History
The Sakura-dōri Line was first envisioned in the Urban Transportation Council Report No. 14 (1972) as an underground line running from Nakamura Kuyakusho to Imaike, and was intended to relieve the central portion of the Higashiyama Line, which in the late-1970s operated with a crush load capacity of 250% during rush hour.

The line was opened on 10 September 1989 between Nakamura Kuyakusho and Imaike. Automatic train operation (ATO) using a single driver commenced on 16 February 1994, and the line was extended from Imaike to Nonami on 30 March 1994.

From Nonami, the line was extended further east to Tokushige, in Midori-ku, on 27 March 2011. This extension also involved building a new depot near Tokushige Station, which replaced the previous depot located near Nakamura Kuyakusho Station. There is a plan to extend the line even further, somewhere in Toyoake City or Toyota City. There is also a plan to extend the line to opposite direction, from Nakamura Kuyakusho to somewhere in Ama.
