Industrial output in December rose a seasonally adjusted 3.8 percent from the previous month, revised downward from a preliminary 4.0 percent rise, the government said Tuesday.
The Ministry of Economy, Trade and Industry attributed the downward revision to the addition of medical goods and liquor data, which were not available when it published the preliminary report Jan. 31.
The index of production at factories and mines stood at 93.4 against the base of 100 for 2005, marking the first rise in two months, METI said.
The index of industrial shipments increased 4.6 percent to 95.6, revised up from a 4.5 percent rise, and that of industrial inventories remained unchanged at 100.0, representing a drop of 2.9 percent from the previous month.
For all of 2011, production fell 3.5 percent to 91.1, unchanged from the preliminary report released Jan. 31.
