Japan's Prime Minister Takaichi Sanae is poised to advance a revised security doctrine following the Liberal Democratic Party's (LDP) landslide victory in the February 2026 election, securing 316 seats in the House of Representatives. Her agenda includes deepening the Free and Open Indo-Pacific strategy and expanding Japan's defense capabilities, potentially by revising constraints such as the Three Non-Nuclear Principles and limits on arms exports.
However, the expansion of defense spending faces significant hurdles due to Japan's severe fiscal constraints and substantial long-term debt. Takaichi's administration is also prioritizing economic policy, pledging aggressive fiscal spending to combat inflation and soaring living costs. This includes an economic stimulus package worth over 13.9 trillion yen, measures to abolish the provisional gasoline tax rate, and an increase in the income tax exemption threshold to 1.6 million yen.
Takaichi's economic strategy emphasizes "responsible and proactive fiscal policy," aiming to raise incomes and boost business profits without resorting to higher tax rates. The focus will be on reducing the government debt-to-GDP ratio rather than pursuing a primary balance surplus. A Growth Strategy Council will be established to guide innovation and industrial revitalization efforts. The U.S. President Donald Trump's request for Japan to send naval assets to the Strait of Hormuz is also a key consideration for her security policy.
