Microsoft Plans $10B Japan AI Push with SoftBank
Microsoft said it will invest $10 billion in Japan between 2026 and 2029 to build AI infrastructure, strengthen cybersecurity and train 1 million engineers and developers by 2030. The company has begun discussions with Japanese cloud provider Sakura Internet and SoftBank to develop AI computing resources — including GPUs located in Japan — and announced partnerships with other major Japanese IT firms such as NTT Data, NEC, Fujitsu and Hitachi. The move, announced during Microsoft Vice Chair and President Brad Smith’s visit to Tokyo where he met Prime Minister Sanae Takaichi, aims to enable data processing inside Japan and support development of domestic large language models. Sakura Internet shares jumped about 20% after the announcement; SoftBank Group and SoftBank Corp. saw smaller gains.
Major cloud provider (Microsoft) committing $10B and partnering with domestic firms to build AI infrastructure and talent in Japan will materially affect cloud capacity, data residency, LLM development and regional competitive dynamics.
