Japan's generative AI landscape is taking a unique path, focusing on specialized "bonsai AI" models in fields like medicine and finance. This approach addresses the challenge of limited Japanese language data. However, Japan faces hurdles in AI infrastructure, including NVIDIA's GPU market dominance and a shortage of AI specialists. The Japan Fair Trade Commission is monitoring the market to prevent monopolization and ensure fair competition. Despite these challenges, Japan aims to create an efficient, equitable, and human-centered AI society. This overview explores Japan's AI development strategy, its distinctive features, and the obstacles it faces. It raises questions about the global impact of Japanese AI and how humanity can best coexist with these advancing technologies.
