The Toei 6300 series (東京都交通局6300形) is an electric multiple unit (EMU) commuter train type operated by the Tokyo Metropolitan Bureau of Transportation (Toei) on the Toei Mita Line in Tokyo, Japan. Introduced into service on 23 June 1993, a total of 37 six-car trainsets (222 vehicles) were built by Kawasaki Heavy Industries and Kinki Sharyo between 1993 and 2000[1] to replace the non-air-conditioned Toei 6000 series.


The fleet consists of 37 six-car sets formed as shown below, with car 1 at the Nishi-Takashimadaira end.[2][3]

Car No. 1 2 3 4 5 6
Designation Tc1 M1 M2 T1 M1 Tc2
Numbering 63xx-1 63xx-2 63xx-3 63xx-4 63xx-5 63xx-6
Capacity (seated/total) 49/136 55/147 55/147 55/147 55/147 49/136

Cars 2 and 5 are each fitted with two lozenge-type pantographs.[2]


Seating consists of longitudinal bench seating with sculpted seat cushions, and 4-seat transverse bays are provided at the ends of cars.[3]


The first sets were delivered on May 1993, and entered revenue service from 23 June of the same year;[3] the original purpose of the Toei 6300 series was to replace the non-air-conditioned Toei 6000 series. In 2000, the third batch of the 6300 series was delivered for through-service operations into the Tōkyū Meguro Line as it was more economical to replace the remaining 6000 series units than to modify them.[4]
