The body design uses a new lightweight corrugated stainless steel construction.[4] These trains use the same AFE (Automatic Field Excite) chopper control as the earlier Tobu 9000 series trains, bolsterless bogies.[6]
Total number of vehicles built: 104[4]

Trains are formed as follows, with six motored ("M") cars and two non-powered driving trailer ("Tc") cars.[3]

Three eight-car sets (21871 to 21873) were introduced from 25 March 1997 to cope with an increased service frequency. These sets feature three-door cars throughout, and also LED destination indicators.[4] These sets have VVVF control.[1]
