Anthropic to Open First Asia Hub in Tokyo Fall 2025 - Targeting Japanese Enterprise AI Demand

AI development company Anthropic has revealed it will establish its first Asian office in Tokyo in fall 2025. Known for developing the conversational AI “Claude,” the company has garnered attention as a rival to OpenAI’s ChatGPT. This Tokyo office opening aims to capture AI demand from Japanese companies facing labor shortages¹.

Anthropic is an AI startup founded in 2021 by former OpenAI executives and has received $8 billion in investment from Amazon and massive investment from Google. While the company already has offices in San Francisco headquarters, London, Seattle, Dublin, and Zurich, this marks its first expansion into Asia².

Tokyo Office Overview and Strategy

The Tokyo office is planned to focus on B2B (business-to-business) sales activities and customer support. Previously, the company has acquired Japanese customers through Amazon and Google, but with this office establishment, it will begin full-scale independent business operations in Japan¹.

Expectations for the Japanese Market

The background to Anthropic’s choice of Japan as its first Asian hub lies in the promising nature of Japan’s AI services market. The company particularly focuses on the demand for labor-saving technologies among Japanese companies struggling with labor shortages. Indeed, Japanese companies’ formal adoption rate of generative AI is at a lower level compared to the United States, China, and the United Kingdom, suggesting significant room for growth¹.

Anthropic has already begun collaborations with Japanese companies such as Panasonic and Rakuten Group, and aims for further market development based on these achievements. The Tokyo office opening is expected to enable closer customer support than ever before.

Enhanced Japanese Language Support for Claude

One important role of the Tokyo base is improving Claude AI’s Japanese user experience. Currently, Claude supports multiple languages including Japanese, but there is still room for improvement in its accuracy.

Current Japanese Language Support Status

The Claude 3 model supports major languages including Spanish, Japanese, French, Portuguese, and German. In the MGSM benchmark, it has recorded scores of over 90% in French, Russian, Chinese (Simplified), Spanish, Bengali, Thai, German, and Japanese³.

However, Japanese training data is still limited compared to European languages, and challenges remain in achieving complete Japanese language capabilities. While basic conversation and translation are possible, further improvements are needed for more advanced business applications.

Intensifying Competition in Japan’s AI Market

Anthropic’s Tokyo expansion means further intensification of competition in Japan’s AI market. OpenAI established a Japanese subsidiary in April 2024, strengthening its presence in the Japanese market. Competition between both companies will create more diverse AI solution options for Japanese enterprises.

Enterprise Service Development

Anthropic plans to propose Claude utilization in various corporate activities including product development, marketing, and customer support. Particularly, it is expected to provide AI-powered business efficiency solutions to address labor shortage challenges faced by Japanese companies.

The company has already begun building relationships with Japan’s startup and business communities, hosting the “Tokyo AI Founder Salon” jointly with AWS and Globis Capital in Tokyo. Executives including Kate Jensen (Sales Director) and Jason Kim (Researcher) have visited Japan, steadily preparing for full-scale market entry.

Recruitment Activities and Future Development

Anthropic has already begun talent recruitment for the Tokyo office, rushing to build its local structure. Strengthening Japanese language support and securing talent capable of addressing Japanese companies’ unique needs are important challenges¹.

Acceleration of Global Expansion

The company is accelerating international expansion through recent funding. From March to May 2025 alone, annual revenue increased by $1 billion, reaching $3 billion annually. With this substantial financial backing, it is advancing next-generation AI system development, computational capacity expansion, mechanism interpretability and alignment research deepening, and international expansion acceleration².

The Tokyo office opening is an important part of this international expansion strategy and represents the first step in establishing the company’s presence in the Asia-Pacific region.

Anthropic’s strategic choice of Tokyo as its first Asian hub reflects both Japan’s untapped AI potential and unique market needs. With Japanese companies’ formal AI adoption rates lagging behind the US, China, and UK despite facing severe labor shortages, the opportunity for AI-driven transformation is substantial. The company’s focus on B2B solutions and enhanced Japanese language support positions it to address these specific challenges directly.

The timing is particularly significant as Anthropic enters direct competition with OpenAI’s established Japanese presence. This rivalry, combined with Anthropic’s $8 billion backing from Amazon and Google, promises to accelerate innovation and create more sophisticated AI solutions tailored to Japanese business culture. As fall 2025 approaches, the success of Anthropic’s localization efforts - from language capabilities to understanding Japanese corporate needs - will determine whether it can convert Japan’s AI adoption gap into a competitive advantage.
