Thank you to everyone who responded. It sounds like my best strategy is to let the family know I do not drink prior to our visit, and to be careful to ask for water or other non-alcoholic drink that I know they have on hand. I expect they family we will be staying with will be very understanding, but I will likely practice (so I learn) doctor stop in Japanese so I can have use it in other circumstances if I need to.
I very much appreciate everyone's help.
