The story
Akomase Festival in Mankessim area
An Akomase festival is documented in Ghana's Central Region as an annual pause for remembrance, when families tend ancestral shrines and pour libation before a modern durbar of chiefs and open dancing. Multiple traditional areas, including Gomoa Ajumako and, under a differently customed version, Winneba and Senya Beraku, hold their own observance under this name, and no source found ties the custom specifically to Mankessim as this listing suggests.
Akomase, a word used locally to mean a period of rest, names an annual custom observed by more than one Central Region traditional area rather than a single fixed event, and the clearest documentation available ties it to the Gomoa Ajumako Traditional Area.
