Hakkoda Mountain
Hakkoda Mountain is the collective name for the multi-volcano mountains rising to the south of Aomori City, with its main peak at 1585 m. It is known as one of the world's heaviest snowfall areas. It is famous for its autumn foliage, which is just now at its best. This year, the first snowfall was already recorded on 6 October.
It can be reached by bus from Aomori City. If you have time, you can visit the famous hot springs or go to Lake Towada to enjoy its mystical beauty, but if you don't have time, the Hakkoda Ropeway is a great way to enjoy a short stay there. Take care, though, as the buses are limited in number!
