For this report, we arrived from Kanazawa via Route 157. The area around the dam is rich in tourist attractions, such as the Hakusan Super Ring Road, so the dam is also a tourist attraction and has a drive-in element.

It is the tallest dam I have been to so far. However, I personally prefer arched concrete dams to rockfill dams, so I felt that something was still missing.

The gate was off limits and there was even an intrusion alarm system. I managed to avoid it and took some photos.
