The Japanese government and Prime Minister Sanae Takaichi unveiled a 370 trillion yen (about 2.3 trillion USD) investment plan on June 24 aimed at boosting AI, semiconductors, and 15 other strategic sectors through fiscal 2040/2041 [1, 2, 3].
The plan allocates 101.6 trillion yen specifically to AI and semiconductor development, with about 68 trillion yen dedicated to revitalizing the semiconductor industry and increasing domestic chip production [1, 2, 3, 4, 5]. Takaichi said, "We will cut off the trend of insufficient future investment" to recover Japan's global competitive edge [2].
Investment targets 17 key fields, including quantum computing, space, shipbuilding, key minerals, energy, and national defense [1, 2, 6, 4]. The government expects large economic ripple effects by 2040, projecting 443 trillion yen in returns from semiconductor investments and significant spillovers from physical AI (144 trillion yen) and vertical AI (222 trillion yen) [1, 5, 7].
Funding will come from public and private sectors, with government contributions expected to remain below half provided inflation holds near 2% [1, 2, 7]. The Japan Growth Strategy Headquarters formed in November 2025 will oversee execution [2, 4].
TSMC's new semiconductor plant in Kumamoto, opened earlier this year, marks an important step in Japan's tech ambitions [8]. Challenges include securing sustained financing, overcoming talent shortages, and maintaining political support over 15 years [9].
Harumi Taguchi, chief economist at S&P Global Market Intelligence, noted, "To my knowledge, this is the first time a growth plan spanning such a long time has been proposed; I have not heard of similar plans in other countries" [1].
The investment framework will be incorporated into the 2027 government budget and aligned with Japan’s broader fiscal and growth strategies [2, 4]. The target completion year is fiscal 2040/2041, aiming to restore Japan’s confidence and competitiveness in key high-tech industries [1, 6, 10].
