The 205 series (205系, 205-kei) is a DC electric multiple unit (EMU) commuter train type introduced in 1985 by Japanese National Railways (JNR), and inherited by JR East and JR West after the privatization two years later. It is currently operated by East Japan Railway Company (JR East), West Japan Railway Company (JR West), Fuji Kyuko (Fujikyu) in Japan and KAI Commuter in Indonesia. Some of them were re-designated as Fujikyuko Series 6000.
