Nakatomi Sukekata (d. 1282) presided at Kasuga Wakamiya Shrine and brushed these three waka poems on a special type of paper used in poetry competitions. For his themes, Sukekata selected mist, Japanese bush warblers, and spring romance. The reverse side of the paper indicates it was once bound in a separate volume, as it bears traces of ink smudges.

A Shinto priest of the Kasuga Wakaymiya Shrine named Nakatomi Sukekata (d. 1282) has written three poems on the themes of mist (kasumi), Japanese bush warblers (uguisu), and spring romance. He writes in a natural hand on kaishi, a type of paper often used for writing poems at poetry parties. Later, something else was transcribed on its reverse; this writing bleeds through on the face of the manuscript.
