Fly outbreaks including blow flies in the following year of the northern Japan great tsunami disaster were investigated around rubble mounts, abandoned school and fish processing plants in the Tsunami affected area. In the late of April, 2012, synanthropic flies such as house flies, Musca domestica, blow flies including Phormia regina, Calliphora nigribarbis and Sarcophagic flies were quite a few in the affected areas by adhesive fly trap collection. Those flies were not increased in the end of May by fly trap collection and insect net sweeping, and also a few in July collecting by the net. Disappearance of the synanthropic flies seem to have brought by removing rotten fish, dried up rotten fish or insecticide spraying in the previous year. Some lesser house flies, Fannia canicularis were collected in abandoned factories and an abandoned school in May and July. However, the lesser fly problem would not be occur due to far distances to human residences from hovering space. We concluded that fly problem would not be serious in the following year of the tsunami affected area.
