In Japan, health care services provided by the long-term care insurance system takes costs depending on the health care level. Although the system has been revised several times, such revision made the system more complex, so that a web-based system by which every people can accurately and easily ask about the long-term care insurance system is needed. Thus, the proposed interface in this paper has two points to achieve the requirement. First point is to show only basic information related to selected options on the web page. The second point is that dependencies (parent-child) among each category for inquiring should be presented on the web page to make the user understand each ranges of the category meaning. The experimental evaluation shows that our proposed presentation method using the web interface has advantage on perception among categories, human error, and user-friendliness.
