The 413 series (413系, 413-kei) is a Japanese dual-voltage (1,500 V DC and 20 kV AC 60 Hz) electric multiple unit (EMU) train type first introduced by Japanese National Railways (JNR) in March 1986, and later operated on local services on the Hokuriku Main Line by the West Japan Railway Company (JR-West) from 1987 and also by the third-sector railway operating company Ainokaze Toyama Railway from March 2015. The units were built by re-using the underframes, bogies and electrical equipment from former and express-type EMUs with new suburban type bodies based on the design of the EMUs introduced in 1978.
