The park surrounds the Miyagase Dam, a massive concrete structure that performs both flood control and water supply functions.
The 330-meter-long Miyagase Rainbow Bridge is the longest pedestrian suspension bridge in the area.
The lake was created by the impoundment of the Nakatsu River, which necessitated the relocation of the original Miyagase village.
The park hosts a major Christmas illumination event annually that utilizes a giant, naturally grown Japanese cedar tree as a centerpiece.
The reservoir serves as a critical water source for several cities in Kanagawa Prefecture, including Yokohama and Kawasaki.
Water release events from the dam occur periodically, creating a man-made waterfall effect.
Miyagase Lakeside Park is a large-scale waterfront facility centered around the Miyagase Dam and its reservoir, Lake Miyagase.
