Japanese TV reports how Korea is "learning" from Japan.
(it seems that it was aired on July 1st and that it is the same program that reported how China copied Disney Land.)
1) A Japanese staff tried to interview manufacturers. They rejected the interviews except one company on condition it answered anonymously;"It is not exact to say it is a copy;many companies produce a smilier whisky or a beer, it is like that."
2) There was a case Japanese company sued a Korean company---the Korean company won the case, because a Japanese company failed to register the trademark rights in Korea
3)A commenter noted that Japan used to imitates things abroad and ended with the comment to the effect that she hopes Korea would develop the products unique to Korea too.
