In Haruki Murakami's "1Q84," the author references Chekhov's principle regarding the use of elements in storytelling. Tamaru emphasizes that if a gun is introduced in a narrative, it must be used, highlighting the necessity of relevance and purpose in storytelling. This idea discourages the inclusion of superfluous items that do not contribute to the development of the plot or characters.

Chekhov's approach advocates for a streamlined narrative, where each element serves a function. By eliminating unnecessary details, the storytelling becomes more focused and engaging, allowing readers to connect more meaningfully with the unfolding events. Murakami's acknowledgment of this principle underscores its significance in crafting compelling and purposeful prose.
