Taushubetsu arch bridge...over Lake Nukabira. Water is stored from summer to autumn and it becomes almost full so that the bridge disappears before winter. At this Lake Nukabira which was discharged for power generation in winter, the water level drops while keeping the frozen state. On a full moon night with a temperature of -20℃, I reached this place by walking on a frozen Lake Nukabira for about an hour. I kept waiting for the moon to enter the frame and took this picture with 4 minutes exposure.
