There are some things that cannot be changed by the passage of time.
There are things that must be attempted as time goes by. Our company is a manufacturer of authentic handmade amanatto (sweet soybeans) cooked over an open flame.
Since its establishment in 1935, TSUKAMOTO Co., Ltd. has continued to build on its history and evolve its manufacturing technology while preserving traditions.
In order to meet the needs of our customers, we, as a manufacturer of amanatto (sweet soybeans) with our original sugar substitution processing technology, we aspire to create a new business model and new style within the industry.
Under our corporate philosophy of "Evolving Tradition", we will manufacture safe and reliable products with the aim of becoming a company that can meet the wishes of our customers.
We aim to create a new style of amanatto by utilizing new ingredients without being bound by the conventional concepts of amanatto.
In 1991, we obtained FSSC 22000 certification and are operating a food safety management system in pursuit of food safety and security.
By utilizing "open-flame cooking," a process we have maintained since our founding, we bring out the true flavor of the ingredients, resulting in a rich, deep taste. We hope you will enjoy our Sweet Potato Natto, which can be enjoyed by people of all ages.
We use sweet potatoes from Ibaraki Prefecture that are known for their proper cultivation history management. We do not use any sugar and food additives. We use multitol (reduced maltose starch syrup) that has 30% less calories than conventional sugar. It is a product born from our collaboration with Sagami Women's University (Sagamihara City, Kanagawa Prefecture). Aside from the name of the product, our mascot "Imosho-kun" was also designed by female college students.
