In Japan, elder education has been carried out not only in the sphere of welfare but also in the sphere of education. Elder education in the sphere of welfare focuses on education that promotes welfare, health, and hobby for elders while elder education in the sphere of education focuses on education needed for elders to play vital roles as important social members. Unlike Japan, elder education in Korea has been mainly carried out in the sphere of welfare. However, since Korea has been rapidly aged like Japan, and in particular, baby boomers begin to enter into the older generation group, there is a need to change elder education fundamentally so that baby boomers could have educational opportunities needed to play various roles as important social members. In this paper, in the premise that elder education in Korea should be carried out in the sphere of education, the author examines elder education that has been implemented in the sphere of education in Japan. In concrete, the auther explores how elder education has evolved from social education and lifelong education, why it is currently faced with difficulties, and what kind of efforts are made to overcome them. And based on this examination, the author attempts to draw some suggestions that Korean elder education might adopt to promote elder education in the sphere of education.
