Nintendo Co's shares fell 10 percent in early trade on Wednesday after they more than doubled in value over the past seven sessions powered by the record-breaking success of the Pokemon Go mobile game.

As of Tuesday's close, Nintendo had added $23 billion to its market capitalisation in heavy trade since the July 6 launch of the game in the United States, Australia and New Zealand.

But later it reported that there were concerns among the companies that the hype generated would overload the game. It added that it wasn't immediately clear when the game would be released in Japan.

Pokemon Company, which created the game along with Nintendo and Google-spinoff Niantic, could not immediately be reached for comment. Nintendo has referred any queries regarding Pokemon Go to Pokemon Company.

Pokemon Go is on its way to becoming the first mobile game to break the $4 billion-per-year wall, beating Candy Crush Saga and Supercell's Clash of Clans, according to Macquarie Research.

Shares of Japan's McDonald's Holdings Co piggy-backed the Pokemon Go craze, rising 12.5 percent in early trade 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.

McDonald's Japan shares soared as much as 23 percent to their highest level since late 2001 on Tuesday, the first day of trade since its stores started giving away Pokemon-themed toys with its Happy Meals last Friday.
