Based on the earlier 205 series design, the 207-900 series was a prototype built as the first VVVF-controlled EMU operated by JNR.[2] The 207 series built later by JR West bears no relation to this train.[3]
The train used adjustable voltage/adjustable frequency (AVAF) inverters and induction motors using gate turn-off thyristor (GTO) components.[4]

History
The train was delivered to Matsudo Depot in November 1986.[3]
It was withdrawn from service in 2009 following the introduction of new E233-2000 series EMUs, and a final "Sayonara" service was run on 5 December 2009.[5] The train was transferred to Nagano on 5 January 2010 for scrapping.[6]
