History
A train celebrating the extensions to Shin-Yokohama and Maioka in March 1985

In 1965, construction of Line 1 and Line 3 began. The subway was inaugurated on 16 September 1972, when the 5.2 km long initial section of Line 1 opened between Kami-Ōoka and Isezakichōjamachi stations. On 4 September 1976, Line 1 was extended in both directions: 2.8 km and 2 stations to the southwest (from Kami-Ōoka to Kaminagaya), and 0.7 km and 1 station to the north (from Isezakichōjamachi to Kannai); the 2.8 km long initial section of Line 3 between Kannai and Yokohama also opened that same day and through services between Line 1 and Line 3 began.

On 14 March 1985, two extensions opened: a 7.0 km, 5 station extension of Line 3 from Yokohama to Shin-Yokohama, and a 2.0 km, 2 station extension of Line 1 from Kaminagaya to Maioka. Line 1 would be extended by one station to Totsuka (a distance of 1.7 km) on 27 August 1989; a temporary station was in operation at that location from 24 May 1987 until that date. The most recent extension of Line 3, a 10.9 km section from Shin-Yokohama to Azamino opened on 18 March 1993. The final 7.4 km section of Line 1 from Totsuka to Shōnandai opened on 28 August 1999.

From July 2015, limited-stop "Rapid" services were introduced on the line, with approximately two services operating per hour during the daytime off-peak. Journey times over the entire length of the line were reduced by up to 10 minutes from the 1 hour 7 minutes taken by all-stations services.[3] From 4 March 2017, the intervals between rapid trains was decreased to 20 minutes
