TOKYO, July 20 (Reuters) - Japan's Nikkei share average dropped for the first time in seven days on Wednesday morning as Wall Street pulled back, hitting sentiment and triggering profit-taking from the recent gains.
Nintendo Co fell 10 percent in early trade after the stock more than doubled in value over the past seven sessions powered by the record-breaking success of the Pokemon GO mobile game.
Also under the spotlight was McDonald's Holdings Company Japan, which jumped 12.5 percent after TechCrunch reported the fast-food chain operator would become the game's first sponsor. TechCrunch said the sponsorship will see McDonald's 3,000-plus fast food restaurants across Japan become "gyms", or battlegrounds, for Pokemon collectors.
The Nikkei dropped 0.7 percent to 16,608.32 in mid-morning trade, after rising 10.7 percent in the past six days. Continuación...
