# Japan weighs a ¥60 trillion five-year defense plan, below the ¥70 trillion to ¥80 trillion its Defense Ministry says it needs

The figure would be about 40% above the current ¥43 trillion plan, and Kyodo reports that a corporate tax increase is under discussion to help pay for it.

Japan's government is considering setting its next five-year defense plan at [¥60 trillion](https://www.japantimes.co.jp/news/2026/11/14/japan/politics/defense-spending-defense-ministry-finance-ministry/), the Japan Times reported. The Defense Ministry estimates that the necessary spending over the period will total ¥70 trillion to ¥80 trillion. The gap between the two numbers reflects the dispute between the Defense Ministry and the Finance Ministry. The current plan, covering fiscal 2023 to 2027, [set the required level at about ¥43 trillion](https://www.mod.go.jp/j/press/wp/wp2025/html/n220304000.html).

Funding is the political problem. Kyodo, in a report carried by the Kumamoto Nichinichi Shimbun, said [an additional corporate tax increase has been floated](https://kumanichi.com/articles/2047661) inside the government and that annual defense spending is likely to exceed ¥10 trillion. The next plan, for fiscal 2027 to 2031, is expected to center on large purchases of drones and on stockpiles of munitions and missiles for a prolonged conflict.

Domestic critics question the money. Shimbun Akahata, the Japanese Communist Party newspaper, wrote that an earlier draft would make the plan [about 1.8 times the current one](https://www.jcp.or.jp/akahata/aik26/2026-11-04/2026110401_03_0.php) and said the government of Prime Minister Sanae Takaichi cannot show how it would pay for it. The figures may change during year-end budget work and the planned revision of Japan's three security documents.

Tokyo presents the increase as a response to China's military growth and to doubts about how much it can rely on US commitments. Beijing has repeatedly said Japan's military buildup threatens regional stability.

## What this means

Japan is moving from about ¥8.6 trillion a year to more than ¥10 trillion a year in defense spending at a time when Japanese government bond yields are under pressure from rising global rates. Higher spending funded partly by debt adds bond supply, and a corporate tax increase cuts into earnings for Japanese companies. Domestic defense contractors, shipbuilders and drone and munitions makers gain directly. The market expected the defense budget to keep growing, but not that the government would consider a figure close to 40% above the current plan, or a new corporate tax. Germany's 2025 decision to exempt defense from its debt brake is a recent precedent: defense stocks rose and Bund yields moved higher. The likelier outcome by the end of December is a plan near ¥60 trillion with partial tax funding, followed by pressure from the Defense Ministry for supplementary budgets. This depends on the ruling coalition keeping its majority on the tax measure. It would be wrong if Tokyo settles well below ¥60 trillion, which would mean fiscal limits are winning over security demands.

## What to watch

- Watch the final figure in the year-end security document revision. Whether it lands at ¥60 trillion or closer to ¥70 trillion will show which ministry won.
- Watch whether a corporate tax increase appears in the fiscal 2027 tax reform outline. Its inclusion would show the government chose taxes over additional bond issuance.
- Watch China's official response once the figure is set. Countermeasures such as export restrictions or naval patrols would show the arms race affecting trade.
