Resort name is also written as Shiga Kogen Sun Valley.
Also stayed at Villa Alpen at Sun Valley (Shiga Kogen Sun Valley) in 2010 and going back in 2011. I can add a few things:- Distance to ticket office :- 20m Distance to lift 30m Excellent food at Villa Alpen. Captain and his family will ensure you have a great stay. Onsen in lodge great for relaxing in. You can either ski your way over to the other resorts or, if you're in a rush, you can take the free bus up to the other ski-areas.
