中浦水門, Coastal sluice in Matsue and Sakaiminato, Japan
The Nakaura Sluice Gate stretches 414 meters across the waterway, featuring ten double-roller gates and three navigation locks of different widths.
Built in 1974 for 9 billion yen, the sluice controlled water flow between Lake Nakaumi and the Sakai Channel until its removal in 2009.
The structure represented Japanese water management technology, connecting the communities of Matsue and Sakaiminato while supporting local agriculture.
The sluice operation included a road bridge that connected the two cities until 2004, when the Ejima Bridge replaced its transportation function.
Despite its initial purpose for freshwater conversion and agricultural development, the sluice was removed after 35 years at a cost of 9.4 billion yen.
