The 285 series (285系?) 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]


There are five sets, numbered I1 to I5. I1 to I3 are owned by JR West, and are sometimes referred to as the 285-0 series. Sets I4 and I5 are owned by JR Central, and are sometimes known as the 285-3000 series (the individual cars are numbered in the 3000 range). All sets, I1 to I5, are composed as follows.[1]

Car No. 1/8 2/9 3/10 4/11 5/12 6/13 7/14
Numbering KuHaNe 285 SaHaNe 285-200 MoHaNe 285 SaRoHaNe 285 MoHaNe 285-200 SaHaNe 285 KuHaNe 285
