Natto originated in the Qin and Han Dynasties.

The ancient Japanese book "Wahan Sancai Tuhui" records: "Natto has been produced since the Qin and Han Dynasties." Tempeh began in China, and Japan also called natto "tempeh". There is also the word "豉". Since tempeh was made in the temple of the monks and then stored in urns and barrels, it was later spread to Japanese temples from the Qin and Han Dynasties by Zen monks. Therefore, natto was first developed in the temple, so it is also called "Tang Natto" or "salty natto".

Subsequently, natto was developed according to the local environment. For example, in Japan, doenjang is used instead of tempeh, or soy sauce is used instead of tempeh juice. In Japan, based on the characteristics of each region, local specialties such as Dairyuji natto, Daitokuji natto, Ikkyu natto, Daifukuji's Hamana natto, Goshenji's Yatsuhashi natto, etc. are passed down.
