In this study, data provided by 10 tropospheric aircraft surveys over Japan in 2014 confirm the existence of a vast diversity of microbial species up to 3,000 m height, which can be dispersed above the planetary boundary layer over distances of up to 2,000 km, thanks to strong winds from an area covered with massive cereal croplands in Northeast (NE) Asia. Microbes attached to aerosols reveal the presence of diverse bacterial and fungal taxa, including potential human pathogens, originating from sewage, pesticides, or fertilizers. Over 266 different fungal and 305 bacterial genera appeared in the 10 aircraft transects. Actinobacteria, Bacillota, Proteobacteria, and Bacteroidetes phyla dominated the bacteria composition and, for fungi, Ascomycota prevailed over Basidiomycota. Among the pathogenic species identified, human pathogens include bacteria such as\n                    <jats:italic>Escherichia coli, Serratia marcescens, Prevotella melaninogenica, Staphylococcus epidermidis, Staphylococcus haemolyticus, Staphylococcus saprophyticus, Cutibacterium acnes, Clostridium difficile, Clostridium botulinum, Stenotrophomonas maltophilia, Shigella sonnei, Haemophillus parainfluenzae<\/jats:italic>\n                    and\n                    <jats:italic>Acinetobacter baumannii<\/jats:italic>\n                    and health-relevant fungi such as\n                    <jats:italic>Malassezia restricta<\/jats:italic>\n                    ,\n                    <jats:italic>Malassezia globosa<\/jats:italic>\n                    ,\n                    <jats:italic>Candida parapsilosis<\/jats:italic>\n                    and\n                    <jats:italic>Candida zeylanoides, Sarocladium kiliense, Cladosporium halotolerans,<\/jats:italic>\n                    and\n                    <jats:italic>Cladosporium herbarum<\/jats:italic>\n                    .
