Design
The trains are built by Kawasaki Heavy Industries to a "retro-future" concept, with black front ends intended to evoke images of a steam locomotive.[3] The exterior livery includes orange and green highlights evoking the satsuma oranges and olives for which the region is famous.[2] Each vehicle is built at a cost of approximately 250 million yen, financed partially by national infrastructure investment subsidies.[2] The trains operate at a maximum speed of 130 kilometres per hour (81 mph) in service, although they have a maximum design capability of 140 km/h (87 mph).[3] Tilting capability enables the trains to negotiate curves with a radius of 600 metres (2,000 ft) or more at a speed 30 km/h (19 mph) higher than the limit for conventional non-tilting trains.[3]

History
The first two pre-series sets, E11 and E12, were delivered to Takamatsu Depot from the Kawasaki Heavy Industries factory in Kobe in February 2014.[5] Test running commenced in March.[6] The trains entered service on Ishizuchi limited express services between Takamatsu and Matsuyama on 23 June 2014.[7]
The next four full-production sets (three-car sets E1 and E2 and two-car sets E13 and E14) were delivered from Kawasaki Heavy Industries in October 2015.[8]
In 2017, JR West borrowed two 8600 series sets to test the feasibility of pneumatic tilting on the Hakubi Line[9][10] for a new rolling stock type for its Yakumo limited express services. The pneumatic tilting system proved unsuitable for the line, and JR West decided that the new rolling stock would use a pendular tilting system instead.[11]
Three-car set E3 was delivered from Kawasaki Heavy Industries in January 2018,[12] entering service on 14 February.[13]
