Gamespot is reporting that Japanese Airlines such as Japan Airlines and ANA have banned the use of wifi-capable game devices
, including the DS and PSP, over 'safety concerns'. From the article: "A law banning on gaming systems with wireless capabilities came into force on Monday, according to the Hollywood Reporter. Japan's transport ministry has concluded that the electromagnetic waves from the wireless networks can interfere with aircraft navigation systems, so it's no Nintendogs for passengers flying with Japanese airlines. The new law also bans wireless computer mice, and headphones that have not been provided by the airlines, although the use of electric razors, calculators, and cassette players is permitted, readers may be relieved to know."
