GREE, a Japanese internet company, is actively involved in digital human, VTuber, and metaverse development through its dedicated research arm, GREE VR Studio Lab (now part of REALITY, Inc.). The company has invested in the creation and implementation of digital humans across XR, AR/VR, and AI technologies, particularly for entertainment, education, and advertising. GREE has hosted events such as the #VRSionUp! workshops and CCSE conferences, promoting research on human-like avatars, 3D makeup, and expressive control systems for VTubers. Its VR Studio Lab collaborates with academic and industry groups to push digital human realism and interactivity. GREE has also been highlighted in collaborations involving large-scale digital human projections, holograms, and real-time character interactions. Its broader ecosystem ties into social networking and gaming origins (e.g., mixi, GREE platform), now expanded to the development of immersive digital identity and AI-based content creation platforms.
