Dempo Sluice Gate is a water gate located in Dempo, Konohana Ward, Osaka City, built at the mouth of the now-vanished Dempo River. In 1873, as part of improvements to the Yodo River, the Dempo Lock Gate (Dempo Kōmon) was completed to regulate water levels. Later, rapid industrialization led to severe land subsidence, and landfill work on the Dempo River began in 1951. In 1964, the lock gate was replaced by the present water gate. Today, only the portion where the former Dempo River flows into the Shin-Yodo River remains as a fishing harbor. Dempo is one of the few fishing ports within Osaka City, and the Osaka City Fisheries Cooperative is based here. Nearly 100 fishers operate in Osaka Bay and the Yodo River, shipping their catch daily to the Central Wholesale Market. The Dempo Sluice Gate also marks the confluence of the Dempo River and the Shin-Yodo River, and there is a yacht harbor nearby. The origin of the name “Dempo” has several theories; one says it means “the place where Buddhism (the Dharma) was transmitted.” Nearby attractions include Shōren-ji Temple of Nichiren Buddhism, the former Konoike main residence built in 1910 and listed among the Architectural Institute of Japan’s notable buildings, and Karasu-no-miya Shrine, dedicated to the three-legged sacred crow Yatagarasu and designated as a Registered Tangible Cultural Property of Japan.
