The 400 series (400系^?) is a Japanese Shinkansen high-speed train type introduced in 1992 for the start of Tsubasa services on Japan's first Mini-shinkansen line, the Yamagata Shinkansen branch from the main Tōhoku Shinkansen.

Clearances are much reduced compared to previous Shinkansen lines, and thus the 400 series units are much narrower than previous Shinkansen trains. At shinkansen stations (i.e. high-speed line stations), steps extend from beneath the doors to bridge the otherwise wide gap between the trains and platforms. Seat pitch is also reduced in the non-reserved cars.

400 series in original colour scheme, 1999

Styling wise, the 400 series is another to have an aircraft-style nose with a pointed nosecone. Originally they were painted a medium silver grey with a darker roof and area around the cab windows and underframe, but they were refurbished and repainted between 1999 and 2001, with a higher area of dark bluish-grey on the underside, coming up almost to the side windows, and separated from the silver grey with a green stripe. The dark grey on the roof and around the cab windows is gone.

They were originally six-car sets, but a seventh car was added in 1995 to each to reflect increased popularity of these services.

The fleet of twelve 400 series trains were withdrawn between December 2008 and summer 2009 to be replaced by new E3-2000 series trains.^[1]
