Of all Mika classes in Korea, including the 54 on loan to Sentetsu from Mantetsu and 13 owned by private railways, 131 went to the KNR and 292 to the Korean State Railway. Note that this number does not include the 14 Mantetsu Mikai and 8 Mikaro-class locomotives that were assigned to Mantetsu's Rajin depot in 1945 and were subsequently taken over by the Korean State Railway.
Despite the DPRK government's extensive anti-Japanese propaganda, the railway nevertheless continues to use the "Mika" name officially for these locomotives even though it refers to the Japanese emperor.
