Colonel Baron Takeichi Nishi was an Imperial Japanese Army officer, equestrian show jumper, and Olympic Gold Medalist at the 1932 Los Angeles Olympics. He was a tank unit commander at the Battle of Iwo Jima and was killed in action during the defense of the island.

The 1932 Summer Olympics were an international multi-sport event held from July 30 to August 14, 1932, in Los Angeles, California, United States. The Games were held during the worldwide Great Depression, with some nations not traveling to Los Angeles; 37 nations competed, compared to the 46 in the 1928 Games in Amsterdam, and even then-U.S. President Herbert Hoover did not attend the Games. The organizing committee did not report the financial details of the Games, although contemporary newspapers claimed that the Games had made a profit of US$1,000,000.
