On 21 June 2019 JR West announced the introduction of new 271 series trains on Haruka limited express services. The order for 18 cars was worth 6 billion yen. The first train was unveiled at the Kinki Sharyo head office on 10 July 2019. The trains entered revenue service on 14 March 2020, but due to the outbreak of the COVID-19 pandemic and the subsequent drop of air travelers, JR West decided to postpone lengthening the Haruka trains to nine cars.Currently, all Haruka trains are still formed in six car sets, with nine-car services intended to resume when air travel goes back to normal. The sets re-entered service on 13 March 2021 with the introduction of that year's revised timetable when various Haruka sets resumed 9-car operation.
