The genetic characterization of archival specimens is important for evaluating the evolutionary processes of noroviruses. Complete viral genome sequences, GVIII.1[GII.P28] and GIX.1[GII.P15], were determined from two archival specimens collected in Tokyo, Japan, in 1986 and 1995. In addition, complete VP1 and partial RdRp sequences of four samples collected between 1975 and 1983 were determined. Two viruses were classified as GI.5[P5] and GI.9[P9]; however, the viruses from the other two samples could not be assigned to any known genotypes using norovirus typing tools and phylogenetic analysis, suggesting that they might be untypable genotypes. Further evolutionary analysis of these viruses is warranted.
