Core Event – New White Paper and Policy Shifts
On August 5, 2026, Japan’s Ministry of Defense released the 600-page “Defense of Japan 2026” white paper. It outlines plans to raise defence spending to about 2 % of GDP, a target originally set for 2027 but already met ahead of schedule, and to acquire long-range strike capabilities, including Tomahawk-type cruise missiles with an upgraded 1,000-kilometre range. The paper also stresses the need for a stronger domestic defence industry to support economic growth.
Background & Context
Japan renounced the right to maintain a military under Article 9 of its post-war constitution, yet created the Self-Defense Forces (SDF) in 1954. Since the early 2010s the SDF has undergone incremental upgrades. In 2022, amid Russia’s invasion of Ukraine, Prime Minister Fumio Kishida called for a “fundamental enhancement” of defence capabilities, prompting a series of budget increases and the acquisition of long-range missiles.
Data & Statistics
- Defence spending is on track to reach 2 % of GDP by 2027, a level already achieved ahead of schedule.
- The 2025 budget rose 9.7 % to $62.2 billion, the highest since 1958.
- Japanese land-based Type 25 anti-ship missiles now have a 1,000-km range, exceeding territorial defence needs.
- Chinese aircraft sorties around Taiwan increased to ?3,700 last year, up from ?970 in 2021; naval sorties rose to ?2,600.
Criticism & Opposition
- Kim Yo Jong, sister of North Korean leader Kim Jong Un, labeled Japan a “war-criminal state” accelerating its transformation into a “military state,” and warned that the DPRK will adopt “additional military options” in response.
- Makoto Ito, director of the Japan Institute of Constitutional Law, warned that Japan’s security environment would improve only if it remained committed to diplomatic stances that reassure neighbours, noting a deviation from the pacifist constitution.
- Kumiko Haba, distinguished professor at Josai International University, described the administration of Prime Minister Sanae Takaichi as moving toward a “government prepared to wage war,” citing the deployment of long-range missiles and the lifting of export restrictions on lethal weapons.
Verbatim Quotes
- “Japan legally does not have a military; it has a Self-Defense Force,” — Jeffrey Hornung, a senior political scientist at RAND
- “Japan's latest defense white paper is filled with false narratives, extensively exaggerates a 'regional security crisis' and hypes the so-called 'China threat,'” — Chen, defense ministry spokesman
What's Next – Future Milestones
Japan’s defence policy targets a 2 % of GDP spending level by 2027 and plans to continue expanding long-range strike capabilities and domestic defence-industry investment. The Ministry of Defence will publish annual updates in subsequent white papers, outlining further procurement and strategic cooperation with allies.
