Welcome to Gaia! ::

I have plenty of questions..
1.) What is the word for the way they write, isn't that kanji?
2.) Also, what would be the word for the japanese words in english letters so I'm able to pronounce the japanese word correctly?
3.) If I wanted to write poetry in japanese, would someone help me translate it? I will pay attention of what word is what so eventually I would be able to write my poetry in japanese instead of english.
Please help me, I would really appreciate. I've already began learning and understanding things, but I'm not able to create sentences or anything, just words.

Ohayo. <-- Would this be romanji and the symbols are kanji? That's what I've been told from someone who speaks japanese. Also don't they read from right to left instead of left to right?
