The correct answer to this open question is the following.
Japan is dealing with economic concerns about an aging population in the following way. The Japanese government is inviting the seniors in Japan to not retire, instead, encouraging them to continue to work and be productive. Statistics show that 20 to 22% of Japan's population is seniors, older than 65 years. So that is why the Japanese government invites people to keep on being productive, generation some income for them, and extending the moment in which the government has to pay pensions.
