Daiei Inc. said Tuesday it made more than 40 billion yen in revenue from an eight-day nationwide sale commemorating the Daiei Hawks winning the Japan Series baseball championship.

The revenue from the special sale was up about 100 percent from the same eight-day period a year earlier, officials of the supermarket chain operator said.

When combined with revenue from the special sale held after the Hawks grabbed the Pacific League pennant, total sales reached about 80 billion yen, the officials said.

Daiei's same-store sales had fallen for 13 consecutive months on a year-on-year basis until September. But the special sales are expected to boost revenue for October by about 30 percent, the officials said.

Daiei's Himonya store in Meguro Ward, Tokyo, posted the highest revenue during the campaign, at 620 million yen, followed by the Koshien store in Nishinomiya, Hyogo Prefecture, at 550 million yen.
