Future developments

In 2021, plans were announced to branch the Yurakucho line at Toyosu Station, traveling north for 4.8 km connecting up to Sumiyoshi Station. This branch line, expected to be in service in the mid-2030s, will connect Sumiyoshi Station with the region south of it. A branch line from Toyosu Station has been planned since the early 1980s, heading north via Kameari Station (on the Jōban Line) to Noda in northwest Chiba Prefecture.
