To gather the idea and knowledge of Japanese Web people to come up with better solutions for Japan's current crisis, several major Japanese Web/Net players got together and organized "Hack for Japan" event. It is currently under way, 3/19-21. Participating companies provide hosting/cloud service, technical help and other resources, and participants can use any open software, including various Web APIs, Android/iPhone, Windows/Mac and so on. It is open to any developers for free.
