Expectations are growing that Japan will finally achieve a full-scale economic recovery this year.

The current one is Japan's third recovery since the collapse of the bubble economy in the early 1990s. But this one differs from the previous two in that it is being led by the private sectors, including the corporate sector.

Japan has posted an average growth of 1.5 percent since the ongoing upturn began in the January to March period, with domestic private-sector demand expanding 0.9 percent and overseas demand 0.7 percent. Meanwhile, domestic public-sector demand fell 0.2 percent.
