This summons forth a gate that is capable of blocking almost any attack; according to Sakon and Ukon, this is the ultimate defence developed by Orochimaru, and the fact that Kiba and Akamaru managed to dent it was impressive. It is believed that two people are required to summon it, however, Orochimaru was able to summon three of these gates by himself with his Summoning: Triple Rashōmon. To do so, he simply used both hands, instead of one, which is common in summoning.
This summoning appears to resemble a more demonic depiction of the main gate of old Kyōto.
This technique is used offensively in the games, summoning the gate directly beneath the target.
