AirAsia Japan Co., one of the three Japanese low-cost carriers that started last year, is adding more overseas flights to increase foreign currency revenue to offset a rise in fuel and lease costs caused by a weaker yen.

"We're trying to balance the increase in costs with more inbound flights from overseas," AirAsia Japan CEO Yoshinori Odagiri said Wednesday.

AirAsia Japan, which flies from Tokyo's Narita and Nagoya's Chubu airports, will start daily flights to Taiwan next month and is considering adding another overseas service before the end of March, Odagiri said.
