In Kitamimaki-village more than 25 percent of the people are aged (more than 65 years old), and the percentage is speculated to increase from now on. Therefor, care prevention of the aged will become very important. Care prevention promotion plan was made focusing on the following two points. One is to continue taking data of health conditions of the aged in the village each year. The other is to prompt aggressively the use of care prevention programs designed according to health conditions and needs of each individual. In detail, first Good Walker's Index (Kenkyakudo) measurement will be measured along with the usual medical examination and everyday-life physical strength data will be recorded each year. Furthermore, healthy living guide and individual life-style improvement projects will be enriched along with intervention guide programs such as health improvement and rehabilitation programs (underwater exercise) using existing facilities as hot water pools. The expected outcome of this program is to clarify the effect upon the individual or the society and confirm its effectiveness and modify plans if necessary.
