There are supposedly about 500 commercial natto-producing interests in Japan, many of them small, local enterprises and farm cooperatives. This map covers about 130 natto companies, and is drawn from the membership lists of the Japan Natto Cooperative Society Federation. Please note that these names and locations were machine translated from Japanese.

(This map was made using the light version of the Google Maps engine.)

There seem to be only a handful of natto makers outside of Japan. If you’re aware of a natto producer other than the ones listed, by all means let me know.
