I feel pretty silly asking this question but it's really bugging me. I'm going to Japan, alone, for two weeks or so in June. I am trying to make this a very Japanese experience, and I have been trying to pay careful attention to etiquette rules.

My problem is that my nose tends to run any time I eat anything hot, whether that means spiciness or temperature. I know not to blow my nose in public, but what are my options? I can't get up from the table every two minutes. Do I just sit there sniffing every ten seconds for forty-five minutes to an hour? May I discreetly (and silently) wipe my nose with my napkin or something from time to time? Or am I just going to have to eat nothing but cold food and, worse, do without wasabi for the whole time I'm there?

What's the Japanese way?

Thanks for putting up with my silly question.
