Japońskie terminy

DOMO ARIGATO - thank you (formal); dziękuję
DOMO ARIGATO GOZAIMASU - thank you very much (very formal); dziękuję bardzo
DOMO ARIGATO GOZAIMASHITA - thank you very much, even more formal than the very formal one above; dziękuję bardzo
GOMEN NASAI - I'm sorry; przepraszam, bardzo mi przykro, proszę mi wybaczyć
GOCHISOSAMA-DESHITA - dziękuję - po posiłku (to było bardzo dobre)

OGENKI DESUKA? - How are you?; Jak się masz?
OHAYO GOZAIMASU - good morning, dzień dobry
ONEGAI SHIMASU - please (when asking for something, usually as in “Please, let’s practice together”); proszę, naucz mnie
OSHIETE (KUDASAI) - "(please) teach me", such as a polite way to get a game with an older better player at a Go club, or before keiko with a visiting high ranked kendo sensei

Onegai shimasu is used when asking someone to do something for you, but unlike kudasai, which needs to be attached to the verb, onegai shimasu can stand by itself, such as in giving an item to buy to the cashier, or to a waiter to get a dirty plate removed, or as an additional exhortation after the initial please, as in "Oshiete kudasai. Onegai shimasu." Yarimasho-ka might also be better for "Let's practice (play) together, shall we?".

ONEGAI OTSUKARESAMADESHITA - a thank-you that is used after training
O TSUKARE SAMA DESHITA - you have become tired (because of the hard work you have done teaching), an expression of thanks
