みんなさん、
For my trip to Japan I'm participating in a homestay. I would like to send them a little "getting to know you" email before my stay thanking them for inviting me into their home for the upcoming trip, among other things.
Does anyone have any suggestions for good openers in Japanese and maybe some formal phrases/sayings to ingratiate one's self with the family? I'm still a beginner in the language, so any help would be immensely appreciated!
