Japan has announced a $550 billion investment package aimed at enhancing energy infrastructure in the United States. The initiative involves around 20 companies from both countries, including major players like SoftBank, Westinghouse, and Hitachi, with projects valued at approximately $400 billion. The investment will be supported by equity, loans, and guarantees from Japanese state-owned institutions, featuring a profit-sharing model that transitions to 90% US ownership after Japan recoups its investment. Key projects under this package include the development of modular reactors, spearheaded by Westinghouse and Hitachi. Initial projects are expected to be identified by late 2025, marking a significant step in US-Japan energy collaboration.
