Self Intro

We wrote self-introductions for homework. The situation is:
"You are an exchange student at Osaka University in Japan. You have to introduce yourself in Japanese at a welcome reception that professors and students attend. Prepare a "self-introduction speech" that you can read from in case that you become too nervous to speak."
