Minenohara Kogen in Suzaka (Nagano Prefecture) has had an eventful few years with change of ownership and then damage caused by a typhoon last autumn.
It was closed last season, but it will re-open for 2020-2021 with an interesting new name:
WILD NINJA SNOW HIGHLAND リワイルド・忍者・スノーハイランド
(It's not clear if the capitals are necessary!)
More info should be coming soon, but the page has already been updated with some details here:
