Hilton Niseko located in the base of Niseko Village, where one of the ski slope ended next to their ski shop.
Hot Spring (onsen) opens most of the day, we enjoyed the hot spring a lot (especially the outdoor pool). Breakfast at Yoytei is amazing coming with ranges of selection with mixture of local food and very tasty bread rolls. i enjoyed their miso soup and Hokkaido milk a lot.
Rest of the restaurants are pretty good, we had lunches a dinner from Melt Bar and Grill, their Japanese ramen is surprisingly good with unlimited coffee refill. Buffet dinner also have a lot of selections, totally worth it.
Sushi at Rera is good too, we ordered a very good sake!
