Tōtōsai's house

Tōtōsai's house is on a volcanic mountain. The house itself is a skull of a giant unknown demon. It is where Tōtōsai lives and works as a swordsmith along with his flying ox Mō-Mō. Humans are unable to venture there due to the harsh conditions. Both Inuyasha (which he's a hanyō) and Sesshōmaru come here when they want help from Tōtōsai. Sesshōmaru uses the Meidō Zangetsuha as he had blasted a hole on the roof of Tōtōsai's home when Tōtōsai had put a "Moving" sign up when he knew he was looking for him after his encounter with Shishinki.
