umm. . . I guess I can suggest that you make sure you can properly pronounce things first of all.
Not many people in japan speak much english but it's worth asking if you need with directions or anything
Sumimasen, eigo ga hanashimasu ka?
Excuse me, do you speak english?
Sumimasen can also be used if you accidentally bump someone or if you need someones attention to ask a question.
Another important question would be
otearai wa doko desu ka?
where is the bathroom?
this is the base question for asking for directions to most things. ______ wa doko desu ka?
doko= where
Directional words.
These will be handy to know.
Right = migi
left= hidari
front/in front of= mae
back/behind= Ushiro
inside= Naka
on/above= ue
under= shita
near= soba
next= tonari
here= koko
there= soko
over there= asoko
more handy things
what is this, that, that over there.
this= kore (near you)
that=sore (near person you are speaking too)
that over there= are (far from both the speaker and listener)
_____ wa nan desu ka?
nan/nani = what
You will have to say thank you plenty of times i'm sure,
doumo arigatou
Umm. . .thats all i can think of right now. I hope that this was helpfull.
