What is a dam ?

 Shimagawa Dam

It is not known exactly when dams started to build. Modern dams (mainly concrete) were constructed in England in the early 19th century.

According to Japanese law, a dam is a structure with a bank height of 15 meters or more that can store water from a river.

1. Kurobe Dam (Toyama Prefecture)

The Kurobe Dam is an arch dam located upstream of the Kurobe River in Toyama Prefecture. A total of 10 million people worked and finished its construction. The "Great Project of the Century" took seven years to complete. It is 186 meters high, about the same height as a 50-story building. When you look down from the dam, you feel scary, as if you might be sucked in. The fascinating part is the water discharge, and it is a great attraction. It is held annually from late June to mid-October. More than 10 tons of water per second makes a spray. The sight of the misty water falling is worth a look.

2. Honenike Dam (Kagawa Prefecture)

The Honenike Dam in Kanonji City, Kagawa Prefecture, was the early dam in Japan, built in 1929. It is currently one of the only two examples of a multiple-arch dam in Japan. The Honenike Dam has five arches between its six walls. It is a precious structure that can not be built under the current law in Japan, and its appearance seems to be an old castle in medieval Europe.

The Hakusui Dam is located deep in the mountains of Taketa City, Oita Prefecture. It is approximately 15 meters high and 87 meters wide. Despite its small size, it is called "the most beautiful dam in Japan." Due to the weakness of the surrounding ground, the water is designed to flow in gentle curves. It creates the beauty of water flowing like a curtain. The views from the right and left banks of the dam are different.
