The Blue Line (ブルーライン, Burū Rain) is a rapid transit line serving Yokohama in Kanagawa Prefecture, Japan. It is the longer of the two lines in the Yokohama Municipal Subway system operated by Yokohama City Transportation Bureau, and is the second-longest subway line in Japan at 40.4 kilometers (25.1 mi) in length, surpassed only by the 40.7-kilometer (25.3 mi) long Toei Oedo Line in Tokyo. Unlike most metro lines in Japan, it uses third rail for power instead of overhead lines. It is the most recent newly built steel-wheel railway line in Japan to do so.
The Blue Line is divided into two operating segments: Line 3 from Azamino in Aoba-ku, Yokohama to Kannai, and Line 1 from Kannai to Shōnandai in Fujisawa. Local and rapid services each operate as a single service across both lines.
Following the opening of the Green Line on 30 March 2008, the line was nicknamed the "Blue Line". The line color is blue and the line symbol used in the station numbering is B.
