Hello!

I work at supermarket since I was high school student.

In the U.S.A  you need to be sixteen for almost all of the jobs here.

Hello there,

I'm going to say something about part time job in Japan.

We can do part time job when we become a high school student in Japan.

I work at a sushi restaurant.

How old are you when you do a part time job?

What kind of part time jobs do you do?
