It roosts in various types of structural objects such as tree cavity, under bark, foliage and cave (Kawai 2015a). In Russian Far East it is known to make day roosts under the leaves of large herbaceous plants, like Petasites (Red’kin and Ganitsky, 2003, E. Dunayev pers. comm. 2018). Parturition occurs from late May to late July (Funakoshi et al. 2009). The maternity colonies show very frequent roost-switching (Fukui et al. 2012). In winter, this species may roost in tree cavities and inside snow (Kawai 2015a).

Restricted to southern part of Russian Far East, the Korean Peninsula, Sakhalin, Kunashir Island, and Japan. Within Japan, it has been recorded from Hokkaido, Honshu, Shikoku, Kyushu, the islands of Tsushima, Yaku-shima and Iki (Kawai 2015a). In China, it has been reported from the provinces of Nei Mongol, Jilin and Heilongjiang (Smith and Xie 2008), but this needs verification, it is possible that these records should be attributed to another Murina species (K. Tsytsulina pers. comm. 2008).

In China, it is listed as Data Deficient (DD) (Jiang et al. 2016). It is locally protected as a rare species in three Russian regions: in Sakhalin and Khabarovsk regions as rare, and in Primoriye territory as endangered.
