Tokyo River Friends was founded in early 2017 by members of Jambo International in order to focus on regular monthly clean ups of Tokyo area rivers, which was an expansion of several clean up events per year that Jambo had been doing for two decades as part of its broader environmental activities. We aim for people to experience the majesty of the rivers in and around Tokyo up close while engaging in productive and fun activities like regular river clean ups followed by picnics or barbecues along the rivers or Tokyo bay waterfronts. Our events will also be an opportunity for like-minded people to meet and make new friends. At the same time we will network with other group like Jambo, Kokusaika, and others for occasional joint events.
