introduce myself

I'm Kazuma Kitayama. 
I live in Osaka-Japan. 

I'm 18 years old. 

I want to speak good clean English in America.

Note: 

I am -> I'm.

You must always end sentences with a period.

-> .

Names of people and languages are always capitalized.

kitayama -> Kitayama.

english -> English.

"Good" or "fluent" works better than "clean." 

Good job! がんばってね！
