はじめましょお。 hajimemashoo pronounced; hah jee meh mah show This means "let's begin" and is said by the teacher.
きりつ、きいおつけ、れい、ちゃくせき kiritsu, kiotsuke, rei, chakuseki pronounced; key reetz, kyots skay, ray, chalk sekee This is what Japanese students do at the beginning of class after arriving and bowing to show respect to the teacher. Generally, a student who has been predesignated says these. They mean "Stand, attention, bow, sit." The students and maybe the teacher will say "good morning" or "おはようございます" (ohayou gozaimasu) when they bow. However there is some changes. In some cases, "きりつ" and "ちゃくせき" may be changed. This may also be said at the end of class. Remember that Rs in Japanese are hard Rs, so make sure to touch the top of the mouth with your tongue when you say it.
