Nattō

Natto ( (hiragana), 納豆 (kanji); nattō or nattou) is a traditional Japanese food made by fermenting soybeans. Natto is known for its strong musty smell and unusual slimy texture, which makes sticky strings when stirred and eaten. In order to balance some of the strong flavors, it is usually eaten on top of rice with mentsuyu, a soy sauce-based condiment, or Japanese mustard. Whether Natto is popular or not depends on regions in Japan. For example, eating Natto as a custom is not so popular in the Kansai region of Japan.
