How do you address someone in Japanese?

Answer 1

Generally speaking to be safe, you address them with the honorific "-san" if you know their name (if you don't know them very well, just use their last name with the honorific). If you don't know their name, there are other terms you can use.

Answer 2

In Japanese, you can address someone by using their name followed by a title like "san" (Mr./Ms.) in a formal setting. For example, "Tanaka-san" would address Mr. Tanaka in a respectful manner. In more casual situations, you can simply use their name without any title.
