History

The first 3700 series sets were introduced in 1991, replacing the original 3000 series trains. The first six-car sets were delivered in 2000. Sets from the 6th batch onward had restyled front ends with the headlights located near the roof. Two eight-car sets were leased to the Hokuso Railway becoming Hokuso 7300 series sets 7808 and 7818, supplementing the two 7300 series sets owned by the Hokuso Railway.
In 2017, eight-car set 3738 was converted and renumbered to become Chiba New Town Railway 9800 series set 9808, owned by the Chiba New Town Railway and operated by the Hokuso Railway.
