Introduction of Horiwari River

　With the development of Yokohama Port, the Horiwari River, completed in 1874, was used as a boat route connecting Yokohama Port and Negishi Bay from the Meiji era to the Showa era. Wharfs were lined up at the estuary, and lodgings, shipyards, and factories were lined up along the river, and it was said that the bustle was seen.

The event is introduced on the Horiwari River charming page.

　The Horiwari River is a population canal that diverts from Nakamurakawa near Kuraki Bridge and Ikeshita Bridge and pours into Negishi Bay.
　Bridge: From the upstream, Nakamurabashi, Tenjinbashi, Negishibashi, Sakashita Bridge, Isogobashi, Yahatabashi

　The Yokohama Green Environment Bureau Institute of Environmental Science conducts biological surveys in coastal waters in Yokohama.
　Of the creatures confirmed in the survey of the Horiwari River estuary and inner bay, the main creatures are introduced with photos.

You can see the survey report "Lives of the River and the Sea of Yokohama".

Along the river, there are various facilities that convey the history of Yokohama since the Meiji era. In addition, sports facilities are scattered, and schools for children are being implemented.

　Near the estuary, "Yokohama Pool Center" was set up in 1965, and many citizens enjoyed it, but business has been suspended since 2021 due to aging facilities.
　A part of the premises is used as the "Negishi Tennis Garden", and junior classes are also held by "Dunlop Indoor Tennis School Negishi".

In May 2022, a new hydrophilic facility "Horiwari River Isogo Pier" with a floating bridge on the Horiwari River was completed!
Please use it as a place where you can get close to the river!
　〇 Facility name: Horiwari River Isogo Pier
　〇 Facilities: Waterfront facilities, Ukisanbashi, unloading Sanbashi
　
In Kanagawa Prefecture, we are developing hydrophilic facilities in cooperation with town development in order to enhance the attractiveness of the town by utilizing the Ooka River water system rivers.
The hydrophilic facility also has a floating bridge and a unloading bridge, which is expected to be used for revitalizing water recreation, creating bustle in the town, and transporting goods in emergencies.
　

Ukisanbashi is locked with an electronic key for safety management. Advance reservations are required for use by the Kanagawa Prefectural Flood Control Office.
In the case of use, please make advance reservation from prefecture homepage.

In November 2010, it was certified as a civil engineering heritage by the Civil Society of Japan in 2010.

The Horiwari River, which was excavated in the early Meiji era and diverted from the Ookagawa River, played a major role in water transport and flood control measures in Yokohama City, and the long masonry revetment left a remnant of the time.

The certification system for civil engineering heritage selected by the Japan Society of Civil Engineers was established in 2000 with the aim of contributing to the preservation of historical civil engineering structures through the recognition of civil engineering heritage. In 2010, 27 structures nationwide, including the Horiwari River, were certified as "civil engineering heritage."
