Japanese holdouts or stragglers were Japanese soldiers in the Pacific Theatre who, after the August 1945 surrender of Japan ended World War II, either adamantly doubted the veracity of the formal surrender due to strong dogmatic or militaristic principles, or simply were not aware of it because communications had been cut off by the United States island hopping campaign.
They continued to fight the enemy forces, and later local police, for years after the war was over. Some Japanese holdouts volunteered in the Vietnamese Independence war and Indonesian Independence war to free Asian colonies from Western control, which had been one of Imperial Japan's alleged goals during World War II.
Intelligence officer Hiroo Onoda, who was relieved of duty by his former commanding officer on Lubang Island in the Philippines in March 1974, and Teruo Nakamura, who was stationed on Morotai Island in Indonesia and surrendered in December 1974, were the last confirmed holdouts, though rumors persisted of others.
- Captain Sakae Ōba, who led his company of 46 men in guerrilla actions against US troops following the Battle of Saipan, did not surrender until December 1, 1945, three months after the war ended.
- Major Sei Igawa (井川省) volunteered as a Viet Minh staff officer and commander. Igawa was killed in a battle with French troops in 1946.
- Navy Lieutenant Hideo Horiuchi (堀内秀雄) volunteered as an Indonesian volunteer Army Lieutenant Colonel. Horiuchi was arrested by Dutch troops on August 13, 1946, while his wounds were treated in a village after the battle with Dutch troops.
- Lieutenant Ei Yamaguchi and his 33 soldiers emerged on Peleliu in late March 1947, attacking the Marine detachment stationed on the island. Reinforcements were sent in, along with a Japanese admiral who was able to convince them the war was over. They finally surrendered in April 1947.
- On May 12, 1948, the AP reported that two Japanese soldiers surrendered to civilian policemen in Guam.
- Yamakage Kufuku and Matsudo Linsoki, two IJN machine gunners, surrendered on Iwo Jima on January 6, 1949.
- Major Takuo Ishii (石井卓雄) continued to fight as a Viet Minh adviser, staff officer and commander. He was killed in a battle with French troops on May 20, 1950.
- The AP reported on June 27, 1951 that a Japanese petty officer who surrendered on Anatahan Island in the Marianas two weeks before said that there were 18 other holdouts there. A U.S. Navy plane flew over the island indeed spotted eight or nine Japanese soldiers on a beach waving white flags. However, the Navy remained cautious as the Japanese petty officer had warned that the soldiers were "well-armed and that some of them threatened to kill anyone who tried to give himself up. The leaders profess to believe that the war is still on." The Navy dispatched a seagoing tug, the Cocopa, to the island in hopes of picking up some or all of the soldiers without incident. The Japanese occupation of the island inspired a movie.
