What are the differences of calling your name in Japan ending with kun, chan, san, etc?

Some responses so far are slightly off. Sama is used when talking to customers, over the phone, or to someone really high up who's probably not in your in group. San is the 'normal' way of addressing people, but you don't want to call a doctor or teacher this. If you go to a place of business as the customer, chances are that they'll call you -sama and you can call them -san. A doctor or teacher, though, you always call -sensei. Kun is ONLY for boys, and only for boys under your age/status. I don't think I've ever heard two males call each other -kun. It's always A calling B -kun, and B calling A -san. If you're going to call someone -kun, a good measure is that it's always OK if they're in or under college. If you're not sure, just say -san. -kun can be used with first or last names, with the first name version being much more familiar. Chan has various uses. With the full last name, it's for little girls, up to 10 yrs old or so. With the first name you can use it on girls through their 20s or so depending on your relationship. However, boys can also have -chan attached to their FIRST names. When they're younger this can be a sign that they're not as manly as the other boys, but adult males also have it attached, sometimes out of habit, and sometimes in a slightly derogatory sense. In the latter case it's not an insult, but a kind of reminder of status. Some examples: Matsumoto Aiko (girl) could be called Matsumoto-chan through elementary school, or Matcchan through high school; in this case people could call her Matcchan for a longer time since it could be easier to remember than Ai-chan, which they could also say. Matsumoto Masaaki (boy) would be called Matsumoto-kun or Masaaki-kun through college, but he could take on the name Maa-chan (from Masaaki) depending on factors. When they enter the work force, Aiko will be called Matsumoto-san; Masaaki will be called Matsumoto-kun (or Maa-chan) by his superiors, but Matsumoto-san by customers. HTH!

It's "Japanese" to call someone by their last name if you do not know them very well. This is why when the Japanese introduce themselves, it is always last name first and first name last. Unless you know that person well, it's more polite to use their last name. Sama is for your lord or someone extremely high in social status. Sensei is attributed to teachers, doctors, and the like. San is most commonly used. It works as Mr., Mrs., Miss, etcetera. Kun is used to address people younger than you as Mr., Mrs., Miss, and etcetera. Chan is for when you are talking to your buddies, pets, children, or lovers as it is a rather "cutesy" honorific. A lot of the time -chan is preceded by the person's first name; sometimes a shortened version or nickname of the first.

san=mr.,ms.,miss kun=children,people younger then you chan=is used for girls

Japanese people are usually pretty accepting of foreigners not knowing the culture, but they are thrilled when you do your research. San should really be used all the time when meeting new people with their last names for example, Tanaka-san. If you know the person but they are older than you (and they've said it's okay to use their first name), you can call them by their first name ending with san to be respectful (ex. Hiromi-san). For young children, chan is used with the first name (ex. Hana-chan). Chan can also be used affectionately with good friends.

call everyone by their surname plus san. it may be th easiest for you and is the standard. mainly used for adult males and females. chan is used for someone younger than you, kun is usually used for a small boy. chan and kun can be used with the first name eg lisa chan. san is only used with a surname

How about "chee_bai"?

Just say "Watashi NO Otaku des" to anyone who's attention you want..

ok, here are some more and rare examples you would never know from dictionaries. SENSEI --- "Yo prof!" Its like to call a person who you dont think he/she is a profesor but rather estimate him/her lower than you. SHACHO --- "Shacho!" this may comes old fashioned now but spieler had used to invite customers into a bar or something on the street.
