on loan to Sentetsu at the end of the war were in South Korea after the division, where they were put into service by the Korean National Railroad. The KNR classified these 미카1 (Mika1) class, and at least seven of these were taken up by the KNR, retaining their original road numbers: In addition, twelve more of these were delivered to South Korea from Japan after the war; these were numbered 미카1-1101 through 미카1-1112. 1101 and 1102 are known to have been built by Hitachi in 1947, whilst 1104 through 1109 were built by Kawasaki in 1950. Korean National Railroad 미카5 (Mika5) class After the partition of Korea, the US military administration in Korea ordered the construction of new Mikako type locomotives in Japan for use in South Korea; 49 were delivered, of which 33, numbered in the 9400 series, were taken up by the US Army Transportation Corps. The original assignments of the other eleven locomotives is unclear. After the end of the Korean War, these were passed on to the KNR. In addition, UN forces captured a number of Mikako-type locomotives that had been provided to North Korea from China during the war; these, along with a few Mikako type locomotives that remained in the South after the partition, were grouped together with the 49 built in Japan between 1947 and 1951, and the KNR grouped these 56 locomotives into 미카5 class and numbered them 미카5-1 through 미카5-56. A further twenty were built in Japan in 1952 (ten by Nippon Sharyō, five each by Hitachi and Kisha Seizō), but these were never delivered to South Korea. Due to the different standards in Japan and Korea (track gauge, axle load, clearance profiles), these were not taken up by the Japanese National Railways, and instead sat unused for many years until finally being scrapped, brand-new, in 1965. Several of the 미카5 class have been preserved. Preservation China At the China Railway Museum in Beijing: JF1 304 - named "Mao Zedong"; previously Mantetsu ミカイ304.
