The purpose of this study is to investigate the effect of transboundary transport from the Asian continent on the PM2.5 concentration in the Kanto metropolitan area in Japan and also to investigate the relationship between PM2.5 concentration and meteorological conditions. Daily PM2.5 concentrations exceeded the environmental quality standard in Japan for 9 days in 2014, and simultaneously air mass had come from Asian continent in most cases. Such high PM2.5 events were likely to occur when secondary particle formation was very active in the neighborhood area as well as the transboundary transport from the Asian continent to the Kanto area was also active.
