While a South Korean consumer boycott of Japanese products continues in the wake of a prolonged dispute over wartime history and trade, economists say Japan has already seen the worst of its economic repercussions.

Concerns had grown among businesses as moves to shun Japanese brands quickly spread, and cancellations of flights from South Korea to Japan increased in number.

Among Japanese firms operating in South Korea, Fast Retailing Co.'s Uniqlo casual clothing chain became one of the biggest targets of the boycott.
