はくしょん！ はっくしょん！ ハクション！ くっさめ！（this expression is used in Kabuki) ハクション大魔王の歌( the song of Hakushon-daimaou) http://www.youtube.com/watch?v=KZ4P4UpUAhg ------------------------------------------------------------------------------------- In addition after the answering.. I am sorry, I mis-read your question. I thought you were asking about how we say "sneezes" in Japanese. So the examples above are the variations of how to say "sneeze" in Japanese. But your question was about people's reaction for a sneeze. Takashi is right, we don't have a particular expression for it. However I would say.. ・風邪ですか？　"kazedesuka?" (did you chatch a cold?) ・大丈夫？"daijyoubu?" (alright?) instead of saying "bless you".. nothing special.. but we just dont have an expression. Once again, sorry for that confusing you.

I answered the same question a long time ago. http://www.italki.com/answers/question/25911.htm

In China,GuangDong,if only hit a sneeze words, will ask who is in you? If two above, if you have a cold?

my mother will say "好"in this case.The meaning is the same to bless you.But some people often say "are you ok?"with the suspicion for you being ill.

Usually, I'll keep silence~
