It is generally accepted that you kiss decent skiing goodbye anywhere south of Hiroshima Prefecture but there is a relatively excellent board/ski experience just an expressway drive (1.5 hr. from Hiroshima interchange) in Shimane Prefecture- Mizuho Highland Ski Area.
Yeah, yeah I know there are those out there that think Geihoku Kokusai rule but I don't appreciate the seemingly endless drive after getting off the interchange for any other ski areas!
As a past season pass holders of Naeba (Niigata), Nozawa Onsen(Nagano) and Mammoth Mountain, Mizuho may be smaller than other areas close to Hiroshima, but for a one-day commute it's great.
The 4-person gondola and high speed lifts are state-of-the-art and the main lodge, valley side lodge are beautifully designed by the original owner/operator. No bungalow piece-meal planning here. Overall a tasteful presentation.
Lastly, the ice-crushing capability to provide sufficient cover early and late in the season if more than adequate.
If you live close to Hiroshima, Iwakuni, Okayama, even Kita-Kyushu- Mizuho Highland is the way to go!
