The five add up to the 100-point Powder Score: more fresh snow, more on the way and colder air all push it up. How we measure

A 2022 overhaul gave the lift a new haul rope, communication cable and derailment detectors. From the slope you look straight down on central Obira and the Sea of Japan. Enquiries go to the Obira town board of education, which looks after the hill. Sources: town.obira.hokkaido.jp (sources read 12 Oct 2026; an AI draft the site operator has not yet checked)

The tick marks the median across every Japanese ski area we measure. All four bars run the same way — longer is better.

The quality score leaves out how much snow falls (it uses temperature, frequency, rain and wind).

Compared with what is nearby
