The KiHa 35 series (キハ35), along with the similar KiHa 30 and KiHa 36 series, are Japanese diesel multiple unit (DMU) train types formerly operated by the Japanese National Railways (JNR) and JR Group of companies, and later operated by the private railway operators Kanto Railway and Mizushima Rinkai Railway. They were built from 1961 until 1966, and were widely used around Japan. Most units were withdrawn in 2012 with the exception of those used by private railways, which remained in service. Some were later operated by Philippine National Railways on Bicol Commuter Train since 2015, and on Metro South Commuter services since 2017.
