In this study, Japanese disability‐adjusted life expectancy (DALE) in two methods, was estimated to evaluate the possibilities of the indicator as a policy tool. It was specified that both methods had merits and demerits regarding data collection, calculation, accuracy, and significance. DALE is a summary measure of health outcome for policy evaluation and might be useful for turning policy makers’ eyes and capturing public awareness on health. The concept is appropriate and acceptable but more efforts are required to improve its quality and methodology. DALE is still a developing tool.
