I'm learning Japanese too! Believe me, having a tutor makes everything so much easier!

Ohayo = Good morning. (If you're being polite, add 'gozaimasu' on the end) *Pronounced 'go-zai-mass'*

Konnichiwa = Hello/Good day. *Kon-neechee-wa*

Kombanwa = Good evening. *Kom-ban-wa*

Watashi wa <Your name> desu = My name is... (If you're a boy, you can say 'boku' instead of 'watashi', or if you're a girl, you can say 'atashi' instead. I say 'atashi') *Wa-ta-shee-wa- <Your name> -dess*

Nandemo tabemasu = I eat everything. (I found this incredibly useful when I went to Japan) *Nan-deh-mo-ta-beh-mass*
