The Redmond-based technology giant disclosed plans to deploy approximately 1.6 trillion yen — equivalent to roughly $10 billion — throughout Japan from 2026 to 2029. This capital allocation will target AI infrastructure development, enhanced cybersecurity collaboration, and an educational initiative aimed at training 1 million engineers and developers within the next six years.
Brad Smith, Vice Chair and President of Microsoft, revealed these plans during a diplomatic visit to Tokyo, where he held discussions with Japanese Prime Minister Sanae Takaichi.
Sakura Internet, which operates an extensive network of data centers throughout Japan, will collaborate with SoftBank to deliver AI computational resources as part of this strategic alliance. The partnership specifically includes providing graphics processing units that remain physically situated within Japanese borders.
This infrastructure arrangement enables corporations and government entities to maintain data sovereignty by processing sensitive information domestically, while simultaneously leveraging Microsoft Azure cloud services.
Additionally, SoftBank and Microsoft Japan are engaged in ongoing negotiations to develop an integrated solution allowing Azure users to access SoftBank’s AI computing infrastructure seamlessly.
Market response saw SoftBank Group finish Friday’s session up 0.22%, while SoftBank Corp. gained 1.02%.
Japan’s AI Opportunity
Microsoft highlighted Japan’s robust embrace of AI technology as a key factor driving this substantial investment. Data from Microsoft’s AI Diffusion Report indicates that approximately 20% of Japan’s working-age population currently utilizes generative AI tools, surpassing the global average of roughly 16%.
According to Smith, the expanding demand for cloud computing and AI capabilities across Japan justifies this investment, which also complements Prime Minister Takaichi’s strategic vision of leveraging cutting-edge technology to drive economic expansion and strengthen national security infrastructure.
Extended Collaboration Framework
In addition to Sakura Internet and SoftBank, Microsoft revealed partnerships with five additional prominent Japanese technology corporations to achieve its ambitious target of training 1 million AI professionals by 2030. This coalition includes industry leaders such as NTT Data Corp., NEC, Fujitsu, and Hitachi.
The collaborative framework will also facilitate the creation and advancement of indigenous large language models tailored for the Japanese market.
On the cybersecurity front, Microsoft’s cooperation with Japanese authorities will encompass intelligence sharing regarding cyber threats and coordinated crime prevention efforts.
Sakura Internet shares concluded Friday’s trading at 2,967.00 JPY, representing a gain of 500.00 JPY for the session.
