TOKYO -- Tadashi Yanai turns up to the interview in his Uniqlo mask and a cardigan over a button-down shirt, striding into his Tokyo office meeting room. The wall is decorated with an intricate world map and a framed piece of Japanese calligraphy that reads: "world's number one."
Ranked as Japan's richest man by Forbes, Yanai could probably afford more expensive clothes than those he is wearing. But he has made his fortune as an evangelist for casual wear. Today, it is almost impossible to find anyone in his native country who has never shopped in Uniqlo.
