Karuizawa Prince Hotel Ski Resort
Located about a 10-minute walk from Karuizawa Station, this ski resort offers outstanding accessibility. Within its expansive 30-hectare grounds are 16 courses ranging from beginner to advanced, allowing everyone from novices to experts to enjoy skiing.
If you're bringing younger children, I think Karuizawa Prince is a good fit. You don't have to plan on skiing all day. Adults can enjoy the slopes, while kids can play in the snow in the family area, so everyone can have fun in their own way.
