History

The first set was introduced in 1992 for inter-running with the Tokyo Metro Yurakucho Line. All sets are in 10-car fixed formations. Construction continued until 1998. Sets from 6156 onward were built with no door-pocket windows.^[2]

Sets 6108 to 6117 and 6151 to 6158 include ATC for use on the Tokyo Metro Yurakucho Line and Seibu Yurakucho Line. Between 2006 and 2007, sets 6103 to 6107 were also modified with ATC for use on the Tokyo Metro Fukutoshin Line. These sets are distinguished by the addition of white front-end surrounds.^[2]
