Japan's industrial output rose a seasonally adjusted 1.6 percent in June from the previous month, revised upward slightly from a preliminary 1.5 percent gain, the Ministry of Economy, Trade and Industry said Friday.

The index of production at mines and factories registered 101.2 against the base of 100 in 2000. Fresh data that indicate declines less severe than expected in output of steel ships mainly contributed to the upward revision, METI said.

The June shipment index grew 2.3 percent from May to 104.0, compared with an initially reported 2.0 percent rise shown in the preliminary report released July 29.

The inventory index shrank 0.2 percent from the May figure to 92.2, the same as the preliminary data.
