This large park is on the outskirts of Sapporo,Japan. It was designed by renowned Japanese landscape architect and artist Isamu Noguchi.
It features an art gallery inside a giant glass pyramid, a human-made geyser, or perfectly sculpted hills (perfect for sledding down in Sapporo's long winters!),and sculptures hiding between the 3000 cherry trees.
You can also hire a pair of cross-country skis or snowboots in winter, or a bike in summer!
