Range: Often house mice occur arable lands, pastures, coastal sand dunes, salt marshes and scrubby road verges (Macdonald & Barrett 1993). However, feral house mice are extremely rare in Korea (Won 1967). On the Korean Peninsula and islands, the distribution of M. musculus is closely associated with human habitations (Jo et al. 2012; Fig. 126).

Remarks: Suzuki et al. (2013) identified five distinct clades of house mouse; musculus in northern Eurasia; castanes in India and southeast Asia; an unspecified Nepali clade; domesticus in western Europe; and gentilulus in Yemen. Populations from Korea belong to the musculus clade. House mice in Korea originate from multiple and non-coincidental dispersals from the West (Suzuki et al. 2013). Three subspecies, M. m. yamashinai Kuroda, 1934 on the peninsula, M. m. molossinus Temminck, 1845 on Jeju Island and M. m. utsuryonis Mori, 1938 on Ulleung Island, have been described from Korea. Some taxa hybridize with different subspecies, including the Japanese house mouse (M. m. molossinus) (Yonekawa et al. 1998). DNA analysis supported either M. m. molossinus or M. m. musculus as the primary subspecies of house mouse for all of northeastern Asia, including Korea, northern China and Japan and therefore, Korean house mice are polymorphic (Yonekawa et al. 1998, Musser & Carleton 2005).
