> Politics in Japan in the post-war period has largely been dominated by the ruling Liberal Democratic Party (LDP), which has been in power almost continuously since its foundation in 1955, a phenomenon known as the 1955 System. Of the 31 prime ministers since the end of the country's occupation, 24 as well as the longest serving ones have been members of the LDP.[4] Consequently, Japan has been described as a de facto one-party state.[5] https://en.m.wikipedia.org/wiki/Politics_of_Japan https://en.m.wikipedia.org/wiki/Politics_of_Japan
