The current "Mos Shake Coffee" was born around 1990 and has been a beloved standard product for over 30 years since then. ■ Osatsu Dokki "Osatsu Dokki," launched in 1985, has been loved by many customers and celebrated its 40th anniversary last year. Since its launch, it has been committed to the "deliciousness of sweet potatoes," offering sweet potato chips that allow you to enjoy the natural sweetness inherent in the sweet potato ingredient. By thinly slicing and frying sweet potatoes, a crispy texture is achieved. Furthermore, a great advantage is that since it uses sweet potatoes as they are, you can easily and deliciously supplement dietary fiber, which tends to be insufficient in daily life.
