Kohaku no Jōhei

The is a large pot that had the ability to seal anyone within it, if the target responds when called by the wielder of the pot. If the person responds, the pot records their voice and then seals them. This function is similar to the Benihisago, but more advanced as less preparation is required. The pot has a stylised kanji for on it and a thick rope tied around its rim. It can even keep those brought back with Summoning: Impure World Reincarnation sealed after the summoner releases the technique. In the anime, it is filled with a dark liquid. The person that is sealed into the pot seemingly merges with the liquid.

The Kohaku no Jōhei is revered as one of the treasured tools of the Sage of the Six Paths. All five of the tools consume enormous amounts of chakra when used, so much so that normal humans would die after using the tools for only a short period of time. When the tools later came into the possession of Kumogakure, only the Gold and Silver Brothers — due to their large chakra reserves were able to wield the treasures without fatal repercussions. According to the A|Fourth Raikage, the pot was the only treasure that Kumogakure was able to wrest possession of from the brothers.

The Third Raikage used the pot to temporarily seal the Eight-Tails when its jinchūriki lost control of the beast. Darui would later use it in the Fourth Great Shinobi World War to seal Kinkaku. Tobi was later able to snatch the Kohaku no Jōhei from the Allied Shinobi Forces, and later allowed the Demonic Statue of the Outer Path to devour it, granting it the Nine-Tails' chakra from Kinkaku. After Madara Uchiha became the Shinju's jinchūriki, with both Gyūki and Kurama's Yang half fully instilled as part of the Shinju, he spat out both the Kohaku no Jōhei and Benihisago from his body, deeming them useless. They landed on top of Might Guy and Rock Lee. Tenten now keeps it within one of her scrolls, in hopes to use to use it against Madara Uchiha.
