a result, the ski area did not open for the 2019-2020 winter season.
The good news is that they are back and re-opening for the 2020-2021 season! And it looks like there will be some cheaper lift tickets available to celebrate too.
Updates coming to the page on SnowJapan soon...
