Vertical rise or drop are both common snow terms used to give a good indication of the size of a mountain resort

Happo One has a respectable 1071 meters of vertical drop (also known as vertical rise or just “vert”) meaning if you measured a line straight up from the altitude of the lowest chair lift upload point which is at 760 meters above sea level (ASL) to the highest lifted offload point on the mountain at 1831 meters ASL the total measurement equals 1071 meters. It is an impressive mountain resort and deserves it’s reputation as the best in Japan. To compare that to other resorts around the globe – 

Vail, Colarado, USA – 1025 meters

Big White, BC, Canada – 810 meters

Zermatt, Switzerland – 700 meters

Perisher, Australia – 430 meters
