Japanese Language Notes

Despite listening to over 30 lessons of Pimsleur's Japanese, I think the only phrases I've used are "arigato" ("thank you"), "do itashimashite" ("you're welcome"), "sumimasen" ("excuse me" or "sorry"), "wakarimasen" ("I don't understand") and "kyo wa" ("today": used when trying to get Hashin Tiger tickets). Overall, I've just been trying to get by on English since even if I am able to come up with something to say in Japanese, I won't be able to understand what they say.
