The Asia Express (Japanese: アジア号, romanized: Ajia-gō, simplified Chinese: 亚细亚号; traditional Chinese: 亞細亞號; pinyin: Yàxìyà hào) was a super express passenger train operated by the South Manchuria Railway (Mantetsu) from 1934 until 1943. This limited express, which began operation in November 1934 and was Mantetsu's most iconic train, operated in Manchukuo between Dalian and Changchun, and was extended to Harbin in 1935.
