A chance to do something good, meet new people, and have a great day out in Tokyo. What happens? Tokyo River Friends organizes regular litter-picking events on the banks of the Arakawa and Edogawa rivers. As well as helping the environment, participants can enjoy a guided eco-walk experience along the riverside, learning about the wildlife on the water's edge. No reservation required -- just show up at the appointed meeting spot. The organizer will lead everyone to the site together so be on time. After a few hours of work, participants usually head out for a picnic or meal at a local restaurant.
