At school, he and his classmates were required to recite the Pledge of the Imperial Subjects, promising to “serve the Emperor with united hearts.” Lee, like all citizens, had to forsake his Korean name and adopt a Japanese one.

People were even expected to give up Korean hairstyles, cutting off their braids and topknots.
