The episode has the first appearance of Moryoumaru.
Hakudoushi is supposed to tell Kohaku to go help Kanna, not Kagura. It was a mistake on the part of Hakudoushi's voice actor (Ai Kobayashi).
The Japanese title for this episode is Naraku wo Taosu Saidai no Tegakari, which means, The Best Clue to Defeat Naraku.
First aired on YTV (in Canada), November 17, 2006.
This episode is based on the events from chapter 335 to chapter 337 in volume 34 of the manga, and chapter 338 to 342 in volume 35.
Originally aired in Japan on September 6, 2004.
Inuyasha gang's encounter with Hakudoshi and Mouryoumaru was shortened. In the manga, this would have been the point of the series where Kouga makes a return since Mt. Hakurei.
