戦後復興期間 (Sengo Fukkou Kikan), or the post-war reconstruction period, refers to the era in Japan following World War II, roughly from 1945 to the early 1950s. This period was marked by significant societal and political challenges as Japan sought to rebuild its economy, infrastructure, and social systems after the devastation of the war. Key elements of this era included the influence of U.S. occupation policies, the emergence of new democratic institutions, and widespread social reforms aimed at revitalizing Japanese society and addressing the needs of its citizens.
