The Sapporo Municipal Subway 6000 series (札幌市交通局6000形) was a DC electric multiple unit (EMU) rubber-tyred metro train type operated by Sapporo Municipal Subway on the Tōzai Line in the city of Sapporo, Japan, from June 1976 to August 2008.

[1] The trains are built by Kawasaki Heavy Industries and use chopper control with a reverse conducting thyristor.

The 8300 series cars that were inserted later used a variable-frequency drive, provided by either Mitsubishi or Hitachi.

Passenger accommodation consists of longitudinal bench seating throughout, with a wheelchair space in each car.

The first prototype cars were manufactured in 1975, and had a shape remarkably similar to that of the older 2000 series, followed by 20 more full-production sets in 1976.
