  The Healthy Life Years Lost Methodology (HLYL) is introduced to model and
estimate the Health Expenditure in Japan in 2011. The HLYL theory and
estimation methods are presented in our books in the Springer Series on
Demographic Methods and Population Analysis vol. 45 and 46 titled: Exploring
the Health State of a Population by Dynamic Modeling Methods and Demography and
Health Issues: Population Aging, Mortality and Data Analysis. Special
applications appear in Chapters of these books as in The Health-Mortality
Approach in Estimating the Healthy Life Years Lost Compared to the Global
Burden of Disease Studies and Applications in World, USA and Japan and in
Estimation of the Healthy Life Expectancy in Italy Through a Simple Model Based
on Mortality Rate by Skiadas and Arezzo. Here further to present the main part
of the methodology with more details and illustrations, we develop and extend a
life table important to estimate the healthy life years lost along with the
fitting to the health expenditure in the related case. The application results
are quite promising and important to support decision makers and health
agencies with a powerful tool to improve the health expenditure allocation and
the future predictions.
