As Taiwan steps into an aging society, it faces problems of shortage of caregivers in aging society and an increased variety of care demands for elders, even those with serious disabilities. Considering Japan has similar cultural background as Taiwan, this study attempted to introduce an assistive technology rental system in Japan, where long-term care insurance and a rental service of assistive technology has been implemented since 2000. The use of assistive technology could reduce the caregivers' burden, and help elders to become more independent and active. As a result, Japan, the first aging country in the world, is able to reduce the waste of medical resources for the end of life.
