3. Businessmen taunt non-natives with the "natto challenge."
Japanese businessmen have a little fun at foreigners' expense with the "natto challenge." Since it's bad manners to refuse to try a food in Japan, pranksters will have prospective business partners visiting from out of the country try natto -- typically after a few rounds of sake. They'll extend a seemingly innocent invitation: "Try this -- foreigners can't eat it, you know."
