Industrial output rose a seasonally adjusted 2.3 percent in June from May instead of the previously reported 1.9 percent, the Ministry of Economy, Trade and Industry said in a revision Monday.

The index of output at factories and mines stood at 96.9 against the base of 100 for 2000, compared with 96.5 in the preliminary report, the ministry said.

The upward revision in the June data was prompted by increases in output of aircraft engine parts and plastic parts for machinery and appliances, METI said.

Industrial shipments were also revised upward to a 1.7 percent gain instead of 1.2 percent in the preliminary report, while inventories remained flat compared with the previous month.
