In Japanese we can introduce ourselves using the following expressions:
Hi - こんにちは!
It means something like I have started the conversation- はじめまして
My name is ... - 私の名前は...です。
I wish you the best! (usu. translated to Nice to meet you! )- よろしくお願いします!
If we want to make a good impression, we can bow a bit at the end of your introduction. The order of the sentences is quite strict and do not forget the です after saying your name.
