Formation
As of 1 April 2013, the fleet consists of three eight-car sets, formed as shown below, with six motored (M) cars and two trailer (T) cars, and car 1 at the southern end.

The "M1" cars each have two pantographs, and the "M1'" car has one.

Interior
Passenger accommodation consists mostly of longitudinal bench seating, with some transverse seats at the car ends. The end cars each have a wheelchair space. The 1st-batch sets, 9101 and 9111, originally had public phones located in cars 3 and 6, but these were removed in 1997.

History
The first two sets, 9101 and 9111, were built by Nippon Sharyo in Toyokawa, Aichi, and delivered in 1994, ahead of the extension of the Hokuso Line from Chiba New Town Chūō to Inzai-Makinohara in 1995. A third, 2nd-batch set, 9121, was delivered in 2000, coinciding with the extension of the line from Inzai-Makinohara to Inba-Nihon-Idai.
