The KiHa 281 series (キハ281系?) is a tilting diesel multiple unit (DMU) train type operated by Hokkaido Railway Company (JR Hokkaido) on Super Hokuto limited express services in Hokkaido, Japan since 1994. They were the first tilting trains to be operated by JR Hokkaido.
The fleet of 27 cars is normally formed into seven-car sets for use on Super Hokuto limited express services operating between Hakodate and Sapporo, and formations are sometimes lengthened to eight cars during busy periods.
7-car sets are normally formed as follows, with car 1 at the Sapporo end. Car 3 is a Green (first class) car.

Two pre-production cars, KiHa 281-901 and KiHa 281-902, were delivered from Fuji Heavy Industries in January 1992 for evaluation and testing. A pre-production intermediate car, KiHa 280-901, also built by Fuji Heavy Industries, was delivered in October 1992 to form a 3-car set. The first two cars delivered used the same roller-tilting mechanism on the bogies as used on the earlier JR Shikoku 2000 series DMUs, whereas the third car delivered used a bearing-guide system. The pre-production 3-car train underwent test-running to evaluate the two different systems in the harsh winter conditions of Hokkaido. The later bearing-guide tilt mechanism proved superior, and this system was used on subsequent production trains delivered from 1993.
Entry into service
The KiHa 281 series entered revenue service from the start of the revised timetable on 1 March 1994. The new tilting trains operated at a maximum speed of 130 km/h (81 mph), reducing the journey time for the 318 km distance between Hakodate and Sapporo to 3 hours, shaving 30 minutes off the journey time for Hokuto services operated by KiHa 183 series DMUs.
The original "HEAT281" logo on cab sides of the pre-production trains was changed from "Hokkaido Experimental Advanced Train" to "Hokkaido Express Advanced Train" with the arrival of the production cars. This logo was later changed to "Furico 281" to match the style used on the newer KiHa 283 series trains.
