Onioshidashi Park

Onioshidashi Park (鬼押出し園) in Gunma Prefecture showcases a surreal volcanic landscape shaped by the dramatic 1783 eruption of Mount Asama. Jagged lava formations stretch across the park, creating bizarre and striking natural sculptures. Walking trails weave through these dark rock fields, allowing visitors to explore the rugged terrain up close while taking in panoramic views of Mount Asama and the surrounding valleys. The contrast between the rough lava and the distant greenery makes it especially captivating for photographers and geology lovers.

Amid this dramatic setting lies Asamayama Kannondō, a tranquil temple dedicated to Kannon, the Buddhist Goddess of Mercy. The temple adds a spiritual touch to the otherwise raw and powerful landscape. The park is easy to navigate, with well-kept paths and clear signage, and also features a small museum, rest areas, and souvenir shops. Many travelers visit Onioshidashi Park as a scenic detour from nearby Karuizawa, making it a convenient and rewarding addition to any itinerary in the region.
