Скачать или смотреть Exploring Okama Crater!

My friends and I explored a natural wonder called the "Okama Crater"! Check it out.

Here is a description from Gaijin Pot

This enormous crater lake with a circumference of 1,080 meters is situated in between Mount Katta, Mount Goshiki and Mount Kumano within the Zao Mountain range. Bordering both Miyagi and Yamagata prefectures, the lake’s unique color makes it one of the most photogenic areas in the Tohoku region.

The crater was formed by a volcanic eruption in the 1720s and the volcanoes in Zao are still active to this day. Considered a “symbol” of Zao, the 27-meter-deep lake cannot sustain life because of the water’s acidity.
