Japan unveils a 370 trillion yen public-private growth plan through fiscal 2040 to drive growth across 17 strategic sectors and 62 products and technologies, with 28 priority items including semiconductors and artificial intelligence selected for focused investment.

The plan targets key areas such as data centers, AI, and critical minerals, and emphasizes mobilizing both public funding and private capital to build domestic capacity.

Analysts caution that true autonomy won’t come from mining alone; refining and processing capacity are essential to reduce dependence on China.

Observers say the success of the program will hinge on commissioning megawatts of capacity and securing binding supply agreements, not just headline investment totals.

Strategically sensitive dependencies include rare earth magnets, gallium, and germanium, with copper still dominating the overall scale of AI data-center mineral demand.

Market participants expect domestic investment upsurges in semiconductors, AI, and related sectors to benefit equipment suppliers, materials providers, and data center operators, even as implementation details are refined.

Prime Minister Sanae Takaichi underscored that large-scale, strategic investment support is necessary to establish a domestic semiconductor supply chain.

The strategy concentrates resources on priority items to attract private investment, with ongoing discussions about funding sources and private-sector cost-sharing as the plan progresses.

Priority items are split into current revenue sources (semiconductors, vertical AI, data centers, dual-use tech, pharmaceuticals and regenerative medicine, innovative medical devices, games and anime) and future growth drivers (Physical AI, autonomous driving, all-optical networks, next-gen communications, quantum computing, next-gen solar cells, plant factories, land-based aquaculture, and critical minerals for economic security).

Context includes geopolitical considerations affecting Western supply chains, such as critical minerals, rare earths, and export controls.

An implementation plan is to be formulated by year-end, designating the next five years as an intensive investment period to accelerate deployment.

Japan also plans a 32.7 trillion yen allocation through 2035 to bolster cloud infrastructure, data centers, and storage batteries to reduce external dependencies.
