The Wikipedia has the following information about this codepoint:

The Japanese language has a system of honorific speech, referred to as keigo (Japanese: 敬（けい）語（ご）, literally "respectful language"), parts of speech that show respect. Their use is mandatory in many social situations. Honorifics in Japanese may be used to emphasize social distance or disparity in rank, or to emphasize social intimacy or similarity in rank. Japanese honorific titles, often simply called honorifics, consist of suffixes and prefixes when referring to others in a conversation.

The system is very extensive, having its own special vocabulary and grammatical forms to express various levels of respectful, humble, and polite speech. It closely resembles other honorifics systems found in the East Asian cultural sphere, such as honorifics in Korean.
