Just in case you didn't know, the second name is their first name :3. Sorry if you do know.
I'm sorry, those are incorrect, RexRacer.-Hello/Hi- Ohaiyogozaimas
-Yo- Jahnay (only if you're a girl, if you're a guy you'll look stupid, I'd go with Ohaio if you're a guy)
-Thank you- Arigato
-Sushi bar ^_^- um... I should know but I don't ^_^
-Screw/**** you (Just to insult my friends in something they can't understand)- I like to go with Anata no Okasan... (Your mom)
Hello - This depends on the time of day, but こんにちは(konnichiwa) would be your best bet.
Yo - It would honestly just be "yo".
Thank you - ありがとう (arigatou)
Bathroom - informal=トイレ (toire) formal= お手洗い (otearai)
Sushi bar - I would recommend just saying すし屋 (sushiya)
Screw you - Um... the most common expression I've heard is 死ね (shine), which is essentially "go die".
