Abstract
This study aims to support academic writing by analyzing the use of metadiscourse markers (MDM) in the introductions of 10 humanities-related Japanese academic papers, with a focus on their relationship with rhetorical development. The findings show that different types of MDM are used across rhetorical moves. “Evidential” and “Transition marker” are common in establishing the research background, while “frame marker” are used to clarify research purposes. These results suggest that the appropriate use of MDMs is closely tied to logical development and supports effective academic writing.
