Japanese electrolytics are still cheaper than most polymer caps, and polymer caps aren't available in as high of capacitance/voltage as electrolytics are, for instance you can't get polymer caps that will work as primary caps for an ATX PSU.

In addition to the whole electrolyte formula fiasco, the Japanese caps are built to tighter tolerances than the Taiwanese and Chinese caps... Taiwan caps are built to higher standards than mainland Chinese caps, and many of the Chinese caps on the low end (Fuhjyyu, Canicon, ChengX) have false specifications (inflated capacitance, exaggerated ripple tolerance, etc.).
