Curbing growth in medical expenses and pensions is a constant battle for aging and heavily indebted Japan. But what lies ahead looks even trickier: creating a social security system that benefits all.

Promoted by Prime Minister Shinzo Abe, the idea is that Japan needs to remodel the existing system, seen as friendlier to the elderly, in favor of younger generations who bear responsibility for the country's future economic growth.

His recent push for stepping up investment in education for youth is largely seen as the right course of action. However, Japan will also have to deal with a significant demographic change in the near future and its subsequent impact on the social security system.
