日本刑法的一体化防卫理论对于不法侵害结束后的防卫行为采用整体评价原则，认为不仅防卫人对正在进行的不法侵害可以成立正当防卫，而且不法侵害结束后，由于所造成的法益风险没有消除，此时进行防卫的行为可能被一体化评价为正当的防卫行为。本文在考察日本一体化防卫理论发展的基础上，结合重要判例的分析，探索日本刑法对一体化防卫行为的理论认定和实践标准，借用一体化防卫理论的优势，为我国理论和实践提供借鉴；同时结合我国刑法具体情况，明确能够将防卫行为正当化的规范界限和一体化评价的要件。

The integrated defense theory of the Japanese Criminal Law adopts the principle of overall evaluation for the defensive behavior after the illegal infringement ends. It believes that not only the defender can establish a legitimate defense against the ongoing illegal infringement, but also after the illegal infringement ends, the risk of legal interest caused by it has not been eliminated. At this time, the act of defending may be evaluated by the integration as a legitimate act of defense. Based on the investigation of the development of integrated defense theory in Japan and the analysis of important precedents, this article explores the theoretical identification and practical standards of integrated defense behavior in Japanese criminal law, and borrows the advantages of integrated defense theory to provide reference for my country's theory and practice; At the same time, combining the specific circumstances of my country's criminal law, clarify the normative boundaries that can justify the defensive behavior and the requirements for integrated evaluation.
