This report examines the characteristics and effects of the implementation process of the Japanese age-limit system to reflect on the Korean system. While the legal and institutional aspects may appear similar between the two countries, the processes of policy formation, adjustment, and decision-making differ, leading to variations in outcomes. In Japan, laws and policies serve as inherent and ultimate functions for coordinating social actions, whereas in Korea, they are perceived as external and constraining yet do not function as regulations for actors. The age-limit system is a challenge that our society needs to address, but limiting the discussion to specific legal frameworks can narrow the scope of the issue. The report highlights the need for more comprehensive policy discussions as various possibilities may be excluded and the outcomes may differ from expectations.
