History
Isezaki-chōjamachi Station opened on 16 December 1972 as part of the first segment of the Yokohama Municipal Subway (today's Blue Line), built on land created by filling in the former Yoshida River where Senshu Bridge once stood. Construction was set back when a damaged sewer manhole during Typhoon No. 20 of 1972 flooded the nearly complete station on 16 September with roughly 20,000 cubic metres of muddy water, submerging signal and CTC equipment and pushing the opening back by a month. The station became an intermediate stop when the line was extended to Yokohama on 4 September 1976, and on 26 May 2007 platform-edge doors entered service. Located adjacent to the Isezaki-chō shopping area, the station carries number B16.
