The Tobu 5000 series (東武5000系, Tōbu 5000-kei) was a DC electric multiple unit (EMU) commuter train type operated by the private railway operator Tobu Railway in Japan between 1979 and 2006.

[1] These four sets were also subsequently modified with air-conditioning between July 1984 and March 1985.

[3] The trains were removed from regular service in late 2006, with a sayonara final run on 16 December,[4] and were entirely withdrawn by February 2007.

13 six-car 5070 series sets (78 vehicles) were built between June 1984 and March 1986 by modernizing former 7800 series EMU cars with new 8000-series-style bodies and air conditioning.

[5] The fleet operated on the Noda Line, but were gradually replaced from 1997 by six-car 8000 series EMUs displaced by the arrival of new 30000 series EMUs on the Tobu Isesaki Line, with the entire fleet withdrawn from service by the start of the revised timetable on 19 October 2004.
