近期，日本军费开支跃居全球第三，引发国际社会广泛关注。根据斯德哥尔摩国际和平研究所（SIPRI）等权威机构数据，日本2023年度国防预算大幅增加，突破7万亿日元，占GDP比重接近1.3%，并计划在未来五年内进一步提升至2%。这一转变标志着日本在安全政策上的重大调整。长期以来，受和平宪法第九条限制，日本奉行“专守防卫”原则，军事发展相对克制。然而，面对地区安全环境变化——包括朝鲜导弹试射、中国军力增长以及俄乌冲突带来的全球战略不确定性，日本政府逐步强化自主防卫能力，并加强与美、澳等盟友的军事合作。值得注意的是，日本军费增长并非单纯用于武器采购，还包括提升网络、太空和电磁等新兴领域作战能力，以及改善自卫队人员待遇和装备更新。尽管如此，此举仍引发邻国对其军事走向的担忧，尤其考虑到日本近代历史背景。总体而言，日本军费跃升反映其从“被动防御”向“主动威慑”的战略转型，但如何在增强防卫与维护区域和平之间取得平衡，仍是其未来外交与安全政策的关键课题。
Recently, Japan’s military spending has surged to become the world’s third highest, drawing significant international attention. According to data from authoritative sources like the Stockholm International Peace Research Institute (SIPRI), Japan’s defense budget for fiscal year 2023 exceeded 7 trillion yen—nearly 1.3% of its GDP—and is projected to rise to 2% within the next five years. This marks a major shift in Japan’s security policy.Historically constrained by Article 9 of its pacifist constitution, Japan adhered to a “purely defensive” posture and exercised restraint in military development. However, amid evolving regional security dynamics—including North Korea’s missile tests, China’s growing military capabilities, and global strategic uncertainties highlighted by the Russia-Ukraine conflict—Japan has gradually enhanced its self-defense capabilities and deepened military cooperation with allies such as the U.S. and Australia.Notably, Japan’s increased defense spending isn’t solely allocated to weapons procurement; it also funds capabilities in emerging domains like cyber, space, and electromagnetic warfare, as well as personnel welfare and equipment modernization for the Self-Defense Forces. Nevertheless, this buildup has raised concerns among neighboring countries, given Japan’s historical legacy.Overall, Japan’s rising military expenditure reflects a strategic pivot from passive defense toward proactive deterrence. Balancing enhanced defense readiness with regional peace and stability remains a critical challenge for its future foreign and security policy.
