Japanese producer prices rose more than forecast, driven by higher commodity costs and supply constraints of oil after last month's record earthquake threatened to push up prices of some raw materials.

On the other hand, the PPI index rose 2.0% during the year ended March, from 1.7% a year earlier, while the analysts' forecasts estimated of 1.9%. Further, monthly reading jumped by 0.6% in March compared with a previous 0.2% in February, where the expectations referred to 0.4%.
