Respect-for-the-Aged Day (敬老の日, Keirō no hi) is a Japanese holiday celebrated annually to honor elderly citizens. A national holiday since 1966, this used to be held on September 15. Beginning in 2003, Respect for the Aged Day is held on the third Monday of September.
This national holiday traces its origins to 1947, when Nomatanimura (now Yachiyocho), Hyōgo Prefecture proclaimed September 15 Old Folks’ Day (Toshiyori no Hi). Its popularity spread nationwide, and in 1966 it took its present name and status. Annually, Japanese media take the opportunity to feature the elderly, reporting on the population and highlighting the oldest people in the country.(Wiki)
