Nintendo, Sony, Namco, CCP, Zynga, Sports Interactive and others have pledged millions to Japan’s earthquake aid effort after last week’s natural disaster.

Following news yesterday that platform holders Nintendo and Sony have both contributed ¥300 million (£2.3 million) to relief efforts, EVE Online developer CCP said today it's to offer PLEX donations from the game as charitable incentives from its MMO.

Simply known as PLEX for Good, the program launched yesterday and will continue to run until March 31. More info on the drive can be found through here.

CCP said that PLEX donations made from EVE will be converted into real currency and donated to the Red Cross for its relief operations in the country.

Sony Corporation has also donated 30,000 radios to aid efforts.

On the publisher side, 5pb and Namco Bandai have also contributed.

Japanese news-based site Siliconera is also holding its own fundraiser here.

In addition, Game Informer writer Meagan Marie is auctioning off a rare one-of-a-kind Nintendo DS unit to promote Mario Kart DS.

It's been signed by Shigeru Miyamoto, Mario and Zelda composer Koji Kondo, Zelda producer Eiji Aonuma, Mario voice-actor Charles Martinet and Martin Leung, a pianist who famously played the Mario theme blindfolded.

The auction's here.

In the west, Zynga has teamed up with Save the Children to raise relief money for aid operations from micro-transactions bought in-game from its games such as CityVille, Farmville and Frontierville.

Sports Interactive had also announced a charity initiative to help victims of the earthquake. The studio has promised to donate all of its revenue from the iOS version of Football Manager Handheld 2011 to a disaster relief fund in Japan for seven days, beginning last Friday.

Local activity hit

Help from the games trade comes after Square Enix and Konami confirmed said yesterday that they were shutting down servers for Final Fantasy XI, XIV and Metal Gear Online to conserve energy, following two explosions at one of the country's nuclear power plants.

The situation at the Fukushima plant has now worsened, as is being widely reported.

A series of promotional events for games in Japan had also been cancelled, including Yakuza of the End, BlazBlue Continuum Shift II, Dead or Alive Dimensions and the Monster Hunter Festa.

Delays have also been been announced, with Motorstorm Apocalypse and Yakuza of the End both pushed back, with PS3 survival title Disaster Report 4 canned outright.

Microsoft's held back Xbox Live-related products as well as announcing a delay to the Japanese release of Dragon Age: Origins expansion Awakening. It's also cancelled a national tour for Kinect.

Sony has put on hold its PlayStation information and repair centers, a report from Andriasang claims.

Sony will keep PlayStation Network open in Japan, but insists that connectivity to the service will be difficult to access in some cases. The report also says that some content updates will most likely be delayed.
