Japan’s Cabinet Office released materials on June 24 outlining a public-private investment roadmap that estimates cumulative investment of more than ¥370 trillion through fiscal 2040 across 62 products and technologies in 17 strategic fields under Prime Minister Sanae Takaichi’s growth strategy.
The estimate is presented as a provisional total that excludes items for which investment cannot yet be specified through fiscal 2040 and may be revised as assumptions are refined or additional items are added. The government said the figure is separate from its earlier target of ¥200 trillion in annual domestic investment in fiscal 2040 because the new total aggregates annual investment flows over roughly 15 years for the selected products and technologies.
The largest disclosed categories include ¥68.0 trillion for semiconductors, ¥23.1 trillion for vertical AI, ¥10.5 trillion for physical AI including AI robots, ¥32.7 trillion through fiscal 2035 for cloud, data centers and storage batteries, ¥20.5 trillion for next-generation wireless, ¥12.8 trillion for biomanufacturing, ¥23.4 trillion for first- or best-in-class drug products, ¥20.8 trillion for biopharmaceuticals and regenerative medicine, and ¥24.5 trillion through fiscal 2033 for games.
Other areas listed in the documents include quantum computing, next-generation solar cells, offshore wind, advanced nuclear reactors, fusion energy, autonomous driving, satellites, lunar and low-earth-orbit technologies, shipbuilding, materials, food technology, port logistics and disaster prevention. The Cabinet Office said the estimates were compiled through working-group discussions, ministry hearings with major companies and organizations, and market-based assumptions where company plans are not clear, and that the roadmap will be updated through the budget process and subsequent reviews.
