Japan’s Ambitious Push to Lead the Next Era of Artificial Intelligence
Japan is making significant strides in the field of artificial intelligence (AI), with Prime Minister Sanae Takaichi at the helm of the country’s AI push. The government has introduced one of the world’s most ambitious regulatory and innovation agendas, aiming to make Japan a catalyst for economic revival. According to independent analyses, AI could raise Japan’s GDP by as much as 16 percent.
The country’s AI efforts have attracted the attention of major companies such as OpenAI and Anthropic, which have established offices in Tokyo. These companies are working closely with Japanese regulators to develop responsible AI practices, making Japan a strategic co-development hub for AI innovation.
Adoption of AI in Japanese Industry
Japanese companies such as Daikin, Toyota Connected, and Rakuten have adopted AI-powered tools like ChatGPT to enhance data analysis, automate workflows, and build custom assistants tailored to Japan’s business culture. Claude, a model developed by Anthropic, has been fully localized for Japanese users, with adjustments for cultural nuance, linguistic complexity, and local compliance rules. Panasonic, NRI, and Rakuten have also expanded their use of Claude for strategy, creative ideation, and secure enterprise deployments.
The Japanese government has passed the AI Promotion Act, a law that frames AI as a national priority requiring structured oversight and rapid adoption. The AI Strategic Headquarters, led by Prime Minister Sanae Takaichi, is responsible for knitting together domestic regulation, international partnerships, workforce initiatives, and sovereign digital infrastructure to ensure AI becomes a catalyst for economic revival.
Japanese LLMs Challenge Global Models
Most large language models are trained primarily on English text and struggle to serve non-English markets at scale. This gap has opened space for language-specific models designed for local accuracy and privacy. One of the most prominent is Tsuzumi 2, released by Japanese telecom giant NTT Inc. Tsuzumi 2 is far more efficient than its Western counterparts, running inference on a single GPU rather than dozens, and performs on par with—and sometimes better than—models several times its size, including GPT-5 and Claude 3.5, for Japanese-language reasoning.
According to Jan Wupperman, senior vice president of service assurance, data, and AI at NTT, “Frontier AI companies will never provide deeply localized, private Japanese-language models as part of their global roadmap. Tsuzumi 2 fills that gap.” The model is multimodal, able to process text, images, and voice in one workflow, and is designed to create small, task-optimized models trained across generic knowledge, industry knowledge, and client-specific knowledge.
Merging Quantum Computing with AI
The next bottleneck for global AI growth is raw computing power. Data centers are straining electrical grids, GPU wait times have stretched to months, and silicon-based chips are hitting physical limits. Japan believes the solution lies in merging quantum computing with AI. Together with OptQC, NTT is developing optical quantum systems that operate at room temperature, thereby avoiding the massive cooling systems required by traditional quantum machines.
These systems aim to accelerate molecular simulation, climate modeling, high-dimensional optimization, and AI training tasks that remain out of reach for classical machines. According to Wupperman, “Once quantum computing capacity reaches maturity, training an AI model will look entirely different. Instead of incremental improvements, this could shrink the training cycle of complex models from months to hours.” In the near term, AI will continue to advance faster than quantum, but over the next five to ten years, that relationship is expected to flip, with quantum becoming a force multiplier for AI—and AI helping accelerate quantum hardware design in return.
