Natto is a traditional Japanese food. It's very popular in Japan. My two little kids love natto, and we eat it at least twice a week. If you ever come to Japan, I highly recommend that you try it. You might be surprised by its sticky texture and strong aroma, but it's very healthy and worth trying!
One more thing. In Japan, it's okay to make some noise while eating. Slurping noodles like soba and udon is a normal part of our food culture. So don't worry if you make some noise while eating natto, either.
