Prime Minister Shinzo Abe on May 17 announced a second set of economic growth policy measures. He aims to restore the private sector's total capital investment to ¥70 trillion a year (which prevailed before the Lehman Brothers shock of 2008), double farmers' income and agricultural and fishery exports, and carry out deregulation for particular companies that endeavor to create new technologies.

He must ensure that his plan doesn't fizzle out. The government must take a well-thought-out approach so that farmers and corporate executives are motivated to step up their activities.

In April, Mr. Abe announced a first set of growth measures centered on medical services and support for child-rearing households. He plans to announce a third set June 5.
