The hottest summer on record in Japan has wilted sales of autumn merchandise at the Uniqlo casual clothing chain, its owner Fast Retailing said today (2 September).

Domestic same-store sales fell 9.3% in August, compared with the same month last year, while total sales (including online sales) were down by 2.2%.

“Due to high summer temperatures, fall item sales were sluggish, contributing to a year-on-year decline in same-store sales in August,” the company said in a statement.
