The Tokyo Metropolitan Government established “Seaside park plan” and “Tokyo municipal seaside park ordinance.” The Tokyo Metropolitan Government considers that the conservation of seaside, riverside and urban parks make the creation of places where residents of Tokyo can come in contact with nature. However, it seems that the planning and construction of those parks have been carried out by the administration from one-side view. The waterfront parks are public and have been used by many people. As there have been no data what components of parks are important for users of parks, eight seaside parks called waterfront parks were watched, degrees of satisfactory of eighty two residents who live in metropolitan area about components of parks were surveyed, and degrees of concern about components of the parks have been obtained by conjoint analysis. Those waterfront parks are located at Odaiba near Tokyo Bay. Here, the components of parks are as follows; 1) Hydrophile, 2) Rest area, 3) Public transport and location, 4) Recreational facilities, 5) Scenery and appearance, 6) Maintenance, 7) Monuments, and 8) Openness. The following main results have been obtained from the research. : a) Both female and male consider scenery and appearance, and hydrophile are important. b) Rest area is the least important than other components to those in their 20’s, but important to those in their 30’s, 40’s and 60’s. c) Public transport and location are least important for teens, but important to all age groups. d) Those in their 50’s found 1) Hydrophile, 3) Public transport and location, and 5) Scenery and appearance are important. If there is an incomplete answer in response, we can utilize the data effectively by using the proposed method.
