The 737 series (737系) is an AC electric multiple unit (EMU) commuter train type operated by Hokkaido Railway Company (JR Hokkaido) on services in the Sapporo area of Hokkaido, Japan, since 20 May 2023. The type replaced the fleet of KiHa 143 diesel railcars operated on the Muroran Main Line. The trainsets mark the return of local EMU services on the Muroran Main Line since the retirement of the 711 series from these services in October 2012.[1]
The 737 series is the first commuter train type operated by JR Hokkaido to allow for driver-only operation.[2][3]

Development and design
The 737 series is the first aluminium-bodied production rolling stock operated by JR Hokkaido (the front ends are made of steel). Its adoption follows the development of the experimental 735 series (introduced in 2012), which was developed to test the suitability of aluminium bodywork in cold-weather conditions. The weight savings brought on by aluminium were also taken into consideration, as the equipment required to support driver-only operation would otherwise lead to a significant increase in weight.[4]
The sets are painted in a light pink livery inspired by cherry blossoms; the front end is painted black, with green and yellow accents.[5]
Internally, the sets use longitudinal seating throughout. The seats are covered in purple moquette with a dotted design, which JR Hokkaido states was inspired by the blooming flowers in the Hokkaido region. Car 2 features a toilet. The floor height is 19 centimetres (7.5 in) lower than that of the KiHa 143 railcars they will replace.[5]

Operations
The 737 series sets operate between Tomakomai and Muroran stations on the Muroran Main Line; they will replace the fleet of KiHa 143 diesel railcars,[6][7] in addition to displacing some H100 series diesel-electric railcars,[8] the latter of which had also been planned to replace all local trains on the Furano Line.[9]
The 737 series also entered service on the Hakodate Main Line (Iwamizawa – Asahikawa) from 16 March 2024, with this series alongside H100 series DEMUs replacing older 721 series EMUs and other diesel cars previously operated in this section.[10]
All sets are based at Sapporo depot.[8]
