The purpose of this thesis is to analyse unreliable narration and its motivation in the two novels by Kazuo Ishiguro, An Artist of the Floating World (1986) and The Remains of the Day (1989) using the taxonomy of Zuzana Fonioková and James Phelan and Mary Patricia Martin. In its theoretical part, this thesis explores the concept of unreliability in contemporary narratology, furthermore, it studies self-deception and memory, two phenomena essential for understanding the motivations for unreliable narration. The practical part consists of an analysis of the textual signals of unreliability, which proves the complexity of Ishiguro's narrative strategies. The thesis concludes that the climax of both the novels is created through the spelling out of the narrators' self-deception, which is the cause of their unreliability in the first place.
