Onioshidashi Park

Onioshidashi Park (鬼押出し園, Onioshidashien), located just across the border in Gunma Prefecture, is famous for its dramatic volcanic rock landscape, formed by the eruption of Mount Asama in 1783. The park offers a rare opportunity to explore volcanic rocks in unique and curious shapes, making it a fascinating stop for nature lovers and photography enthusiasts. The rugged terrain and striking rocks create a picturesque and almost otherworldly atmosphere.

In addition to the volcanic rocks, the park offers stunning views of nearby towns and Mount Asama on clear days. At the center of the park is a peaceful temple dedicated to the Buddhist Goddess of Mercy, Kannon, which adds a spiritual touch to the natural surroundings. This park is often visited in combination with Karuizawa, making it a great spot for those exploring the region.
