This paper considers the logic of the time expression "ato (after)" that is characteristic of the Uji chapters of The Tale of Genji. Following Hikaru Genji's death, the Uji chapters are imbued with reflections upon the past. I argue that this phrase often refers to death or times of unfavorable implications. It functions as an intensifier of the gloominess of the Uji chapters and uncovers their logic. For example, Hikaru Genji, the Eighth Prince (Hachinomiya), and Oi-gimi cast their shadows over the tale after their own death; Kaoru leads an empty existence after the burning down of his main residence, the Sanjo palace; Naka no Kimi is shown after her move from Uji to the capital, after her husband's marriage to Roku no Kimi, and as a figure she is marginalized within the tale after her birth of an imperial prince.
