Kilsoo Kenneth Haan (Korean: 한길수, Hanja: 韓吉洙, May 31, 1900 – July 1, 1976) was a Korean Nationalist, intelligence operative, anti-Japanese agitator, and both the source and translator of Kinoaki Matsuo’s contested and controversial book, The Three-Power Alliance and a United States-Japanese War (English: How Japan Plans to Win). Early life Haan was born in Chang Dan, Korea on May 31, 1900. He was five years old when his family joined the Korean immigration to Hawaii as plantation laborers. Despite his father leaving for Korea in 1910, he and his mother remained in Hawaii, where Haan continued his education. He attended the Korean Compound School and the Ka'iulani School until the 8th grade. In August 1920, Haan left Hawaii to spend a year preparing for the ministry at the Salvation Army Training School in San Francisco, California. Upon his return, he began his service as a Salvation Army representative on the island of Kaua'i. Haan rose through the ranks over the following six years to make Captain. Haan's religious career ostensibly came to an end in 1926 when he married a Korean woman from Honolulu named Stella Yoon and resigned from the Salvation Army, reportedly because his new wife's religious beliefs were in conflict with his service in the Salvation Army. After resigning, the couple returned to Honolulu. Career In the 1930s, Haan became involved with the Korean independence movement by joining the Korean National Association (KNA) of Hawaii. Pearl Harbor controversy On May 5, 1943, Haan appeared before Chairperson Samuel Dickstein’s House Immigration Committee on the repeal of the Chinese Exclusion Law. He gave testimony that his network of spies in East Asia had discovered evidence of the Japanese government's plan to end the war in China and re-deploy its naval assets to convoy a force of over 100,000 seasoned troops to invade Crescent City, California, "before Christmas". Legacy Haan's personal papers can be found in the University of California, Santa Cruz archives.
