As Japan faces the pressing issue of how to cover swelling social security costs amid an aging population, political parties are highlighting measures to reform the health care system for the elderly and the public pension system to ease the burden on the working generation.

The administration of former Prime Minister Fumio Kishida worked to establish an "all-age" social security system in which people, regardless of their age, bear burdens and support each other according to their abilities.

The Kishida administration drew up a reform roadmap late last year, including a plan to raise medical fees for elderly people who earn as much as the working generation.
