McDonald's Holdings Co. (Japan) said Friday its third-quarter operating profit fell 19 percent to 1.73 billion yen because it spent more on training workers.

During the three months through Sept. 30, its sales increased 5.4 percent to 80.24 billion yen, despite the Olympic Games and a string of typhoons that kept people at home.

The hamburger chain's net profit for the period jumped 72 percent to 928 million yen, but the increase in year-on-year comparison was mostly due to hefty restructuring charges booked a year earlier.

The company has been revamping its operations under chief executive Eiko Harada since suffering two consecutive years of losses.

During a news conference to announce the results, Harada said the company has been making progress. Comparable store sales posted positive growth for four consecutive quarters, with the third quarter logging 4.9 percent growth, Harada said.
