Since the massive earthquake, the global community has been responding quickly - from NGOs to celebrities.
Local and international NGOs are sending relief and support teams to Japan, where they are assessing needs and setting up emergency plans.
On the internet, Google has put up the People Finder platform (japan.person-finder.appspot.com). The website allows anyone to search and post information on people affected by the disaster.
PayPal CEO Judy Chang announced that from now until April 10, the company will credit transaction fees to American and Canadian registered charities that are raising funds for Japan.
Several celebrities have also been quick to respond. Justin Bieber, Taylor Swift, Adam Lambert and many others have offered their condolences and words of support via Twitter. Lady Gaga designed a 'We Pray For Japan' wristband, which sells for US$5 at her official website's online shop. All benefits go to relief aid in Japan.
South Korean television and pop stars, who are very popular in Japan, have donated millions of won to the quake and tsunami victims. Kim Hyun-joong, a member of the popular South Korean boy band SS501, and actors Ryu Si-won and Song Seung Hun have also made donations.
