Impact: The "55-year system" made the Liberal Democratic Party in power for a long time and firmly controlled Japan's politics and economy, thus putting Japan on the road of economic priority and creating a Japanese miracle. However, under the long-term one-party dictatorship, Japan's political, economic and social development finally entered a bottleneck and eventually broke out in all aspects.

Introduction: 55-year system (Japanese original 55-year system pen name ごじゅぅごねんたぃせぃぃぃぃ𞊣𞊣) The term "55-year system" first appeared in the paper "1955 の Political System" published by the political scholar Sheng Weijun in 1964 (ThoughtNo. 1964). During the period of 1955, the conservative parties in Japan and the innovative parties in Japan joined forces to form a system characterized by the opposition between the Liberal Democratic Party, which represents the conservative forces, and the Socialist Party, which represents the innovative forces. It is called the 55-year system in Japanese history. Although it is a two-party system under the rule of law, it is actually a one-party ruling system of the Liberal Democratic Party under the surface of the two-party system. The 55-year system is an important part of postwar Japanese politics.
