Since around November 2020, we have been conducting research studies with Kyoto University, Kochi University, and others, and in July 2021, we received approval for the “Shiga New Industry Creation Challenge Plan Approval Project” and established test method. In the future, we aim to establish a cooperative framework with the national and local governments in the field of sewage epidemiology and provide monitoring services that combine sewage epidemiological surveys with human testing.
