Japan plans $1.6b extra budget to support AI, chip industries

Japan plans to allocate about ¥252.5 billion (US$1.6 billion) in an extra budget to support AI and semiconductor development.

The amount is lower than last year’s ¥1.5 trillion (US$9.59 billion) supplementary budget, as the government shifts toward regular budget funding for these sectors.

Prime Minister Sanae Takaichi’s cabinet approved the proposal on November 28, and the measure now awaits parliamentary approval.

Japan has dedicated around ¥5.7 trillion (US$36.5 billion) to revive its semiconductor industry since launching a new strategy in 2021, backing projects involving Rapidus, TSMC’s Kumamoto foundries, and Micron’s Hiroshima facility.

The Ministry of Economy, Trade and Industry has also requested ¥100 billion for Nippon Export and Investment Insurance to bolster the government-backed insurer’s finances.

Additionally, ¥93.7 billion (US$599 million) has been proposed to help private firms secure rare earths and increase national reserves, part of Japan’s efforts to reduce reliance on China for key minerals.

🧠 Food for thought

Implications, context, and why it matters.

Japan’s shift to regular budgets signals a long-term chip plan and raises funding questions

  • Japan is moving chip support into the regular budget instead of relying on extra packages, which signals a lasting focus that could bring steadier multi-year backing for Rapidus plus TSMC’s Japan work.
  • The cut from ¥1.5 trillion in extra funds to ¥252.5 billion raises doubts about staying competitive while other countries pour larger subsidies into chip plants.
  • Officials have not released a split for the smaller sum across AI and chip sub‑priorities, which blurs who gains the most from a tighter pool.

Foreign rare earth firms can tap Japan’s ¥93.7 billion plan through Japan Organization for Metals and Energy Security (JOGMEC) ties and Nippon Export and Investment Insurance (NEXI) cover

  • JOGMEC’s memorandum of understanding with U.S.-based REAlloys, a rare earths‑focused company, sets a template. It combines tech transfer of Japanese separation plus magnet fabrication, structured offtake guarantees (agreements to buy future production) and licensing that Western producers could use to reach Japan 1.
  • The Lofdal partnership in Namibia, a heavy rare earth mining project, outlines a path where the agency can earn up to 50% ownership with options for a carried working interest, which targets dysprosium and terbium supply chains 2.
  • Expanded NEXI capacity would give battery materials firms and miners outside Japan government-backed export insurance to Japanese buyers, which lowers counterparty risk and can unlock project financing that commercial lenders will not provide alone.
