Banana in Days of Infamy
The derogatory term Banana was mentioned by Corporal Aiso to Takeo Shimizu, warning him and his men - in response to the news of a Japanese soldier who was assaulted and had his rifle being stolen by an unknown assailant - to never trust the Hawaiian locals, especially from the local Japanese, calling the latter Bananas. Shimizu was confused and later acknowledge the definition of the term from Aiso, citing that the Japanese may look like them, but they think like Americans. Shimizu was amused by the seemingly funny term and wondered who had come up with the word.
