The global popularity of sushi, coupled with the yen's 18 percent decline in the past six months, is proving to be a sweet spot for Suzumo Machinery Co., Japan's biggest producer of automatic sushi-making machines.

The company plans to triple overseas sales to as many as 3,000 units from the last fiscal year and is boosting manufacturing capacity to meet demand in foreign markets, President Ikuya Oneda, 69, said Thursday.

"A weaker yen will make it easier for us to do business" abroad, Oneda said, adding that Suzumo may start taking payments in dollars, if customers request, as the Japanese currency weakens.
