Japanese participation in Peacekeeping Operations began in the balance between Constitutional and other legal constraints and demand for a larger international role in the post-Cold War era. The success of participation in the PKO in Cambodia and East Timor (UNTAC and UNTAET) created opportunities for further participation because of gradual acceptance of the participation of Self-Defense Forces (SDF) in UN PKOs. However, these successes did not change the fundamental constraints of the conditions for participation, namely the Five Principles on PKO participation. The arrival of the second Abe Administration, whose policy objective is to proactively contribute to peace, increased the expectation of Japan taking a much larger role in the UN PKOs, but the SDF participation South Sudan (UNMISS), which faced difficulties due to the lack of a firm ceasefire agreement and sudden breakout of civil war, raised questions of whether Abe’s policy was too aggressive. With the establishment of Peace and Security legislation, more proactive missions can be taken, but the necessity of national debate for building consensus about participating in PKOs still remains.

日本维持和平行动二十五年和自卫队在南苏丹的任务

日本参与维持和平行动的开始是在宪法和其他法律限制与在冷战后时代扩大国际角色的需求之间取得平衡。柬埔寨和东帝汶（东帝汶和东帝汶过渡当局）成功参加了维和部队，为自卫队（SDF）逐渐接受联合国维和部队的参与创造了进一步参与的机会。但是，这些成功并没有改变参与条件的基本限制，即关于维和行动参与的五项原则。第二个安倍政府的到来，其政策目标是积极促进和平，增加了人们对日本在联合国维和行动中发挥更大作用的期望，但是自卫队参加了南苏丹（南苏丹），由于缺乏坚定的停火协议和内战的突然爆发而面临困难，人们对安倍晋三的政策是否过于激进提出了质疑。随着《和平与安全》立法的制定，可以采取更加积极主动的任务，但是仍然需要进行全国辩论以就加入维和行动达成共识。
