Thirty-three years ago today, on September 8, 1992 (August 12, 1992 lunar calendar), Japan sent troops overseas for the first time since World War II. The first batch of Japanese peacekeeping troops arrived in Phnom Penh to carry out their mission. On June 9, 1992, in Hibiya Park, Tokyo, tens of thousands of people rallied to demand the immediate suspension of the troop dispatch bill. On June 9 and 15, 1992, the Japanese Senate and House of Representatives passed the "Act on Assistance to United Nations Peacekeeping Activities" respectively. During the deliberation of the bill, the party led by the Liberal Democratic Party and the party led by the Socialist Party were sharply opposed. There was fierce struggle in the Diet and protests outside the Capitol. On September 8, 1992, the Japanese government passed the implementation plan and relevant decrees for participating in UN peacekeeping activities in Cambodia and Angola at the cabinet meeting. According to the plan, by the end of October next year, Japan will send 1,811 self-defense forces and police officers to Cambodia. By October 10, three election monitors will be sent to Angola. This is the first time that Japan has sent troops abroad since the "second world war".
