由於生育率及死亡率的降低，導致人口老化的問題。因此，近年來，與年長者相關議題備受重視，而成年監護制度即為當代重要課題之一。本文先檢視我國成年法定監護制度之現況，再輔以日本之成年法定監護制度作為對比，並從而檢討我國現行法有何不足之處；再觀察我國之成年意定監護制度，並比較其與日本之成年意定監護制度有何不同之處，進而檢討我國法之不完善之處。
我國之成年監護制度分為成年法定監護及成年意定監護兩種，雖成年法定監護制度已存在甚久，但仍有不完善之處，例如監督機制過於被動等；而成年意定監護制度，係於2019年始公布施行，亦有其不足之處，例如未明文不得委任代理之事項、無監護監督人之設計。因此本文透過比較研究之方式，將我國與日本之成年監護制度相比較後，參考其優點，並避其缺點，針對我國之不足之處提出建議，期能提供參考，使我國之成年監護制度更加完善。
