The 285 series (285系, 285-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.[1]
