Kusama graduated from the Faculty of Pharmaceutical Sciences of the University of Tokyo in 1997 and completed a master's degree in pharmaceutical sciences at the university in 1999. Her academic training led to work spanning clinical pharmacy, pharmacokinetics, pharmaceutical regulatory science, pharmacy education, and pharmacoepidemiology.
Kusama began her professional career in 1999 in the Department of Pharmacy at the University of Tokyo Hospital, where she worked as an assistant through 2004. Her early work included hospital pharmaceutical care, clinical pharmacy education, adverse-drug-reaction monitoring, and pharmacokinetic research. From 2005 she was associated with the University of Tokyo Graduate School of Pharmaceutical Sciences, where she served as an assistant professor in clinical pharmacokinetics and regulatory science. Her research examined pharmaceutical regulation in Japan, drug safety, clinical development, regulatory review, drug lag, pharmacokinetic variability, pharmacy education, and the development and use of hospital formularies. By 2016 she had moved to the Japan Agency for Medical Research and Development, where she worked in pharmaceutical research and later in the Division of Neurological, Psychiatric and Brain Research within the Department of Research Promotion. Her published work and professional activities include studies of drug clearance pathways, pharmacogenetic influences on pharmacokinetics, adverse-drug-reaction assessment, Japanese clinical development and regulatory policy, health literacy, pharmacy-based disease management, and validation of diagnosis codes in Japanese health-care data.
Conducted research in pharmacy education, pharmacoepidemiology, pharmaceutical regulation, clinical pharmacokinetics, drug safety, and drug policy.
Contributed to research on hospital formulary development, pharmacy-based disease management, clinical pharmacy education, and the validation of health-care diagnosis codes.
