How do you eat Japanese natto?

Question:

I'm going to a Japanese restaurant tonight, and I'd like to try natto (the sticky fermented soybeans). How am I supposed to eat them?

Answer:

Natto is a traditional Japanese food made from fermented soybeans. It is usually eaten as part of a traditional breakfast in Japan but is also enjoyed for dinner. Natto is an acquired taste due to its powerful smell and strong taste. It was not something I enjoyed when I first moved over to Japan, but something I grew to appreciate over time. I love my natto mixed with green onion, soy sauce and mustard (karashi) and then poured over a bowl of rice. It is also really good in Japanese curry.
