Japan's largest business lobby stressed on Tuesday the importance of structural reforms while pushing for actors in the political and corporate spheres to drive the innovation they say will help overcome the nation's labor and productivity challenges.

In his new-year message, Hiroaki Nakanishi, chairman of Keidanren, said the organization will continue promoting greater use of new digital technologies. It also wants closer cooperation between business, government and academia to resolve the social challenges the organization's strategy outlines as barriers to growth.

In addition to such growth measures, "encouraging structural reforms including making the social security system sustainable and accelerating fiscal rehabilitation while maintaining the international economic order will be the main pillar of our lobbying activities," Nakanishi said.
