The 400 series (400系) was a Japanese Shinkansen high-speed train type operated by East Japan Railway Company (JR East) between 1992 and 2010 on Tsubasa services on Japan's first mini-shinkansen line, the Yamagata Shinkansen branch from the main Tohoku Shinkansen.
The fleet of 400 series trains was leased by JR East from the owning company, Yamagata JR Chokutsū Tokkyū Hoyū Kikō (山形ジェイアール直通特急保有機構(株)), a third-sector company jointly owned by JR East and Yamagata Prefecture.[1]
They were originally six-car sets, but a seventh car (type 429) was added in 1995 to each set due to the popularity of the new Tsubasa services.
