A circular crater lake in the Zao mountain range is called ”Okama” due to its shape resembles a bowl. About 2,000 years ago, the water collected at the crater created by the eruption became a beautiful lake. Depending on the angle of the sunlight, the beautiful emerald green surface of the lake turns to many different colors within a day. Locals also call it ”the lake of five colors”.
There are three convenient viewpoints around Okama. The first one is called "Okama Tenbodai" (Okama Observatory) - easy access, right in front of the parking lot. The second one is Mt. Katta and it's just 10 min. walk from Okama Observatory. The third one is a mountain trail called "Kuma no Se" (Horseback) or "Kuma no Dake" (Mt. Kumano). It is not an easy walk, so be sure to prepare your tracking shoes and climbing clothing.
