The Kyoto-based company behind the Super Mario franchise and the Wii console said Monday its net profit for the fiscal year ended March 31 fell 66 percent to 77.6 billion yen ($947 million) from 228.6 billion yen the year before.

Nintendo, which does not break down quarterly numbers, said annual sales slipped 29 percent to 1.014 trillion yen ($12.4 billion).

The company expects conditions to improve gradually over the next year, with sales of its new 3-D handheld game machine, the 3DS, offsetting an anticipated decline in Japanese consumer spending following last month’s earthquake and tsunami.

“Nintendo has not suffered any direct damage which will significantly affect our production. However, it can be predicted that there will be an indirect impact from individual consumption patterns,” the company said.

It forecasts sales to rise 8.4 percent to 1.1 trillion yen ($13.4 billion) for the fiscal year through March 2012 and expects earnings to increase 41.7 percent to 110 billion yen ($1.34 billion).
