H.M. and S.A. were involved in the nationwide external quality assessment of SARS-CoV-2 nucleic acid tests, a project commissioned by the Ministry of Health, Labour and Welfare of Japan. S.A. contributed to studies on SARS-CoV-2 PCR tests developed by DENSO Corp. and KYORIN Pharm. Co., Ltd. that were financially supported by the Japan Agency for Medical Research and Development. R.K. and K.O. rendered laboratory service for athletes and team officials during the Tokyo 2020 Games as a commission project by the Tokyo Organizing Committee of the Olympic and Paralympic Games.
