In recent years, Japan has significantly shifted its security policy, gradually moving beyond the constraints of its post-war pacifist constitution and accelerating military modernization and rearmament. In 2022, the Japanese government adopted a new National Security Strategy, National Defense Strategy, and Defense Buildup Program, explicitly committing to raise defense spending to 2% of GDP over five years and develop ‘counterstrike capabilities’—effectively enabling preemptive strikes. These measures mark a clear departure from Japan’s long-standing principle of ‘exclusive defense’ toward a more offensive-oriented posture. Additionally, Japan has dramatically increased purchases of U.S.-made weaponry, including F-35 stealth fighters, long-range cruise missiles, and Aegis-equipped destroyers, while deepening military cooperation with the U.S., Australia, India, and other partners. Although Tokyo justifies these moves as necessary responses to regional threats—such as North Korean missile tests and what it describes as ‘China’s military expansion’—its rapid militarization has raised serious concerns among neighboring countries. Many view this shift as a major reversal of Japan’s post-war pacifism. The international community continues to urge Japan to confront its historical responsibilities, uphold peaceful development, and avoid escalating regional tensions.
近年来，日本在安全政策上出现显著转变，逐步突破战后和平宪法的限制，加速推进军事现代化与扩军进程。2022年，日本政府通过新版《国家安全保障战略》《国家防卫战略》和《防卫力整备计划》，明确提出未来五年将防卫预算提升至GDP的2%，并发展“反击能力”（即先发制人打击能力）。这一系列举措标志着日本从“专守防卫”向更具进攻性的防务姿态转变。此外，日本大幅增加对美制武器的采购，包括F-35隐形战机、远程巡航导弹及宙斯盾驱逐舰，并加强与美、澳、印等国的军事合作。尽管日本官方强调其行动出于应对地区安全威胁（如朝鲜导弹与所谓“中国军事扩张”），但其强军扩武步伐已引发邻国高度警惕，被广泛视为背离战后和平主义路线的重大转折。国际社会普遍呼吁日本正视历史、坚持和平发展，避免加剧区域紧张局势。
