This 20-hectare park was established in March 1989 on the former site of Camp Drake, which was confiscated by the U.S. military in 1945, to ensure a comfortable living environment with beautiful urban landscape. The park is well known as a place for sports and recreation, with an outdoor plaza and jogging course. This vast park is also used as an evacuation site. Nearby are Tokyo Metropolitan Oizumi Central Park, Oizumi Sakura Sports Park, Tokyo Yono Green Belt (Nagakubo Ryokuchi), Niiza Green Path and Sakae Green Path in Niiza City, together serving as a large green belt that straddles municipal and prefectural borders.

Myoonzawa springs up from a steep wooded slope located along the Kurome river in the southern part of Niiza, Saitama. It is a clear stream selected by the Ministry of Environment as one of the "Top 100 Waters of the Heisei Era." Myoonzawa covers a stretch of about 100 m before joining with the Kurome river. You can find many rare creatures and plants that only can live in the cleanest of waters in this exceptional stream.

Mizuko Kaizuka Park covers roughly 40,000 square meters and was built to protect and utilize a historically designated site of midden (ancient waste collection spots) significant to the first half of the Jomon period (approximately 5500 to 6500 years ago). The size of the site represents the original ancient village, a path spanning 582 meters encircles the park, and 5 pit-houses (shelter houses built into the ground) and the Jomon era forest which surrounded the village have been restored. At the exhibition hall, excavated dwelling sites have been replicated, demonstrating how the ancient people lived at that time utilizing the midden. There is also an adjoining archive museum displaying artifacts unearthed from the city's ruins, with stone tools from the Paleolithic era roughly 30,000 years ago, designated cultural property Jomon pottery (nicknamed “flying squirrel-shaped pottery” ) unearthed from the ruins of Hazawa, an iron sword and a glass bead from the beginning of the Kofun period, and numerous other artifacts representing the primitive and ancient times of Fujimi City.

The Nobidome Yosui irrigation canal was diverted from the Tamagawa Aqueduct (Tokyo, Kodaira City) in 1655 to use as drinking water by the pioneers of the plateau, by order of Kawagoe’s daimyō, Matsudaira Nobutsuna, to his vassal, Yasumatsu Kinemon. Today, a promenade set up around the canal transforms this road into a valued spot for nature and relaxation. It has a total length of about 24 km, and also nourishes the rice paddies of Shiki City, Muneoka.
