Don Quijote Holdings Co. Ltd. CEO Koji Ohara said the Japanese general merchandiser would be interested in buying Walmart Inc.'s supermarket subsidiary, Seiyu, if the American retailer puts it up for sale, Reuters reported Aug. 13.

According to the report, Don Quijote is planning to expand its presence in its domestic market and is targeting 500 stores in Japan by 2020 from the 420 it has at present. The company, however, has struggled to find sites in some areas, according to the report.

"In addition to its human resources, Seiyu has many locations that you cannot get your hands on," Ohara said.

Walmart in July refuted reports that it has plans to sell Seiyu, saying it was not in any discussions with prospective buyers.
