A six-car set being delivered in July 2001

The first set, 31601, was delivered in November 1996, with the first trains entering service on 25 March 1997.[1] Initially used primarily on Tobu Isesaki Line services, they were introduced on through-running services to and from the Tokyu Den-en-toshi Line via the Tokyo Metro Hanzomon Line from March 2003.[1]

Transfer to Tojo Line

Permanently coupled sets 31401 and 31601 undergoing driver training on the Tojo Line, April 2011
Permanently coupled intermediate driving cabs of cars 36601 and 31401, April 2011

From January 2011, pairs of four- and six-car sets were transferred to the Tobu Tojo Line, commencing with sets 31601 and 31401.[3] These sets entered revenue service from 13 June 2011 following modifications at Shinrinkōen Depot to form a permanently coupled 10-car set with control equipment and skirts removed from the two intermediate driving cabs.[4]
