With a strong focus on training, the company has created a sales system in which employees can provide needed information. This had propelled Seijo's performance past other drug stores. Circle K oversees a network of convenience stores by entering into franchising agreements with existing small retailers and people wanting to open up a new store.
Most stores are in the Nagoya and Osaka areas.
Circle K is Japan's fifth largest convenience store company. Each store can order merchandise independently, and merchandise is delivered directly from suppliers in small lots. This allows each store to offer merchandise that matches the demands of local customers and thereby leads to higher sales. At franchised and directly operated stores alike, Circle K offers fast food, fresh food items, processed food items, non-grocery items and services. The company also has a small wrapping film operation.
