Okama

🌿 Nature & Parks · Zao, Miyagi · ★4.6 (2,692)

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.

💡 Tips for Visitors

Bus service from Yamagata is infrequent, so check schedules carefully and plan for approximately 2 hours travel time. The weather at this altitude can be unpredictable with sudden fog and strong winds, so bring warm layers and waterproof clothing even in summer. If driving yourself, note that the access road (Zao Echo Line) is typically closed from November to late April due to snow.
