Design
Trains have unpainted stainless steel bodies. Each motored car has one motored bogie. The first batch of trains, branded "Red Wing", have logos applied on the sides of the body and on the prominent anti-fall plates on the front ends, which inspired the name.

Passenger saloons use LED lighting, and the trains are equipped with universal access toilets and wheelchair spaces. They are also equipped with LED passenger information displays.

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

227-500 series 

The  series consists 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. Designated as 227-500 series, the first three sets were delivered from Kinki Sharyo in February 2023. By September 2024, the entire fleet was delivered. The series was given the brand name  owing to a naming contest run by JR West. 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.

The first of these sets entered revenue service on 22 July 2023 on the San'yō Line and the Hakubi Line. As of 20 January 2024, this subseries operates on the San'yō Line (Himeji - Mihara), the Hakubi Line (Okayama - Niimi), the Uno Line and the Honshi–Bisan Line (Chayamachi - Kojima).
