The park's highlight is the long roller slide, a giant sphere that lets you plummet down the slope. Based on the concept of Oni-no-Shita-Shita, a scenic spot in Okuizumo, this authentic slide is inspired by the clear streams flowing between rocks and the switchbacks of a trolley train crossing the mountains.

The gently sloping field is packed with outdoor activities that get you moving, including not only slides but also net tunnels, playground equipment, and sand shovel-style play equipment. The height and sense of openness are so impressive that a Sanin newspaper article described it as "a thrill that will make even adults tremble in their legs," providing an exceptional sense of accomplishment.
