Currently, the mountaintop is bathed in a breathtaking sea of clouds illuminated in golden light. This morning, the clouds in the distance are flowing from east to west, and the clouds in the foreground are flowing from west to east, creating a very rare phenomenon where the clouds form a large vortex above Tomamu. The foothills are shrouded in thick fog, but beyond the clouds, accessible by gondola, an indescribably breathtaking world awaits. This morning, the dynamic movement of the clouds, which change their appearance moment by moment, is a must-see. The outside temperature at the mountaintop is a refreshing 13 degrees Celsius, so please bring a light jacket.
