The Tōyō Rapid 1000 series (東葉高速鉄道1000形) was an electric multiple unit (EMU) commuter train type formerly used to operate on the Tōyō Rapid Railway Line, an extension of the Tokyo Metro Tozai Line in Tokyo, Japan. A total of twelve ten-car sets were converted in 1995 from former TRTA 5000 series sets. They were retired from service in December 2006, replaced by the Tōyō Rapid 2000 series.

The last three sets to be withdrawn (1061, 1081, 1091) were shipped to Indonesia in 2006 and 2007, where they are operated by KRL Jabodetabek on suburban services in the Jakarta area. They were retired from service in 2019, replaced by 205-0 and 205-5000 series.

Overseas operations

Three ten-car sets (1061, 1081, and 1091) were shipped to Indonesia from 2006 for use on suburban services operated by Kereta Commuter Indonesia (previously called "KA Commuter Jabodetabek" or "KRL Jabotabek") in Jakarta from January 2007. The sets were initially reduced to eight-car formations, but former set 1061 was withdrawn in December 2015, and set 1091 was split to donate a pair of intermediate cars to lengthen set 1081 to ten cars and also to former Tokyo Metro 5000 series set 5817 to lengthen that set to ten cars also.

Since 2019, with the increasing number of the newer JR East 205 series EMU, set 1081 was retired from service.
