She never did anything particular to become popular in other countries (except for that trip to taiwn or wherever it was

) though. Her being famous in other countries is first of all because of Avex and because of the general popularity of japanese music, not her own effort. Perhaps if she continue to decline in the japanese industry, she could move to China

It's a potentially growing market at least.

The problem about the japanese scene seems to be that it's so fast so if an artist is on a break for some time from public activities, he or she is "gone".
