An org to check out: People for Social Change

There comes a time in our lives where we feel that our lives are spiritual rich enough that a desire to 'give back' wells up inside. The challenge then comes in making a decision in which way can we give back. For some, there's always been sometime we've cared for: whether it's the environment or children. But for others finding that extra special cause can be challenging. One organization in Tokyo, People for Social Change, has taken on that challenge by organizing events to help people "move beyond issue awareness to actualize social change."

Once every two months, PSC holds workshops in which you can learn skills such as fundraising, letter writing and developing social justice lesson plans. Panel discussions and presentations are given by local NGOs.
So if you are looking to "give back" in 2007, perhaps attending an upcoming workshop or checking out their blog will give you some good ideas.
