Natto originated in various parts of Japan, and today Yokote City is one of them. During the military campaign of 1083-1087, which took place in Yokote City, farmers delivered boiled beans wrapped in straw to Minamoto no Yoshie's side, which was struggling with the supply of goods. The farmers tried it and found it tasty. This legend led to the erection of a monument in Kanazawa Park in Yokote City.
Mushrooms and wild vegetables, which are the main ingredients, are picked in spring or fall, stored in salted storage, and used after removing the salt when making natto soup. Because of the time-consuming nature of this dish, it has taken root as a dish for ceremonial occasions such as weddings and funerals.
