Plum pox virus (PPV) was detected in the orchards in Higashi-kurume city, Tokyo in 2014. Survey took place at the two orchards in Higashi-kurume 2 times per year from 2014 to 2017. PPV infected trees were detected every year in two orchards. The total number of infected tree was 21(Orchard No.1: 8, Orchard No.2 :13). The phylogenetic analysis of the 20 isolates from main branches of 13 trees using complete PPV genome sequences revealed that all the isolates of Higashi-kurume were closely related to isolate Ou 7, which was isolated from the Orchard of Ome city. Having compared the complete sequences of all isolates, the isolates of the same orchard showed a more closer relationship than the isolates of the other orchard. Farther, the same mutation was found in neighboring PPV infected trees detected in 2015, 2016 and 2017. It seems that PPV was introduced independently into two orchards before 2014, then spread to neighboring trees by aphids respectively.
