In 1921 (Taisho 11), Ezaki Riichi created the nutritional snack "Glico" by using caramelized glycogen, a nutritious substance found in oyster broth that had been discarded by fishermen in the Ariake Sea. Since then, the company has released long-selling products such as Bisco, Almond Glico, and Pretz. In addition to sweets, the company is also active in areas such as frozen desserts, dairy products, cooked foods, food ingredients, and new materials, and sells its products not only in Japan but also around the world, including in Asia and Europe.
The company is currently headquartered in Nishiyodogawa Ward, Osaka City, and the Ezaki Memorial Museum located on the premises displays the history of the Glico Group, as well as numerous product packages, advertisements, Glico toys, and items related to the company's founder, Riichi Ezaki.
