Japan's industrial output in May grew a seasonally adjusted 1.9 percent from the previous month, revised slightly downward from the initially reported 2.0 percent rise, the Ministry of Economy, Trade and Industry said Friday.
The reading represents the fourth consecutive month of growth, in a sign that production is picking up.
Data on components for aircraft, which were not available when the preliminary report was issued June 28, contributed to the downward revision, a ministry official said.
The index of output at factories and mines came to 97.7 against the base of 100 for 2010.
The index of industrial shipments was revised upward, posting a growth rate of 1.0 percent against an initially reported rise of 0.8 percent. The industrial inventories index was down 0.4 percent, against a preliminary 0.3 percent decline.
