Wal-Mart has no immediate plans to build supercentres in Japan following its recent move into the market via a stake in local retailer Seiyu. In an interview with CNBC Asia Pacific, Wal-Mart senior vice president Jay Fitzsimmons said: "I don't see us developing a separate set of stores. "We've got a relationship here and I think we'll focus on the relationship that we already have." Seiyu operates about 200 supermarkets and department stores in Japan, where Wal-Mart has spent months looking for the right entry vehicle. Last month it took a minority 6.1% stake in the company with the option to increase its share to 66%. Carrefour and Costco are already established in Japan and Tesco has had research teams there for almost two years searching for the right opportunity. {{NEWS }}
