Hello, Kyonichie. My name is Hirashin. I'm Japanese.
Where are you from?
Is your location Narita, Japan? Are you already in Japan?
If you want to enter a Japanese college, you have to read and write Japanese. Learning Japanese Kanji may be really hard.
You can't learn enough Japanese only by exchanging messages with Japanese people. I think you should go to a Japanese language school.
