Nagakawa Canal and Matsushige Lock Gate

The Matsushige Lock Gate was built in 1930 and opened in 1932 to allow boats to pass between the Horikawa and Nakagawa canals, which had different water levels. It used a Stoney-type gate to control the water level inside the lock chamber, enabling boat navigation. Although it closed in 1976 due to declining boat use, it was preserved following public demand and designated as a cultural property in 1986 and an important structure in 1993 in Nagoya City.
