The 285 series (285系 Nihyaku-hachijūgo-kei?) is an electric multiple unit (EMU) train type operated jointly by Central Japan Railway Company (JR Central) and West Japan Railway Company (JR-West) on the overnight Sunrise Izumo and Sunrise Seto limited express services in Japan. These EMUs were introduced from 10 July 1998 to replace ageing locomotive-hauled "Blue Train" coaches which once operated on separate Seto and Izumo services between Tokyo, Shikoku and the Sanin region.
The trains are finished in a livery of "Morning Glow" red and "Morning Mist" beige with "Sun Rise" gold lining.
As of 1 April 2015[update], the fleet consists of five sets, numbered I1 to I5. I1 to I3 are owned by JR-West, and are classified 285-0 series. Sets I4 and I5 are owned by JR Central, and are classified 285-3000 series (the individual cars are numbered in the 3000 range). All sets, I1 to I5, are composed as follows, with two motored ("M") cars and five non-powered trailer ("T") cars. Car 7 and 14 is at the Tokyo (eastern) end.
The cars of JR Central sets I4 and I5 are numbered in the -3000 series. The motor cars are each fitted with one WPS28A single-arm pantograph. The motor cars in sets I1 and I3 each have two.
Each car includes toilet facilities.
