There are 13 subway lines in Tokyo, and they currently carry more than 8 million passengers per day. Many of the subway lines also link up with commuter lines and extend their service to the suburbs. Although transportation technology is moving into the space age, Japan continues to recognize the many advantages of rail transport, including its convenience, energy efficiency, low pollution, and safety. Yurikamome, a new unmanned transport system, was inaugurated between Shimbashi and Ariake stations in Tokyo, in 1995. Commercial operation of a linear-motor train is foreseen for the near future.
Tests are underway.
Now in use is a linear-type motor car in subways in Tokyo and Osaka.
