The way to Introduction

To introduce yourself in Japanese, this is an example :

Hajimemashite はじめまして

Namae wa Yuki desu　名前はユキです

19 sai desu　１９歳です

Yoroshiku onegai shimasu　よろしくお願いします

It means :

Hi (but hajimemashite just used in introduce)

My name is Yuki

19 years old

I beg your help

Hajimemashite not only used in front of the introduction, but also used in the end of introduction.

Example.

Yuki desu

Hajimemashite.

In socialization, namae wa usually not used anymore, they only say their name.

If you won’t to say your age, it’s okay.

Some of them, if they introduce themselves, say his/her age, status (already married or not), their blood type, and what enterprise/business they came from (this is because they are very proud of their business/enterprise and pride to be inside)

Must remember point is keep polite in attitude and words / grammar you used, because it’s very important for first meeting with Japanese.
