Arimine and Jinzu River dams in Yatsuo Town, Toyama City.Yao Dream Forest YuyuukanWe decided to stay overnight at the Toyama City Family Park, play at the Toyama City Family Park the next morning, and stop by a dam on our way back home. Yatsuo Dam was the first dam we visited that day.
to OsakaYao CityThere is a city called "Yatsuo", which is read as "Yatsuo". This Toyama CityYao Townis also famous for the "Owara Kaze no Bon Festival," a folk song event representing Toyama Prefecture that takes place every year from September 1 to 3.

The weather was holding at the family park, but it started raining around the time we reached the dam. However, we found that we could only take pictures from this spot.

Instead of changing the angle, they just changed the height and width 😓.
It is mid-summer. The jungle-like weeds that have fully grown make it even more difficult to photograph. Incidentally, from this position, the right bank on the other side of the river is blocked by a gate.
The Yatsuo Dam is owned by the Toyama Prefectural Bureau of Public Enterprises and is dedicated to power generation. Water taken from the Yatsuo Dam produces up to 7,600 kW of electricity at the Yatsuo Power Station, located approximately 2.5 km downstream in a straight line. The Yatsuo Power Station appears to have been constructed as a reverse control power station.
The Yatsuo Dam is built on the Ida River, but on Google Maps it is labeled as the Muromaki River, not the Ida River. I wondered why, so I looked it up. In Gifu Prefecture, it is called the Harayama Main Valley, and when it enters Toyama Prefecture, it is called the Yatsuo Town, Toyama City.Ohnagatani (great-grandchildren)In the Oyasegawa district, the river seems to change its name to the Oyasegawa River, and in the Muromaki and Niho districts, it changes its name to the Muromaki River, which merges with the Nozumi River at Takakuma, Yatsuo Town, Toyama City, and becomes the Ida River.
It is common for large rivers that straddle prefectures, such as the Shinano and Chikugo Rivers, to change their names, but it seems unusual for names to change from district to district within the same city.
...and it was the Yao dam, which has more words than images.
