There weren't any beer vending machines at the Lodge when I was there. But if you ask the front desk, they may or may not know how you can procure some biru.
For dinner, Raphael is the only restaurant around Moiwa. The other option is to hike it to Moku No Sho onsen hotel (about 10-15mins) and see what they have in their kombini / souvenir shop. Usually yakisoba buns and bento boxes. This is a chicken katsu and tempura bento with Niseko Sake.
Such a cool little hotel. Just across the road from Moiwa ski resort.
The margherita pizza from Restaurant Raphael which is in the same building as Lodge Moiwa.
Nice modern capsule. Enough space to sit up and get changed. A roller privacy shutter to keep the noise down. There is a lockable compartment under each capsule with enough space to store your luggage and board bags.
