About JBeam

J BEAM INC., established in 2014 and headquartered in Fukushima Prefecture, specializes in leveraging neutron beam technology to develop cutting-edge products in the medical and industrial sectors. The company aims to contribute to societal development and post-earthquake reconstruction through its innovative solutions. One of its core focuses is Boron Neutron Capture Therapy (BNCT), a promising radiation therapy for cancer treatment. BNCT has the potential to offer radical treatment options for cancer, which remains a leading cause of death in Japan. J BEAM is working on making BNCT more accessible by developing systems that can be installed in many hospitals, overcoming the current limitation of requiring large-scale facilities. The company's business model revolves around research and development, product innovation, and partnerships with medical institutions and industrial clients. Revenue is generated through the sale and licensing of its advanced neutron beam technology solutions.
