This article seeks to illuminate the innovative contributions of Tosa nikki to the representation of travel in Heian Japan through a subtle blending of fact with fiction that employed poetic structures to mark space, time, and affect in its prose representation of the places segmenting its narrative. The diary’s placement in a liquid landscape far removed from the capital opens up a distinctive discursive space in which even the most banal sentences are deployed to great effect. Such aspects of the diary enable a greater appreciation of its longstanding significance as a new form of travel narrative, a dimension often overlooked in contemporary Anglophone accounts that focus on its connections to script and gender.
