Natto is a traditional Japanese fermented food. Natto-bacteria (aerobic bacillus) is added to steamed soybeans in order to make natto. It has special sticky and gooey texture and strong smell. Japanese people say that natto is very stringy and has a bad smell, but there is also amanatto (sweet natto), which is very sweet and doesn’t have a smell. Japanese people eat amanatto as a cheap sweet. Elderly people like it especially, because it is soft and delicious.
