The origin of natto

Natto has been eaten in Japan for 1000 years. According to textual research, natto originated in China and spread in Japan. Natto was made in China during the Qin and Han Dynasties (2265438 BC+0-220 AD). It is a bean product fermented by Bacillus subtilis, which is sticky, smelly and slightly sweet. There is a related record in the ancient Japanese book "Three Things in Hehan": "Since the Qin and Han Dynasties, there has been natto. Douchi originated in China and was once called "black bean" in Japan.

In the Nara era of Japan (about 7 10), natto was brought to Japan by Zen monks, and its original name was "black bean". Because fermented beans are often stored in jars or barrels after being produced in monasteries, they gradually become "Tang natto" or "salty natto". Natto literally means "Suo Na's bean". Natto was originally made in the kitchen of a temple and is an important source of nutrition for vegetarian monks. Because the kitchen in the temple is called "Suo Na", it is called natto.
