Location: Shimoyama Oninodaira, Toyota City, Aichi Prefecture
The movie file of the discharge on 8/16/2003 isthis way (direction close to the speaker or towards the speaker)I'm in the middle of it! (543KB)
I'm sorry to those who said, "I'm not interested in watching a video" or "I don't want to watch a video! I am very sorry for those who say "I don't want to see a video" and for those who are in the narrow band, so I will also publish still pictures. The upper photo was taken from the right bank on the downstream side, and the lower photo was taken from the embankment. Every time I go to Habu Dam, there is a drought, and I have never seen such a discharge before. Moreover, water was discharged from all the gates. (Added on 9/3/2003)

A series of dams that are close by but not often covered? Habu Dam is one such dam in this series. To approach the dam, from the Nagoya area, take Route 153 through Toyota City to Route 301. If you continue on through to Shimoyama Village, you will be able to reach the dam quickly as there are signs everywhere.

The area near the dam has become quite a tourist attraction, and the Shimoyama Village has developed a tourist and recreational facility called "Kokoi-no-Sato". In addition, fishing can be enjoyed on the dam lake, and boats are available for rent.
On holidays, there are a great number of tourists due to the recent recession. Although it was Golden Week, many of the cars stopped in the area had license plates with Nagoya numbers, with Mikawa at the top of the list.

Other facilities/observations
There is a parking lot, but all of them were full, so we parked at the top end. Come to think of it, this is the only dam where you can park at the top end. We had to go to the boat pier to use the restroom, but it was a bit far. It is strange that such a large dam, which has become a tourist attraction, does not have a PR exhibition hall. Is it because it is not a multi-purpose dam?

Comment
Please tell us about the accident situation of those who died in the line of duty at the time of construction. I was deeply moved when I saw the cenotaph for those who died in the line of duty. I bow my palm in prayer.

Unfortunately, we do not know the circumstances of the accident. However, I would like to express my gratitude for the sacrifices made by those people and for the fact that we are able to eat the crops produced by the farmers because the dam is used for irrigation.
