It's happened several times: I'll be chattering away with a friend in Japanese, and they'll sneeze, and without even thinking about it I'll revert back to English to say "bless you." Is there a set phrase in Japanese I can use after someone sneezes?
Edited to add: started a bounty on this question a) for fun and b) to generate more answers to choose from. YOU's answer is not bad, but I'd like to give this question a chance to get some really good answers.
