Aisatsu are “fixed” phrases that the Japanese use in particular situations. For example, when a Japanese person leaves the house, the person will always say いってきます. In response, people who stay at home will say いっていらっしゃい or いってらっしゃい to send them off. Knowing when to use and how to respond to these Aisatsu phrases is an important part of interpersonal communication in Japan. Aisatsu are very important in Japanese culture and society.

Gitaigo and Giongo (onomatopoeic words) are an important part of the Japanese language. Usually, they are two sounds that repeat, which makes them fun to hear and to say. These words can describe something, what it sounds like, or how you feel. There are also short terms in Japanese using body parts that convey all sorts of emotions.
