Introductions in Japan run to a formula, and using it marks you as someone who has bothered. Name, where you are from, then yoroshiku onegaishimasu — a sentence with no English equivalent, somewhere between “please treat me well” and “I look forward to this”.

The formula matters more than fluency. A visitor who says their name badly but closes with yoroshiku onegaishimasu has done the thing correctly. Family name first is normal in Japanese order, and -san is attached to other people’s names, never to your own — introducing yourself as “Smith-san” is the classic beginner’s slip.
