What to say after someone sneezes


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?




Here are the results from a small poll on Facebook. Six native Japanese
replied. The results can be interpreted as:

  1. Don't say anything if you don't know them (6 people)
  2. If you know them you can ask if they're okay, if they've caught a cold or have allergies: "大丈夫？", "風邪引いたの？", "花粉症なの？", or something to that effect. (2 people)
  3. There's no such phrase equivalent to "bless you" in Japanese (2 people)

And here are the actual results (I didn't create any of the options, it was a
blank poll when I asked the question):
