Japanese names in modern times consist of a family name (surname) followed by a given name. Japanese names are usually written in kanji, where the pronunciation follows a special set of rules. Because parents when naming children, and foreigners when adopting a Japanese name, are able to choose which pronunciations they want for certain kanji, the same written form of a name may have multiple readings. In exceptional cases, this makes it impossible to determine the intended pronunciation of a name with certainty. Even so, most pronunciations chosen for names are common, making them easier to read. While any jōyō kanji and jinmeiyō kanji may be used as part of a name, names may be rejected if they are believed to fall outside what would be considered an acceptable name by measures of common sense.

A given name is the part of a personal name that identifies a person, potentially with a middle name as well, and differentiates that person from the other members of a group who have a common surname. The term given name refers to a name usually bestowed at or close to the time of birth, usually by the parents of the newborn. A Christian name is the first name which is given at baptism, in Christian custom.
