About Miyagase Dam
Miyagase Dam is located on the Nakatsu River, a tributary of the Sagami River, which flows through central Kanagawa Prefecture.
The dam, one of the largest in the metropolitan area, is 156 meters high and 400 meters long, with an embankment volume of approximately 2 million cubic meters and a total storage capacity of approximately 200 million cubic meters.
Cable car
The Miyagase Dam is served by a cable car (for a fee) that utilizes part of the dump truck-mounted incline used during construction, and can be used up and down the dam.
In addition to the cable car, visitors can also take a free elevator (currently inactive) that passes through the dam, or a 20-minute walk through Kanagawa Prefectural Aikawa Park witch is next to the dam.
View from Miyagase Dam
From the top of the dam, you can see as far as the Minato Mirai area.
There is also a “Water and Energy Museum” with a restaurant nearby, where visitors can learn about the Miyagase Dam.
