Gross domestic product for the July-September period contracted 0.6 percent from the previous quarter, Cabinet Office data showed, revising down the figure from the preliminary estimate of a 0.3-percent contraction.
The reading comes after growth of 0.7 percent in the April-June period.
The main driver of the decline appeared to be private investment, which shrank 2.8 percent quarter-on-quarter, compared with an initial estimate of a 0.2-percent contraction, the data showed.
