Revised data show Japan's economy expanded at a slower than hoped for 1.2 percent annual pace in the last quarter of 2016.

The figure released Wednesday was slightly higher than the preliminary estimate of 1.0 percent annual growth for the world's No. 3 economy. It was below economists' forecasts for growth of 1.4 percent or higher.

In quarterly terms, the economy expanded 0.3 percent in the October-December. The earlier estimate was 0.2 percent.
