I understand that -San is a formal way to address somebody. A unisex way of both Mr. and Mrs. Kun is a way to address males, but it's used with friends? I'm wondering about that. Now, Chan is very confusing. Is it also used with close ones, such as friends and family ? I know it's mainly targeted towards females, but apparently, it can be used with males too. Why males? In which situation would you address a male with -Chan ?
If it's someone who you meet for the first time, such as a random person, a future friend, classmate or colleague do you have to use -San, or could you use just -Kun or -Chan when first meeting them ? (someone from Japan wrote me a letter addressing me with -Chan, and I have never heard nor met this person before). Is it rude to call someone by their name and not use -San, -Chan or -Kun ? Well, if they're being addressed as -San and to stop that I'd imagine so, but what about if it's somebody you use -Chan or -Kun with often, as a friend? Do you have to use -Kun or -Chan in your family ? I know this is a lot to answer, but I have to live in Japan and I desperately want to know.
- Thank you
