VISION IV is a technology company focused on leveraging diamond materials to advance quantum sensing, radiation detection, and semiconductor devices. Its core offerings already include a second-generation diamond anvil and B-doped diamond substrates, and the firm has built a complete evaluation cycle for diamond-based radiation sensors. Backed by approximately ¥300 million (≈US$2 million) in seed capital, the company has expanded research facilities, introduced new equipment, and increased laboratory space to accelerate R&D. VISION IV collaborates with the University of Tokyo and Hiroshima University on crystal quality, large-scale equipment deployment, and AI-driven defect inspection. Near-term priorities center on moving prototypes to full commercialization, securing additional joint-research grants, and deepening partnerships and purchase agreements with major corporations. Looking ahead, management intends to raise a Series A round, strengthen its team structure, and invest in capabilities that enable larger-scale, high-purity, and mass production of diamond devices.
