The ski area's hut doubles as a free rest house that anyone may use. The family slope is part of the Hachimoriyama Recreation Plaza in the Sanze district of Tsuruoka, and the Sea of Japan is in view from the hill.

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

Which way the slopes face

98% of the vertical on the runs descends to the north or east. Those slopes get the least sun, so the snow lasts longer.

These are analyses of hot spring sources, not a list of baths you can visit. They date from 1910 to 2005, many from decades ago, so today’s temperature and chemistry may differ. Names are as recorded in Japanese. Temperature and pH bands follow Japan’s standard for analysing hot springs.
