Contemporary generic market in Japan – key conditions to successful evolution

The Japanese pharmaceutical market, the world's second largest, is traditionally renowned for the domination of patented drugs and the weakest generics share among major established economies. An in-depth observation of published evidence in Japanese/English language provided closer insight into current trends in Japanese domestic legislation and pharmaceutical market development. Recent governmental interventions have resulted in significant expansion of the generic medicines market size. Substantial savings due to generic substitution of patent-protected drugs have already been achieved and are likely to increase in future. Nationwide population aging threatening sustainable healthcare funding is contributing to the relevance of generic policy success. Serious long-term challenges to the modest Japanese generic manufacturing capacities will be posed by foreign pharmaceutical industries particularly the ones based in emerging BRIC economies.
