Sayama ski resort – indoor ski resort Japan
Yes there are several indoor ski resorts in Japan. They use artificial snow. There are three near Tokyo: Snova Shin Yokohama, Snova Mizonokuchi and Sayama Ski Resort.
It depends on a few things – period length, equipment rental etc – but generally it costs around 4000 yen to ski or snowboard at an indoor ski resort in Japan.
Sayama Indoor Ski Resort
Just 40 minutes from Tokyo you can enjoy indoor skiing and snowboarding at the Sayama Ski Resort in Saitama.
In 2019 they closed for renovations. But it looks like they plan to reopen Autumn 2020:
The Sayama Ski Resort, a Prince Snow Resort and part of the Seibu Group, opens annually toward the end of October. Usually they open the resort from the last weekend of October on weekends only and then open full time from mid November. You can see the up-to-date information for this year (and any subsequent years) in the event post, which is updated annually in the events calendar.
It is an artificial snow resort, best suited to beginners and intermediate level skiers and snowboarders. They don’t have any special play attractions for children. They do have ski lessons for children on Saturdays. There is good information in English on this site: https://www.snowjapan.com/japan-ski-resorts/saitama/tokorozawa/sayama
