Urban waterside is drawing attention as valuable open space and being discussed on its utilization for creating more attractive city. Among these, rowing activities, such as Stand Up Paddle boarding (SUP) is considered to have potential, but the relationship between these activities and urban waterside has not been discussed. The purpose of this research is to understand the situation of urban kayaking and SUP activities through the case studies of 4 groups and questionnaire survey for kayak and SUP users in order to find out the impact on raising awareness of participants . As a result, it became evident that urban kayaking and SUP activity groups provide safe access for people from kids to elderly to the urban rivers through establishing relationships with stakeholders such as local communities and governments. Besides, people participated in the urban rowing activity have raised their awareness to the river environment or local contribution, and some of them started to support these activities. In order to accelerate this positive cycle, public sector is expected to assemble information such as access points, safety guidance and activity groups while increasing access points through delegating the management of the access points/piers to activity groups.
