The 227 series design is based on the earlier 225 series, with lightweight stainless steel bodies.

The 227-0 series fleet consists of 276 vehicles (42 two-car sets and 64 three-car sets), which were delivered from autumn 2014 for test running and driver training before entering revenue service initially on the Sanyo Main Line between Shiraichi and Iwakuni, replacing ageing JNR-era 115 series EMUs.^[1] The trains were also intended to displace 115 series EMUs on the Kure Line and Kabe Line.^[2] The entire fleet was delivered by February 2019.^[8]

The fleet entered revenue service from 14 March 2015. They were the first new trains to operate in the Hiroshima area since the 113-3000 series, which was introduced near the end of JNR; trains introduced since the 113-3000 series were inherited from the Kansai area.^[9]: 21 The last sets of this sub-series delivered were 2-car sets S41 and S42 in February 2019. ^[10]

In January 2022, it was announced that the 227-0 series would undergo a trial for platform-side cameras. The cameras would be activated on the right side of the train relative to the direction of driving.^[11]

Set A65 was formed in 2022 by combining two cars (KuMoHa 226-11 and MoHa 226-11) from three-car set A11 and one car (KuMoHa 227-33) from three-car set A33.^[12]

The planned 56-car fleet (28 sets of 2-car units) was completed by the end of September 2019,^[33] and would displace all 105 series and 117 series trains on the two lines by Spring 2020. Once the order is complete, the trains would have smart card readers on board, expanding ICOCA acceptance to all JR West service in Nara prefecture and on Wakayama Line.^[4]

The fleet entered service from 16 March 2019.^[34]

The 227-500 series will consist of 13 two-car sets and 25 three-car sets (101 cars in total), and were first announced by JR West in May 2022 for use on rail lines serving Okayama and Bingo, such as the San'yō Line.^[8][45][46] Designated as 227-500 series, the first three sets were delivered from Kinki Sharyo in February 2023.^[46] The series was given the brand name Urara (うらら) owing to a naming contest run by JR West.^[46] The sets carry a pink livery, which is associated with cherry blossoms as well as the softer climate experienced along the lines in which these trainsets will be running.^[8]

The first of these sets entered revenue service on 22 July 2023 on the Sanyo Line and the Hakubi Line.^[47] As of 20 January 2024, this subseries operates on the Sanyo Main Line (Himeji - Mihara), the Hakubi Line (Okayama - Niimi), the Uno Line and the Honshi–Bisan Line (Chayamachi - Kojima).^[48]
