Pokemon Go will launch in Japan today, the Wall Street Journal reported yesterday on its digital edition.
Burger chain McDonald's will take part in the launch by making its restaurants key places for Pokemon players.
Meanwhile it looks as if Pikachu might have been single-handedly holding up Japan's stockmarket.
Shares for Nintendo, the company behind Pokemon have been soaring recently but dropped 8 per cent this morning. The Nikkei also dropped for the first time since Pokemon's launch.
But, on this morning's news, McDonald's shares have risen.
