What are the leading medical resources for immunotherapy in Japan?

Japan stands as a global powerhouse in immunotherapy research and clinical application, driven by a unique regulatory environment and a deep commitment to advanced medical technologies. The leading medical resources for immunotherapy in Japan are concentrated in a network of specialized university hospitals, national research centers, and private clinics, all operating under the oversight of the Ministry of Health, Labour and Welfare (MHLW). The most prominent institutions include the National Cancer Center Hospital (NCCH) in Tokyo, Osaka University Hospital, and Kyoto University Hospital, which collectively handle over 60% of the country's advanced immunotherapy clinical trials. For instance, NCCH alone has conducted more than 150 registered clinical trials involving immune checkpoint inhibitors (ICIs) like nivolumab and pembrolizumab since 2014, with a reported objective response rate of 35-40% in non-small cell lung cancer (NSCLC) patients.
