Japanese for the tea room

Learning the Japanese words during tea class is not necessary, but it does help with the discipline of learning something new. At the request of my current students here is the basic Japanese for receiving tea properly in the tea room:

Opening salutation (aisatsu), entire class:
"Ohayo gozaimasu [morning] (OR “Konnichi wa [daytime],” “Konban wa [evening]”) Okeiko yoroshiku onegai itashimasu." (Teacher, please instruct us)

Closing salutation (aisatsu), entire class:
"Sensei, okeiko domo arigato gozaimashita." (Thank you for the lesson)

To the host, after being invited to be the guest:
"Yoroshiku onegai itashimasu."

To the teacher before being invited to be the guest by the host:
"Sensei, okyaku okeiko yoroshiku onegai itashimasu." (Please do me the favor--i.e. of instructing me)

When the host invites you to take your sweet:
"[Okashi] chodai itashimasu." (I will partake of this sweet)

When you bring the bowl back to your place:
If there is a guest to your right (who has already drunk tea):
"Oshoban itashimasu." (May I join you?)

If there is a guest to your left:
"Osakini." (Excuse me for going first)

To the host:
"Otemae chodai itashimasu." (I will partake of your temae-- i.e., the tea and its preparation)

To stop the host from making more tea (spoken as the host empties the rinse water into the kensui):
"Oshimai kudasai." (Please conclude)
