Okama
The caldera lake held in the three ridges of Mt. Katta, Mt. Kumano, and Mt. Goshiki in the Zao mountain range got its name because of its shape like a kettle (kama, in Japanese).
The circumference of the lake is about 1,080 meters with a diameter of about 325 meters. The emerald green surface of the lake is also called a five-color marsh (goshiki-numa, in Japanese) because it changes color depending on the weather and how the sunlight hits the water.
