The Japanese economy continues its resilient performance over the past three months since the devastating earthquake and tsunami in March according to the latest economic data released by the government.

On Friday, it was announced that the country had a 3.9 percent rise in factory output for the month of June, indication that growth has somehow cooled down following a sharp recovery in the aftermath of the twin natural disasters and subsequent nuclear crisis.

The increase in the June industrial output from the previous month is credited to the easing of pressures in the supply chain and the upward movement in household spending which rose by 0.8 percent.

In addition, retail sales also increased by 1.1 percent in the same month from the previous year after three consecutive months of dwindling sales when consumers shied away from stores during the months following the devastation.

In a survey conducted by the country’s economic ministry, most manufacturers are optimistic of the upcoming months as they anticipate a continued rise in output for July and August. The rise was actually slower compared to the median estimation of 4.5 percent and 6.2 percent increase in May.

After the disaster in March, Japan experienced massive disruption to its supply chain when several of its major manufacturers suspended or lowered production. As government quickly restored much of the damaged infrastructure, many manufacturers became increasingly optimistic and returned to normal productive levels.

Interestingly, the quick recovery in industrial output and supply chain came despite the many hurdles that manufacturers faced including power shortage.

The earthquake and tsunami four months ago damaged the Fukushima Daiichi nuclear power plant which led to the closure of many other nuclear plants throughout the country, leaving many industrial areas of the country to experience shortage in electricity.

Several companies have also released earnings for the first quarter of the 2011 fiscal year that ended in June where Softbank recorded a $1.21 billion profit while consumer company Toshiba posted a mild $6 million profit.

Meanwhile, a number of major consumer electronics companies including Sony, Nintendo, Panasonic, Sharp, and Fujitsu announced losses in their quarterly results. These companies attributed the disappointing numbers partly because of the March disaster and the challenges it brought to production.

On Friday, Japanese stocks fell because of the poor earnings report of several high profile companies as well as the continued impasse in the U.S. Congress on the debt limit. The Nikkei fell by 0.2 percent to 9,882.47 points while the Topix tumbled down to 846.08 points suffering a 0.3 percent fall.
