Japanese art covers a wide range of art styles and media, including ancient pottery, sculpture, ink painting and calligraphy on silk and paper, ukiyo-e paintings and woodblock prints, ceramics, and origami. There's many different types of japanese art styles but a perfect example of japanese art is "The Great Wave off Kanagawa" by Katsushika Hokusai (I've attached it below)

African art describes the modern and historical paintings, sculptures, and other visual culture from native or indigenous Africans and the African continent. The African art is of course of another culture, but is unique to its culture. A great example of african art is the painting I attached below.

For the assignment they assigned you, I am assuming they want you to draw/paint something inspired by both of these cultures. Take a look at these examples and see if it sparks your creativity.. GOOD LUCK ! :)
