Tatsumi YosuiTatsumi Yosui

Also known as: Tatsumi Canal

A canal said to have been completed in 1632 by the townsman engineer Itaya Heishiro on the orders of the 3rd Kaga lord Maeda Toshitsune, built in response to a major fire that struck Kanazawa in 1631. It exploited the fact that its water source sat higher than the castle, using a technique called fuskoshi, an inverted siphon, to let water pressure alone push water up into the castle grounds.
