Honorifics-
San:
The most common honorific and is a title of respect. It is used for the surnames or given names of both males and females. Although in translation san is usually rendered as a common courtesy title like “Mr.” or “Ms.”, unlike these it is never used in self-reference. Using san to refer to oneself makes one appear childish or incredibly vain.
Kun:
An informal honorific primarily used towards males (it is still used towards females, but rarely). It is used by persons of senior status in addressing those of junior status, by males of roughly the same age and status when addressing each other, and by anyone in addressing male children. It can also be used by females when addressing a male that they are emotionally attached to.
Chan:
Is an informal version of san used to address children and female family members. It may also be used towards animals, lovers, intimate friends, and people whom one has known since childhood. Chan continues to be used as a term of endearment, especially for girls, into adulthood. Parents will probably always call their daughters chan and their sons kun, though chan can be used towards boys just as easily.
Senpai:
Is used to address senior colleagues or mentor figures, e.g. students referring to or addressing more senior students in schools, junior athletes more senior ones in a sports club, or a mentor or more experienced or senior colleague in a business environment. As with English titles such as Doctor, senpai can be used either by itself as a title, or with a person’s name in place of san.
Kohai:
The reverse of Senpai, used to refer to juniors.
Sensei:
Used to refer to or address teachers, practitioners of a profession such as doctors and lawyers, politicians, and other authority figures. It is used to show respect to someone who has achieved a certain level of mastery in an art form or some other skill. For example, Japanese manga fans refer to manga artists using the term sensei. The term is used similarly by fans of other creative professionals such as novelists, musicians, and artists.
Sama:
The formal version of san. This honorific is used primarily in addressing persons much higher in rank than oneself and in commercial and business settings to address and refer to customers. It also appears in words used to address or speak of persons or objects for which the speaker wishes to show respect or deference, such as okyaku-sama (customer) or Tateishi-sama (a stone idolised as a deity). Additionally, Japanese Christians will refer to God in prayer as Kami-sama and Jesus as Iesu-sama.
Shi:
Used in formal writing, and sometimes in very formal speech, for referring to a person who is unfamiliar to the speaker, typically a person known through publications whom the speaker has never actually met.
