The 3-km-wide Kuttara caldera formed 40,000 years ago and contains Lake Kuttara, shown in this September 2019 Planet Labs satellite image monthly mosaic (N is at the top). The complex also contains cones, domes, and craters, and has ongoing geothermal activity. The Noboribetsu geothermal field and the Hiyoriyama Cryptodome are on the W flank, approximately 1.3 km from the lake edge in this view.
