On this day, 43 years ago, November 10, 1982 (September 25, 1982 in the lunar calendar), the US and Japanese forces conducted joint exercises for the first time. On November 10, 1982, the first joint actual combat exercise between the Japanese Ground Self-Defense Force and the U.S. Army began at the Higashi-Fuji Exercise Ground in Shizuoka Prefecture. "Tokyo Shimbun" believes that since the three services of Japan and the United States, the army, sea and air, have successively conducted joint exercises,"the Japan-US defense system has entered a new stage." Participating in this joint exercise, the Japanese side is about 500 people from the 31st Infantry Regiment of the Eastern Front Army; the United States side is about 200 people from the 9th Infantry Division. The U.S. Army combat troops came to Japan for the first time in 25 years since the withdrawal of U.S. troops from Japan in 1957. According to the "Daily Shimbun" report, when talking about the reasons for the increase in joint training of Japanese and US troops, the Japan Defense Agency said that since U.S. President Reagan took office, in order to achieve the effect of suppressing the Soviet Union, it has been active in joint training of Japanese and Japanese troops; the Japan Defense Agency "in order to maintain the posture of responding immediately if something happens, it will actively conduct such joint exercises in the future." The Socialist Party of Japan and others are critical of this position of the Japan Defense Agency. Kazuo Asushida, chairman of the Socialist Party, said: "We can only think that the Self-Defense Force has become a military subordinate to the US military, and it will transform Japan's defense system from exclusive defense to offensive defense."
