Nowdays many Korean citizen are joinning the no-buy Japanese product campaign.  
The campaign began after a South Korean supreme court ruling last year ordering Japanese companies to compensate Koreans forced to work in Japanese mines and factories when the Korean peninsula was a Japanese colony.
But Japanese Government insists that all compensation claims were settled by a postwar peace treaty. 
And the government have brought export restrictions on some valuable caemicals against Korean companies several month ago.
It makes Korean people more angry, and people voluntarily do not buy japanese product. 
Uniqlo, japanese retail company, has been very successful in Korea for a decade. 
Korean people has been targeted at Uniqlo.
