This gate was built in Keicho Era, and the Masugata stone wall was constructed by feudal load of Ou (current Tohoku Region) in 1629. According to 'Edo-jo Gaikaku Gomon ezu (Illustrated Outer Gates of Edo Castle)',a wooden bridge which was Masugate-mon Gate with watariyagura-mon Gate and Korai-mon Gate had been before this Gate. From inside of the stone wall, wooden bridge pier which consist of a set of three wooden stakes, and abutment stone wall were found during the stone bridge repairing work.
In the Early Meiji Period, wooden bridges from castle gates begun to be replaced to stone bridges, as symbol of modernization of Tokyo. In 1877 Tokiwabashi Bridge was rebuilt to double arch stone bridge with stone of Koishikawa-mon Gate Stone Wall. This bridge has sidewalks and car lanes separated from each other, which was rare at that time. With marble newel post of bridge, granite surface and smart designed bridge handrail, it showed civilization and enlightenment.
