First electric multiple unit service in Japan

On June 16, 1903, Japan's Kobu Railway introduced electric multiple unit trains between Iidamachi and Nakano stations in Tokyo, representing Asia's earliest regular electric rail service. Powered by overhead lines at 600V DC, the wooden cars featured advanced Westinghouse equipment imported from the United States. This innovation addressed urban congestion and smoke issues from steam locomotives, paving the way for Tokyo's extensive subway and commuter network. Key figures included engineer Yasujiro Shima. The service boosted ridership dramatically and influenced national electrification standards still used today.
