Series 30000 has been in service since 2008. They have rounded aluminum body, with blue and green gradation. Since they do not have front doors, they do not run into Yurakucho and Fukutoshin Metro. The body structure is based on A-train by Hitachi. As they are built, series 101 and 301 are being replaced.
