Business sentiment in the Asia's second largest economy declined in the last three months of 2013 as the performance of Japan's economy weakened notably in the previous quarter, a survey published by the Ministry of Finance and the Cabinet Office revealed on Tuesday. The large-company sentiment index slipped from 12 points to 8.3 points in the Q3 and it is forecast to gain to 11.8 points in the Q1 of 2014.
