Tōga's tomb

Inu no Taishō's tomb, also known as InuYasha's father's grave, is not really a grave at all, but rather the giant skeletal remains of Inu no Taishō. The gateway to his tomb is hidden in a black pearl, which was inside Inuyasha's eye, Inu no Taishōson by human woman named Izayoi. The location was kept hidden from his oldest, full demon son Sesshomaru, and at the beginning of the series, we are introduced to Sesshoumaru as he hunts for the location of his father's grave. The Tetsusaiga was kept here.

Inu no Taishō's tomb takes the form of an enormous dog-like skeleton with armor on the shoulders and on the chest. According to Myoga, this is his true form.
