Hi, i'm a canadian but, i spent 3 months in japan. some useful phrases that helped me out...
ikimasu = shall we go?
daijoubu = it's okay
daijobu desu yo = no problem
anatano ego wa totemo jouzu desu = your english is very good
(Japanese love to be told this... it's a nice thing to say, a lot are interested in learning the language.)
Watashino egao wa warui desu = my japanese is bad
gomen = sorry
gomenasai = really sorry
sumimasen = excuse me (very polite)
toire wa doko desu ka = where is the toilet
kore wa nan desu ka = what is this? (you can point)
egao ga hanasemasu ka = can you speak english?
watashino namae wa ____ desu = my name is ____
kirei = beautiful (you can use this a lot)
kawaii = cute
kowaii = scarey (be careful, they are similar but mean opposite things)
kaite kuremasen ka = could you please write it down?
ichi = 1
ni = 2
san = 3
yon = 4
go = 5
roku = 6
nana = 7
hachi = 8
kyuu = 9
jyuu = 10
jyuu ichi = 11
jyuu go = 15
jyuu kyuu =19
there's a pattern, easy
20 - 30
ni jyuu ichi = 21
ni jyuu go = 25
20-99 is a pattern too, very simple... say you want 54...its like saying, five ten four...or go jyuu yon.
sai = age
Watashino sai wa ni jyuu desu = I am 20 years old.
atsui = hot
samui = cold (temperature)
tsumetai = cold (to the touch)
matta ne = bye

okarada wo taisetsu ni = please take care of yourself (not widely used, but very polite)
chotto matte = one moment
chotto matte o kudasai = one moment please
o onegaishemasu = also means, please.
I know a lot more but I can't really think of specifics, if you want more help you can email me at firstname.lastname@example.org
Hope it helps you
