The Fair Trade Commission has ordered Seven-Eleven Japan Co., the nation's biggest convenience-store chain operator, to stop preventing its franchise stores from selling food products at discount prices. The antimonopoly watchdog decided that the company took advantage of its dominant position vis-a-vis franchise stores and imposed its will in the pricing of articles, thus violating the Antimonopoly Law.

The FTC decision could lead to a change in the prevailing business practice in the convenient-store industry — placing a relatively wide assortment of articles in relatively large numbers at stores and selling them at prices recommended by the chain operators without discounting them. The decision has also reminded people of the large amount of waste produced by stores — an inevitable feature involved in convenience-store operations.

Some Seven-Eleven franchise stores wanted to sell food products such as box lunches, sandwiches and dairy products nearing their expiration dates at bargain prices. The FTC decided that the Seven-Eleven company pressured them not to do that. The company requires franchise stores to remove food products supplied every day from shelves two hours before their use-by dates and dispose of them. (The chain operator now offers to shoulder 15 percent of the wholesale prices of these products, but store owners still suffer losses.)

A survey of about 1,100 Seven-Eleven stores by the FTC shows that products worth an average ¥5.3 million are disposed of at each store every year. Since Seven-Eleven has some 12,000 stores, this could translate into ¥63.6 billion. It also means a large waste of resources.

The farm ministry says that factories, stores, restaurants and households discard 19 million tons of food every year. It estimates that 5 million to 9 million tons — comparable in amount to the 8.65 million tons of rice Japan produces yearly — was still fit for consumption at the time of disposal.

Encouraging convenience stores to discount food products that are approaching their expiration dates would help reduce waste, as would stores taking steps to ensure that supply more closely matches demand.

For their part, the central and local governments can exert pressure on the convenience-store industry by investigating how much food is being wasted and making the data public. They can also pass regulations that discourage the disposal of food products that have not reached their expiration dates, and require greater recycling of food products that could have further uses, such as compost and animal feed.
