Nintendo Co. jumped to the highest since August after buying a stake in Dwango Co., a company that provides content through mobile phones. The stock rose as much as 5.2 percent to 13,070 yen as of the 11:30 a.m. trading break in Tokyo. Dwango shares surged as much as 21 percent after the video game company bought 612,200 Dwango shares, according to a statement filed with the Tokyo Stock Exchange today. Nintendo isn’t planning to distribute games through Dwango’s video delivery system Niconico, Nintendo spokesman Yasuhiro Minagawa said. Nintendo currently promotes its games through the system, he said. ------ It could sound confusing for most people, but Dwango owns NicoNico video, which is esencialy Japan's Youtube. Now Nintendo is the 10th top shareholder for Dwango.
