McDonald's Co. (Japan) said Thursday it will introduce two health-conscious pita bread sandwiches at its outlets nationwide in a three-week campaign beginning Aug. 4.

Seeing June sales rise 11.6 percent from the same month a year ago due to raising the price of its popular "value set" in May, the Japanese unit of the world's largest fast-food chain expects to extend its business recovery by introducing the new items, it said.

The company will sell a pita bread sandwich with lettuce and spicy tandoori chicken topped with sour cream for 270 yen, and one with an extra slice of tomato for 290 yen, it said.

The special food items will be available until Aug. 24 but may be added to the regular menu if they prove popular, it said.

"The (sales increase) outcome is due to support from our customers," said Eikoh Harada, chairman and president of the company.
