Our road note: Seasonal winter closure (Nov to mid Apr) The live summit weather on this page helps judge conditions today.
When does the Hachimantai Aspite Line usually open and close?
In a typical year it is driveable from March to November. Exact dates shift with the snowpack: a heavy winter can push opening weeks later, and early snow can shut it ahead of schedule.
How high is the Hachimantai Aspite Line?
The summit of the driven road sits at about 1,575 m (5,167 ft), which is why the season is set by snow rather than by the calendar.
