It has playground equipment, outdoor sports fields, and objects that are designed by Isamu Noguchi, a Japanese American artist.

The name "Moerenuma" (Moere marsh) is derived from the word "Moyre pet" in Ainu language, which means "a slowly flowing river.

The entire area of the park is 1,888,000 m² including the Moere marsh, coming to a total cost of 27 billion yen.

The pyramid has an air conditioning system to cool down inside in summer, using snow stored in a neighbouring storage building during winter.

Hidamari is also used for workshops and events including the Prestigious International Conference on Music and Perception with a concert by John Kaizen Neptune in 2008 in the rooms on the ground and second floors.

The Tetra Mound, an object with triangle stainless steels (one of the creations of Isamu Noguchi) is placed in the western side.

It is 62 metres high,[1] which enables visitors to overlook the landscape of the park and northern part of the Sapporo city.

More playground equipment is near the Forest of Cherry Trees and the Moere Beach, which is a shallow pond open during summer.

Courses are set up, which enable visitors to view objects in the park whilst skiing.

The Sapporo Community Dome, an indoor stadium which is often used as a venue for some sports events, and the Okadama Airport are close to the park.
