In urban areas, there are many culverts (underground rivers) and inland flooding occurs easily around them. This study focuses on how development type of culverts influence on residents’ cognition of culverts and flood risk perception. Three areas were selected from Setagaya Ward with varying physical features, and questionnaire was distributed. Compared to road that is not a green road, culverts under green roads highly recognized as culverts. Although flood risk perception did not differ significantly between the areas, on an individual level, development type of culverts and interaction with them may influence on risk perception via cognition of culverts.
