TOKYO, Jan. 31 (Xinhua) --Japan's industrial production rose a seasonally adjusted 2.5 percent in December 2012 from the previous month for the first rise in two months, according to the data released by the government Thursday.
The index of output at factories and mines stood at 88.9 against the base of 100 for 2005, the Ministry of Economy, Trade and Industry said in a preliminary report.
The Ministry of Economy, Trade and Industry said yen's weak in recent month is the main reason for the growth, which "shows signs of having bottomed out."
Japan's economy had experienced an extreme tough period amid the eurozone debt crisis and deteriorating relations with China over territorial disputes.
The index of industrial shipments rose 4.4 percent to 90.6 while that of inventories was down 1.1 percent to 105.2.
