Fast Retailing Co. launched its biggest Uniqlo flagship store yet Friday, aiming for it to rake in ¥10 billion a year in sales and reinforce the company's global competitiveness.

The massive store stands in Tokyo's Ginza district — "the best place in Japan, possibly the best in Asia" — as Fast Retailing President and CEO Tadashi Yanai put it during a news conference Thursday.

"Opening a global flagship store in this place is like making the first step on our plan to expand Uniqlo more in other Asian countries," Yanai said, adding that Asia is currently the hottest market.
