In recent years, emerging infectious diseases have become a worldwide concern. Number of cases of Japanese spotted fever, and severe fever with thrombocytopenia syndrome (SFTS) transmitted by ticks is increasing in Japan. The authors collected ticks around Yokkaichi University (Mie Prefecture, Japan) to discuss their infectious risks. Ticks were collected sixteen times during February and October 2020, among a 930 meter trail in a bamboo forest behind the university studio facility. In total, thirty ticks of five tick species from two genera were identified. The most frequently collected species were Haemaphysalis flava, fifteen individuals. Number of confirmed cases of spotted fever and SFTS are larger in south Mie Prefecture, and range expansion of wildlife such as Japanese sika deer (Cervus nippon) is thought to be one factor. Since sika deer had already been sighted around Yokkaichi University, attention is required.
