Watarika-weir, Oide (Kumamoto City, Chuo Ku)

Watarika-weir is amazing. It was not just a spot for its scenery, but a place where one could really feel the precision of Lord Kiyomasa Kato's town planning.
This historic weir has played an important role in choking off the flow of the Shirakawa River and supplying water to the Kumamoto Plain. Its distinctive feature is its shape, which juts out at an angle to the river, which shows the high level of advanced civil engineering technology of the time. Whenever it was damaged by floods or confidence, it was repaired, and even today, it continues to supply water for agriculture and other functions. It is easy to see why Lord Kiyomasa became a god. It is such a relic.
