Japan’s AI journey spans decades, from early machine translation and the 1980s Fifth Generation Computer Project to today’s generative AI startups. Despite less global visibility, Japan has steadily advanced with a focus on language, logic, and practical applications. Companies like Sakana AI, Preferred Networks, ABEJA, and Jitera are leading efforts in foundation models, robotics, business solutions, and low-code platforms. Challenges include limited Japanese training data, but this also creates opportunities for specialization. Backed by partnerships with corporations, universities, and global investors, Japan’s AI ecosystem is growing and positioning itself as a unique, collaborative force in the global AI landscape.
