During these months, the Tateshina area is covered in snow, and ski resorts like Tateshina Tokyu Ski Resort and Pilatus Tateshina Snow Resort are fully operational. The crisp mountain air and snowy landscapes create a serene environment for winter sports enthusiasts.If you prefer hiking, exploring nature, and enjoying the cooler mountain air without snow, then late spring (May to early June) and autumn (late September to October) are excellent choices.
