SoftBank Bets Big on AI Power: Giant Battery Plant Planned
24 Apr
Summary
- SoftBank plans a multi-gigawatt hour battery plant in Osaka.
- The facility will initially power SoftBank's AI data centers.
- Production is expected to start within the next five years.

SoftBank Corp. is embarking on an ambitious plan to construct one of Japan's largest battery production facilities in Osaka, aiming for a total capacity of several gigawatt hours. This new venture is strategically designed to support the company's burgeoning AI data center infrastructure.
The facility, to be located in Sakai city, is targeted to begin production within the next five years. Executives are exploring advanced cell technologies, potentially moving beyond standard lithium iron phosphate batteries to compete more effectively with global players.
Initially, the batteries produced will serve SoftBank's internal AI data center needs. Subsequently, the company plans to extend this battery support to other Japanese enterprises, fostering greater national manufacturing self-reliance.
This initiative aligns with SoftBank Group's broader vision led by Masayoshi Son to be a significant force in the global AI race, investing heavily in data centers and AI-related technologies. The project is expected to be formally announced next month by SoftBank Corp. CEO Junichi Miyakawa as part of a new five-year business plan.
