E3 Series Shinkansen

Later versions of the E3 series were also introduced for use on Yamagata Shinkansen Tsubasa services. Both "mini-shinkansen" lines join the Tohoku Shinkansen, providing services to and from Tokyo.

Design
This shinkansen design was originally the Akita Shinkansen E3 series trains was overseen by industrial designer Kenji Ekuan. Like the 400 Series Shinkansen, these trains are built to a smaller loading gauge than mainline Shinkansen trains—the width and length of each car is reduced to fit on the narrower clearances of the "mini-shinkansen". Doorway steps fold out to bridge the gap between the narrow body and the platform at regular shinkansen stations.

Pre-series set
A pre-series 5-car set, numbered S8, was delivered from Kawasaki Heavy Industries to Sendai Depot in March 1995 for extensive testing. It was modified to full-production specifications in March 1997 ahead of the start of Akita Shinkansen services.

Until it was augmented to six cars in 1998, the pre-series was formed as follows, with scissors-type pantographs on cars 12, 13, and 14. Set R1 was withdrawn following its final revenue run on 20 July 2013.

A total of 26 Akita Shinkansen sets were in service by the end of 2005. Sets R1 to R16 were leased by East Japan Railway Company (JR East) from the owning company, , a third-sector company jointly owned by JR East and Akita Prefecture.
