Okama Crater

Located between Yamagata and Miyagi Prefecture, Mount Zao is the tallest mountain in the area with a height of 1841m. Popular all year long where people go either to ski in the winter or go trekking in summer, Mount Zao is also famous for its stunning Okama crater filled with sulfurous green water. While it is forbidden to get close to the crater itself, the view from Mount Zao and its natural formation is breathtaking and by far our favorite in the region.
