The E3-Series Shinkansen is a high-speed EMU in Japan. It was built from 1995–2010 for the Komachi service on the Akita line owned by JR East.


Very similar in design requirements to the 400-Series, the E3 was designed to be narrower and lighter than main-line Shinkansens for the Akita line, that was up-graded and re-gauged to fit the rest of the Shinkansen network by 1997.


The first E3-Series to be made was a pre-production unit numbered S8. This 5-car set was delivered from Kawasaki Heavy Industries in March 1995 for testing. By March 1997 it was modified to production standards.

R (E3) setsEdit

These 5-car sets, later modified to 6-car sets in 1998, were the first production sets. They were numbered R1 to 16, and produced between 1996 and 2005. Cars 12 and 15 held the pantographs.

E3-1000 setsEdit

Three of these 7-car sets were built between 1999 and 2005. Numbered L51-53, they work on the Yamagata line. Cars 12 and 14 held the pantographs.

E3-2000 setsEdit

These 7-car sets were built between 2008 and 2010. Numbered L61 to 72 they are to have replaced the 400-Series completely by 2009. Cars 12 and 14 hold the pantographs.
