Akita Shinkansen
The full-production trainsets built from 1996 for the Akita Shinkansen were 5-car sets, but sixth cars were added by the end of 1998. 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. This lease ended on 21 March 2010 with the dissolution of Akita Shinkansen Sharyō Hoyū.
