Torii Seal

After separating the Nine-Tailed Demon Fox's chakra from the beast itself, Naruto's seal changed into a more elaborate one, appearing on his Nine-Tails Chakra Mode cloak. Creating several torii by just touching his stomach and twisting his old seal, he was able to not only imprison the Nine-Tails, but also completely disintegrate a massive Tailed Beast Ball that it had created. Naruto then isolated the Nine-Tails' chakra in another part of him away from the beast itself in between three torii so he could access it freely. He can also enter the cage behind which the beast is sealed freely without breaking the seal as well as control the torii freely.

Influences
A is a traditional Japanese gate most commonly found at Buddhist temples and entrances of or within Shinto shrines, where it symbolically marks the entrance to a sacred area. Torii were traditionally made from wood or stone, but today they can be also made of reinforced concrete, copper, stainless steel, or other materials. They are usually either unpainted or painted vermilion with a black upper lintel.

Located in Kyoto, Fushimi Inari-taisha, which is the head shrine of the Shinto kami Inari, is very well known to hold thousands of such torii.

Trivia

 * When this seal was made, the Nine-Tails made an allusion to the Sage of the Six Paths in regards to the seal, but it actually never finished its statement.
