Vibrant Caldera
Mount Haruna, one of Gunma's Three Mountains of Jomo, features the stunning Lake Haruna and the iconic Mount Haruna Fuji within its caldera. In autumn, the mountain is blanketed with vibrant foliage, best enjoyed from the summit, accessible by hiking or ropeway. Visitors can also explore Haruna Shrine, enjoy views of nearby peaks and plains, and relax at hot springs near the lake.
