Industrial production in January was revised upward to a seasonally adjusted increase of 2 percent from the previous month, compared with a preliminary 1.5 percent rise, the Ministry of Economy, Trade and Industry said Friday.
The index of output at mines and factories came to 97.7 against the 1995 base of 100, up for the first time in five months.
The revision was due mainly to increased production in medicine and railway cars, it said.
The index of industrial shipments climbed 3.4 percent to 102.2, up from the earlier reported gain of 2.6 percent to 101.4, while the index of industrial inventories was left unchanged at an increase of 0.8 percent to 87.8 from a month earlier.
The factory operating ratio rose to 96.5 in January, up 1.4 percent from the previous month. It was the highest figure since the base of 100 was introduced in the survey, METI said.
The index for production capacity was 91.9, down an unadjusted 0.5 percent from December.
