Who is Chief of Police from Lost Names: Scenes from a Korean Boyhood and what is their importance?

Chief of Police is the name of the officer in charge of the city. He greeted the boy's father on the day the Japanese registered their new names. The boy's father gave an Inspector his chosen family name "Iwamoto", which means "Foundation of Rock" from the Bible. The boy's father was chairman of the Committee to take over the city. Father negotiated with him and accepted surrender from the Chief of Police, who officially turned over the city to the Korean residents by handing over his saber to the chairman and boy's father.
