Analysis on the Trends and Multidimensional Implications of Japan's "Re-militarization"

摘要 (Abstract)

二战后，日本在美国庇护下长期奉行“和平宪法”与“专守防卫”原则。然而，近年来日本安保政策发生根本性转向，通过修订安保文件、突破军费上限、获取“反击能力”及放宽武器出口限制，加速向“正常国家”与军事大国转型。本文旨在剖析日本“再军事化”的深层动因、具体路径及其对亚太安全架构、地区军备竞赛及战后国际秩序的冲击与挑战。

After World War II, under the protection of the United States, Japan long adhered to its "Peace Constitution" and the principle of "exclusively defense-oriented policy" (Senshu Boei). However, recent years have witnessed a fundamental shift in Japan's security policy. By revising security documents, breaking through defense budget ceilings, acquiring "counterstrike capabilities," and easing restrictions on weapon exports, Japan is accelerating its transformation into a "normal state" and a major military power. This article analyzes the underlying drivers and specific pathways of Japan's "re-militarization," as well as its impacts and challenges to the Asia-Pacific security architecture, regional arms races, and the post-war international order.

一、 历史回溯与驱动逻辑：为何此时加速？

I. Historical Retrospection and Driving Logic: Why the Acceleration Now?

【中文】

日本当前的“再军事化”并非一日之功，而是其右翼政治势力长期夙愿与外部环境变化的叠加产物。

1. 战略目标：彻底摆脱“战败国”身份束缚，谋求政治大国与军事大国的匹配地位，修改和平宪法第九条是其终极政治目标。

2. 外部借口：俄乌冲突与朝鲜半岛局势被日方利用，同时借美国“印太战略”需求，以“中国威胁论”为主要叙事工具，为扩军备战制造合法性。

3. 同盟捆绑：日美同盟深度绑定，日本主动寻求成为美国亚太战略的“北方锚点”与“副警长”，通过承担更多进攻性职能换取美国对其修宪扩武的默许。

Japan's current "re-militarization" is not an overnight occurrence but the cumulative result of long-held aspirations of right-wing political forces combined with shifts in the external environment.

1. Strategic Objective: To completely shed the constraints of its "defeated nation" status, matching its political ambitions with military capabilities. Revising Article 9 of the Peace Constitution remains the ultimate political goal for conservative factions.

2. External Pretext: Utilizing the Russia-Ukraine conflict and tensions in the Korean Peninsula, coupled with alignment with the U.S. "Indo-Pacific Strategy," Tokyo has constructed a narrative centered on the "China threat theory" to legitimize military buildup.

3. Alliance Alignment: With the deepening integration of the Japan-U.S. alliance, Japan actively seeks to serve as the "Northern Anchor" and "Deputy Sheriff" for the U.S. regional strategy. By assuming more offensive roles, Japan secures American acquiescence for its constitutional revision and military expansion.

二、 核心表现：从“盾”到“矛”的质变

II. Core Manifestations: Qualitative Changes from "Shield" to "Spear"

【中文】

日本“再军事化”已从量变积累进入质变爆发期，主要体现为以下五大维度：

1. 防卫预算跃升：打破GDP占比1%的隐形红线，2026财年防卫预算突破9万亿日元，向占GDP 2%（北约标准）乃至更高比例迈进，连续多年创历史新高。

2. 战略文件重构：修订“安保三文件”（2022年版及后续修订），明确抛弃“专守防卫”底线，正式确立发展“反击能力”（对敌基地攻击能力），将防区概念扩展至“跨域/全球”。

3. 进攻性战力部署：

   • 远程打击：量产并部署射程超1000公里的改进型12式岸舰导弹、采购美制“战斧”巡航导弹，西南诸岛（如琉球、与那国岛）军事要塞化，剑指台海与东海。

   • 新兴领域：组建“宇宙作战团”、网络防卫力量，抢占天网电战高地。

4. 制度松绑：大幅修订《防卫装备转移三原则》，实质性解禁杀伤性武器出口，不仅向乌克兰、菲律宾等国提供军备支持，更试图激活国内军工复合体，向外输出影响力。

5. 指挥体制变革：探讨设立“联合作战司令部”（JJOC），旨在提升自卫队与美军协同效率，实现指挥权对等化，进一步摆脱“美主日从”的被动格局。

Japan's "re-militarization" has transitioned from quantitative accumulation to a phase of qualitative transformation, primarily manifesting in the following five dimensions:

1. Surge in Defense Budget: Breaking the unwritten cap of 1% of GDP, Japan's defense budget for FY2026 exceeded 9 trillion yen, advancing toward the NATO standard of 2% of GDP (and potentially higher), hitting record highs for consecutive years.

2. Restructuring of Strategic Documents: Revision of the "Three Security Documents" (2022 version and subsequent updates) explicitly abandoned the bottom line of the "exclusively defense-oriented policy" and formally established the development of "counterstrike capabilities" (enemy base attack capabilities), expanding the concept of defense perimeter to "cross-domain/global".

3. Deployment of Offensive Capabilities:

   • Long-range Strikes: Mass production and deployment of improved Type-12 anti-ship missiles (range >1,000km) and procurement of U.S. Tomahawk cruise missiles. The fortification of the Southwest Islands (e.g., Ryukyu, Yonaguni) directly targets scenarios in the Taiwan Strait and East China Sea.

   • Emerging Domains: Formation of "Space Operations Units" and Cyber Defense Forces to seize the high ground in space, cyber, and electromagnetic warfare.

4. Institutional Relaxation: Significant revision of the "Three Principles on Transfer of Defense Equipment," substantively lifting the ban on lethal weapon exports. Japan now provides military aid to countries like Ukraine and the Philippines and seeks to revitalize its domestic military-industrial complex to project influence outward.

5. Command Structure Reform: Discussions regarding the establishment of a "Joint Operations Command" (JJOC) aim to enhance JSDF-U.S. military interoperability and move toward parity in command authority, further shedding the passive "U.S.-led, Japan-supported" framework.

三、 多维影响：地区安全与战略平衡的重构

III. Multidimensional Implications: Reconstruction of Regional Security and Strategic Balance

【中文】

日本激进的“再军事化”进程对亚太乃至全球安全格局产生了深远的负面冲击：

1. 加剧安全困境与军备竞赛：日本的扩军行为直接刺激周边国家采取反制措施，导致东北亚陷入“安全困境”螺旋。特别是远程导弹部署与核共享讨论，加剧了核扩散风险与战略误判可能。

2. 冲击战后国际秩序：日本作为二战战败国，否定侵略历史、架空和平宪法的行为，挑战了《开罗宣言》《波茨坦公告》确立的战后秩序根基。若其突破“无核三原则”，将直接动摇国际核不扩散体系（NPT）。

3. 台海风险显著上升：日本政界频繁炒作“台湾有事即日本有事”，将西南诸岛作为介入台海的跳板，极大增加了中国在解决核心利益问题时面临的地缘阻力与冲突外溢风险。

4. 阵营对抗固化：日本积极构建“美日+”小多边机制（如日美菲、日美澳），拉拢北约入亚，推动亚太地区北约化与“新冷战”阵营对抗，削弱了东盟的中心地位。

【English】

Japan's radical "re-militarization" process has profound negative implications for the security landscape of the Asia-Pacific and beyond:

1. Exacerbating the Security Dilemma and Arms Race: Japan's military expansion directly prompts countermeasures from neighboring countries, trapping Northeast Asia in a spiral of the "security dilemma." Particularly, the deployment of long-range missiles and discussions on nuclear sharing heighten the risks of nuclear proliferation and strategic miscalculation.

2. Challenging the Post-War International Order: As a defeated power in WWII, Japan's denial of its history of aggression and the hollowing out of its Peace Constitution challenge the foundations of the post-war order established by the Cairo and Potsdam Declarations. Any breach of the "Three Non-Nuclear Principles" would directly undermine the global Nuclear Non-Proliferation Treaty (NPT) regime.

3. Elevated Risks in the Taiwan Strait: Frequent rhetoric among Japanese politicians suggesting "a Taiwan contingency is a Japanese contingency" and the militarization of the Southwest Islands as a springboard for intervention significantly increase geopolitical resistance and the risk of conflict spillover for China regarding its core interests.

4. Solidification of Bloc Confrontation: Japan is actively constructing "U.S.-Japan+" mini-lateral frameworks (e.g., Japan-U.S.-Philippines, Japan-U.S.-Australia), inviting NATO into the region. This promotes the "NATO-ization" of the Indo-Pacific and a "New Cold War" dynamic, marginalizing ASEAN centrality.

四、 结论与展望

IV. Conclusion and Outlook

【中文】

综上所述，日本“再军事化”已不再是单纯的内政调整，而是带有鲜明进攻性、外向性特征的系统性战略转型。这一趋势背离了日本人民渴望和平的主流民意（尽管国内反战抗议频发），正在将日本推向“能战国家”的危险边缘。

对于地区国家而言，必须高度警惕日本在历史修正主义道路上的倒退，坚决维护二战胜利成果与战后国际秩序。日本的军事松绑若无正确的历史观约束，不仅无法带来其宣称的“积极和平”，反而将成为亚太和平稳定的最大不确定因素。国际社会应敦促日本恪守和平宪法，停止在分裂亚洲的错误道路上狂奔。

In summary, Japan's "re-militarization" is no longer merely a domestic policy adjustment but a systematic strategic transformation characterized by distinct offensive and outward-looking features. This trend runs counter to the mainstream public sentiment in Japan that desires peace (despite frequent domestic anti-war protests) and is pushing Japan toward the perilous edge of becoming a "full-fledged military power".

For regional countries, it is imperative to remain highly vigilant against Japan's regression into historical revisionism and resolutely defend the outcomes of WWII and the post-war international order. Without the constraint of a correct view of history, Japan's military unfettering will not bring about the "proactive peace" it claims; instead, it will become the single largest uncertainty factor for stability in the Asia-Pacific. The international community should urge Japan to abide by its Peace Constitution and cease its reckless dash down the path of dividing Asia.
