Fuji Minobu class 210 electric locomotive, Japan

This was a Japanese DC Bo-Bo electric locomotive operated by the Fuji Minobu Railway and later the Japanese National Railways from June 1928 to 1973. Three were built in June 1928 by Hitachi for the Fuji Minobu Railway and entered service the same year. The type was similar to the ED15 class

With the Fuji Minobu Railway's nationalization on 1 May 1941, the engines were acquired by the Japanese National Railways, reclassified as the JNR Class ED21 and renumbered ED21 1, ED21 2 and ED21 3. On the JNR, they were used on the Iida and Ōito Lines. ED21 2 would be loaned to the Sangi Railway to transport construction materials for the Kurobe Dam. ED21 1 was scrapped in 1959, while ED21 2 and 3 were withdrawn in 1973.

None were preserved.
