Self introduction

Hello, nice to meet you. My name is Tsukuru Miyakawa. I'm 18 years old. I live in Tokyo now also I live with my parents and a sister.
I am a student of International Christian University. I study the economics in the university and I want to decide it as my major subject.
I had never been abroad until this time so I feel everything I see in the U.S is fresh and impressive for me but there are many things I don't get used to yet. So I am a little tired.
I don't have my hobby, but I like playing basketball. I joined the basketball team when I was a high school student. So I often play basketball in my university.
I don't have confidence in my English, but I want to improve my English skill in this program. So I will try to do my best.

Thank you
