[1] The Tatsumi Canal was completed in 1632 by the third daimyō of Kanazawa Domain, Maeda Toshitsune.

[2] Despite the long distance and technical difficulties in building the canal, it was completed in less than a year.

At that time, a wooden trough was buried to guide water to Kanazawa Castle.

The canal is regarded as a valuable artifact of civil engineering technology during the Edo period, and the 8.7 kilometer portion covered by the National Historic Site designation in 2010 is centered on the upper and middle reaches.

This portion is about 30 minutes by car from Kanazawa Station on the JR West Hokuriku Main Line.
