SoftBank Group's mobile unit will convert part of its Osaka factory into one of Japan's largest battery production lines to power its own AI data centers.

The Japanese conglomerate aims to manufacture large-scale batteries at the converted facility, addressing growing power demands from its expanding AI infrastructure. The move represents SoftBank's effort to secure energy supply for its data center operations as artificial intelligence workloads intensify globally. The Osaka factory transformation aligns with broader industry trends of tech companies controlling their supply chains. Battery production in-house could reduce costs and dependencies on external suppliers, critical factors as AI data centers consume substantial amounts of electricity. SoftBank has positioned itself as a major AI investor and infrastructure builder through Vision Fund investments and partnerships. This battery initiative signals the company's commitment to vertical integration in the AI ecosystem. Details on production capacity, timeline, and investment amounts were not disclosed. The project reflects Japan's broader push to strengthen its position in AI hardware manufacturing amid global competition from the U.S. and China.
