Asama virus (ASAV) is a single-stranded, enveloped, segmented negative-sense RNA hantavirus.Arai S, Ohdachi SD, Asakawa M, Kang HJ, Mocz G, Arikawa J, Okabe N, Yanagihara R.Molecular phylogeny of a newfound hantavirus in the Japanese shrew mole (Urotrichus talpoides).Proc Natl Acad Sci U S A.2008 Oct 21;105(42):16296–301. The hantavirus was isolated in Japan from Japanese shrew mole. Hantaviruses harbored by shrews are genetically closer to ASAV than to hantaviruses harbored by rodents. Host-switching may be evident in the future due to the viruses closeness to soricine shrew-borne hantaviruses. The detection of the ASAV was the first hantavirus found to be hosted by members of the family Talpidae, which includes shrew moles.{{Cite book|url=https://books.google.com/books?id=wHOWj8i2FcUC&dq=asama+virus&pg=PA199|title=New Frontiers of Molecular Epidemiology of Infectious Diseases|last1=Morand|first1=Serge|last2=Beaudeau|first2=François|last3=Cabaret|first3=Jacques|date=2011-09-08|publisher=Springer Science & Business Media|isbn=9789400721142|language=en}} Thoughts on hantavirus evolutionary history has expanded due to the discovery of ASAV.
