In the last years of the 1980s, a new trend known as Magical Realism. emerged in Nigerian literature. I think that Ben Okri's "Worlds That Flourish" is one of the most typical examples written with Magical Realism. African people could become familiar with the novel of this new trend, because they could casily find their own mythological world that is deeply rooted in their souls. Through this Japanese translation, I would like to clarify that Social Realism, through which social comment can be caused, deepened into Magical Realism and through this, 'genuine' African literature was born.
