A discount store owner, Yomiuri Tadashi Yanai, who runs the UniQlo chain, is one of the richest men in Japan.

Yanai is 31st on the annual list of the 100 wealthiest taxpayers in Japan, declaring more than 1bn yen in income.

He began with a store in Hiroshima in 1984 and now has 500 UniQlo stores across the country. The company's sales for the mid-year account period ending August last year reach about 220bn yen - 47.7 times as much as for the same period five years ago.
