McDonald's Co. (Japan) plans to open more 24-hour outlets and raise the price of its main products, according to its business plan for fiscal 2006.

Eiko Harada, chairman and president of the hamburger chain, said in a news conference Wednesday the company will open about up to 200 24-hour shops nationwide by this summer to attract young customers.

The fast food chain already has several all-night restaurants. It wants to raise the number to about 900 over the next several years, Harada said.

He added that McDonald's will continue to adjust its low-price campaign and raise the price of its popular "value set," from 500 yen to 580 yen.

But the company plans to maintain the price of some items, including 100 yen hamburgers.

"We are pleased that we were able to increase the number of customers to the maximum level and improve the taste of our products and (quality of) service under our past strategies," Harada said. He said the company is considering starting a new restaurant business under the McDonald's brand name within this fiscal year.
