Summoning: Rashōmon

The user summons a large gate; Sakon and Ukon can only summon it together. The gate itself is designed to look frightening, with the gate's doors having a demonic face upon them; this is to intimidate onlookers, potentially warding them off. The gate's doors are tightly shut and solidly built, making it useful as a shield against most forms of physical attack. The stronger the attack, the more damage the attacker will do to themselves when they try and fail to break through the gate. Sakon and Ukon praise Kiba Inuzuka and Akamaru for being able to dent the gate, which they say is Orochimaru's strongest defence. Despite this, Orochimaru can also using a three gate variant, and beyond that is a five gate variant.

In the anime, this gate is shown to possesses offensive capabilities, with launchers installed in the roof-tiles that fire swarms of blades via a chain mechanism. However, launching too many of them near its base will cripple its foundation and the gate will collapse.

Trivia

 * The summoned Rashōmon is based off the main gate of old Kyōto with the demonic face inspired by the legend that Kyōto's Rashōmon was the home of an oni named Ibaraki-dōji.
 * In some Naruto video games, this technique is used offensively, the gate being summoned directly beneath the target. Some games depict the gate opening and dropping the target in another dimension.
