Japan invests additional $4 billion in Rapidus to compete in the global AI chip manufacturing market alongside tech giants.

Japan approved ¥631.5 billion ($4 billion) in new subsidies for Rapidus Corp. to accelerate its AI chip production capabilities

The funding is designated to support Rapidus' work with major client Fujitsu Ltd., a key partner in launching Japan's domestic chip initiative

Total government investment in the startup now reaches ¥2.6 trillion, reflecting Japan's commitment despite the project being viewed as a risky long-term bet

The initiative aims to reduce Japan's dependence on foreign AI chip suppliers and establish domestic competitiveness in the high-stakes semiconductor industry
