volunteer

Today I was looking for something volunteer group in Kumamoto and I found a group which name is "Green Bird". This group seems to picking up garbage. I wanted to do like this group and I have been looking for a volunteer group like green bird. I want to join it but I don't know how do I join it. In addition, I don't have any courage to join it by myself only. I want to join it with my friends but they look so busy. I will ask them tomorrow. I want to do something and I hate that do not anything until graduate. I hope some friends say "I'll do it with you." Does anyone do it together ??
