Tōga's tomb

, also known as the grave of Inuyasha and Sesshōmaru's father, and the grave of Towa, Setsuna and Moroha's grandfather, was not really a grave at all, but rather the giant skeletal remains of Tōga. The gateway to his tomb was hidden in the Black Pearl, which was inside of Inuyasha's eye.

The location was kept hidden from his oldest, full demon son Sesshōmaru, and at the beginning of the series, we were introduced to Sesshōmaru as he hunted for the location of his father's grave; the Tessaiga was kept here.

The tomb took the form of an enormous dog-like skeleton with armor on the shoulders and on the chest. According to Myōga, this was Tōga true form.

Travel
The tomb was on an alternate plane of existence from the world of the living, and thus could not be accessed in a traditional way such as by flight or on foot. All of the known entrances to the grave had quasi supernatural qualities. The original pathway was the original Black Pearl, a gem that acted as a direct gateway to the tomb, and it was placed within Inuyasha's eye. The other known methods of traveling to the grave were by entering the gate at the Realm of Fire, a feat which only Sesshōmaru was able to accomplish as the owner of Tenseiga, and get the way out from the Lake of the Staff of Two Heads. The other known method was concocted by Naraku. Tekkei, a demon associated with the, was beheaded, and the river of blood that flowed from her neck created a pathway to the tomb. Though this path opened and closed once the blood dried fairly quickly, also seemingly leaving Inuyasha and the group stranded. Also Tōga's third sword Sō'unga has a power to transport to the border and even open a gateway to the.
