* Upgrades FY op forecast to Y16.5 bln from Y15 bln previously
* H1 profit Y9.4 bln vs Y47 mln year earlier
* 19 months of double digit same store sales growth (Adds full year sales figures)
TOKYO, Aug 9 (Reuters) - McDonald's Holdings Co Japan Ltd upgraded its full year profit outlook on Wednesday as the fast-food chain sustained a recovery from a series of food scandals that hit consumer appetites.
The company, an affiliate of U.S. fast-food giant McDonald's Corp, forecast full year operating profit to be 16.5 billion yen ($150.05 million) for the year ending December, compared to an earlier forecast of 15 billion yen and up 138 percent on the previous year.
Operating profit in the six months through June was 9.4 billion yen. That compared with a 47 million yen operating profit a year earlier.
Same store sales have grown in double digits for the last 19 straight months with consumers lured to stores by a revolving array of time limited items including Hawaiian-themed loco moco burgers, the chocolate banana flavored Pikachu McFlurry and Pokemon-themed Happy Meals.
The fast food chain was rocked by a series of safety scandals dating back to July 2014, when a major Chinese supplier of chicken was accused of food-safety violations.
The scandals saw the company slump to two years of operating losses before returning to profit in the year ending last December.
