Joshua Mainga was born and raised in Nairobi by an artist in a humble
farmer’s family. He got his interest for arts through his father the late John Ben Mainga who was famed for his leather and canvas batiks having exhibited in most Galleries across Europe, U.S.A and East Africa.

Having learnt the practice by observation and his involvement in his father’s work, he decided to take after his father in re-telling the numerous stories and folklore that he had heard from both his father and grandfather. He practised what his father had taught him and used it to tell the stories though his brush strokes and the use of colours on canvas using acrylics.

He participated in his first joint exhibition at the Kenya Museum while still in High School to try out his hand in arts. From the positive response that he received, Ihe decided to take on art as his career and since 2001, he has participated in various joint exhibitions at the Kenya Museums, Essajee Amijee Gallery, Braeburn School Art Fairs and RaMOMA and the Little Gallery.
