摘要：日本的天皇制可以说是世界历史上存在时间比较长的君主制度。它作为一种制度，经历了古代、近代、现代三个不同的发展阶段，至今已有1300多年的历史。并且在这么长的时间中，其皇室从未被取代，天皇制也从未间断，这在王室、王朝兴亡更迭异常激烈的世界历史中是极其罕见的，可以说绝无仅有。天皇制可以说既是历史学的问题，也是政治学的问题，准确客观地研究分析天皇制，可以让我们更加深入准确地了解日本，从而制定出科学的对日政策。因此，本文将着眼于日本天皇制得以续存至今的原因，从日本的国内因素及国际因素两个大的方面入手，来对这一问题进行一些探讨。其中，国内因素又分为自然环境、文化环境、精神构造、社会结构、天皇制自身特征等方面，国际因素就是二战后的国际形势，主要是其中的美国因素和中国因素。
