Toraya-Yoshisue was founded in 1801. Originally, the company was a manufacturer of sake barrels. However, they came up with the idea of creating senbei shaped like sake barrels to give as souvenirs to travelers. This marks the beginning of barrel-shaped senbei. In the Koshi Senbei, peanuts are sandwiched within the dough, making them even more flavorful and fragrant.
