brinkmate (inevitable checkmate) (shogi)sub-dam（The Ishigoya Dam (Ishigoya Dam) is located on the Miyagase Dam site, and a visit to the Miyagase Dam is a natural part of the tour.
The Miyagase Dam is often referred to as the Ishigoya Dam, but the dam handbook refers to it as the Miyagase Sub-Dam.
We want to emphasize both the local name and the de facto standard (?). We want to emphasize both the local name and the de facto standard (?) name in the dam handbook, so we have listed them together.
View of the top edge from the left bank
Normally, most sub-dams are less than 15 meters high, so they are rarely introduced in this way, but the Miyagase Dam's sub-dam is a whopping 34.5 meters high!
It is also not just a sub-dam. It is a power plant.reverse osmosis pondIt is a perfect dam that secures the water level for the water supply, reduces the discharge of water from the Miyagase Dam, and even generates electricity. This is no longer an existence that should be dismissed as a sub-dam. It is a dam that works superbly.
Downstream view of the levee from the left bank
It is called a "stone hut," and is quite elaborate in design. It is truly a stone-piled hut. Incidentally, "Ishikoya" is a geographical name, not a name derived from the appearance of the embankment.
View downstream from the top
As I am making this page, I think I should have crossed over to that bridge downstream, and now I regret it....
View of water intake
The water intake on the dam lake side is probably for power generation. Although the term "dam lake" is used, it is not the same as "Miyagase Dam'smomentum reducerWhen I say "yes," I mean it....

| Access to D@M | Get off at Atsugi IC of Tomei Expressway North on Route 129 Soon you will be on Route 246, but keep going north. Turn left at the "Kenritsu Byoin Mae" intersection and continue north on Route 412. As you enter Aikawa Town, a sign for the Miyagase Dam appears. Turn left at the intersection with Main Regional Road No. 514 and follow the road. After passing through five tunnels, there is a road that turns right. If you turn there and see a guard standing there, you are already at Miyagase Dam! In addition, use the incline, etc., to go directly under the Miyagase Dam. It takes about 10 minutes to reach it on foot from directly below. | |
