Prime Minister Shinzo Abe will tout a rare growth plan next week that sets a numerical target for private capital investment over the next three years.

While Abe's team has been steadily issuing grand announcements, it hasn't put much economic legislation on the table and is waiting until just before the election in July to release its official economic plans.

In his latest proposal, due out Friday, the government is looking to increase private-sector investment 10 percent over the next three years until it reaches about ¥70 trillion a year, or about the same level Japan was at before the global financial crisis struck in 2008, government officials said Saturday.
