There are many different words you can use to refer to yourself in Japanese. A peculiarity of casual forms of addressing people is that usage depends on your relation to the person you’re addressing. The impression you make on the person you’re talking to will be different depending on the words you use. Men commonly use “ore” or “boku” to refer to themselves in casual situations. “Ore” is used with close friends and family members, as well as with younger people. It gives the impression that you don’t care much about what others think of you. “Boku” sounds as if you have good manners and are well brought up, but also sounds a little childish. “Jibun” is also sometimes used by men. Since it was originally used by soldiers, it creates a polite impression. Women generally use “watashi” or “atashi.” “Watashi” is standard. It creates a feminine impression among those you are close to. “Atashi” creates a more casual impression than “watashi.” The majority of women use this with their friends. Men sometimes use “watashi” in formal situations, such as business meetings. Standard polite conversation / Casual expressions (man): I’m hungry.
