The word "exotic" seems to be interesting.
In the United States, it is used for Oriental things including Japanese style like the word referred to in the article.
On the other hand, in Japan, the English word is also used as Japanese word. But, its meaning is different from original one.
If you see Japanese citizen saying "Exotic", it means South East Asian, South Asian,or Middle Eastern style.
Though I don't know how the word became common in Japan, it might be used as the word meaing Oriental things except for ones which are familiar with Japanese.
So, to maintain the meaing of "foreign" and "Oriental", the word would have meant "South East Asian, South Asian,or Middle Eastern style".
