Things to Do in Zao

Okama is a stunning emerald-green caldera lake nestled in the Zao mountain range, formed within a volcanic crater at 1,771 meters altitude. Often called the 'Five Color Pond' due to its changing water colors, this natural wonder offers breathtaking views and refreshingly cool mountain air even in midsummer. Visitors can access the crater rim via ropeway from Zao village, by bus from Yamagata, or by driving to the upper parking lot, with scenic hiking trails available around the area.

The Zao Echo Line is a spectacular 17-mile winding mountain road that climbs to 1,500 meters elevation, offering breathtaking views as it snakes through dramatic hairpin turns toward the sacred Okama Crater Lake. This scenic drive transforms with the seasons—from stunning autumn foliage that paints the mountainsides in vibrant colors, to the famous spring Snow Wall Walk where towering corridors of snow create an otherworldly experience. Whether you're chasing fall colors, marveling at spring snow walls, or enjoying summer's lush greenery, this route delivers an unforgettable journey through one of Japan's most dramatic mountain landscapes.

Sankai Falls is a magnificent 140-meter cascading waterfall system flowing through the lush forests of Zao, featuring multiple tiers that create a stunning natural spectacle. The falls are best viewed from the observation deck along the Echo Line, where visitors can appreciate the impressive scale of this multi-tiered wonder, especially breathtaking during autumn foliage season. While accessible by hiking trails from Zao Nature House, the remote location and narrow access roads make this a rewarding destination for nature enthusiasts seeking an off-the-beaten-path experience.
