Japan Cancer Vaccines Market Report Highlights:

• The Japan cancer vaccines market, by type, is segmented into prevention vaccines, treatment vaccines, and oncolytic viruses. The preventive vaccines dominated the market share in 2024. These vaccines aim to prevent cancers associated with viral infections, such as the human papillomavirus (HPV) vaccine, which reduces the risk of cervical cancer.
• Based on indication, the market is segmented into prostate, cervical, and others. The cervical cancer segment dominated the Japan cancer vaccines market share in 2024. This prominence is attributed to the high prevalence of human papillomavirus (HPV) infections, which are strongly linked to cervical cancer development.
• The market, by patient type, is segmented into pediatric and adult. The adult segment held a larger share of the Japan cancer vaccines market revenue in 2024 as cancer prevalence is higher in older populations. This prominence is also primarily attributed to the increasing incidence of human papillomavirus (HPV) infections among adults, which has created the demand for preventive vaccines targeting HPV-related cancers. However, pediatric cancer vaccines are gradually expanding with growing research into immunotherapies for childhood cancers.
• The market features several active companies contributing to advancements in oncology. A few notable players include Aduro BioTech, Inc.; Astellas Pharma, Inc.; Bristol-Myers Squibb; Tella, Inc.; Oncolys BioPharma Inc.; CYTLIMIC; Takeda Pharmaceutical Company Limited; Takara Bio; Daiichi Sankyo Company Limited; Merck & Co., Inc.; Moderna, Inc.; Chugai Pharmaceutical Co., Ltd.; Otsuka Holdings Co., Ltd.; Eisai Co., Ltd.; and Shionogi & Co., Ltd.
