Uniqlo owner Fast Retailing said sales and operating income for the year to the end of August both rose in double digits thanks to a strong international performance.

The Japan-based business said net sales for Uniqlo Japan rose 12.5% in the year to JPY605.5bn, thanks to strong sales in the first half offset by a weaker performance in the second six months. Meanwhile, operating profit was up 17% to JPY129.5bn.

Uniqlo International nearly doubled its sales over the same period, with operating income surging up 293%, Fast Retailing said.

The company blamed unseasonably cool temperatures in early spring and a delayed demand for autumn clothing for its poor second half of trading in Japan.
