- stew from Japan writes:
Alpha Resort Tomamu has great tree runs with good pitch and very good quality snow. It's a long track out that is very tiring. Food is excellent at Alpha Resort Tomamu and the wave pool is great. Unfortunately, I believe Alpha Resort Tomamu has the worst layout of any resort on the planet.
