Benihisago

The is a giant brown-coloured gourd with a red cloth around it. It is able to take a person's  hostage by saying the verbal command. After the word soul has been drawn out by the Kōkinjō and then severed from their body by the Shichiseiken, it is absorbed into the gourd. Completing these conditions "curses" the victim, if they utter the word they have said the most during their life, they will be sucked into and trapped within the Benihisago. Saying a homophone of their most frequently spoken word, or even saying nothing at all for a certain amount of time, will also trigger the gourd's suction. If a victim starts to be sucked into Benihisago, the suction will stop if their most-used word changes. Kurama noted that whatever was sucked into the gourd was sealed away and could not come out, no matter what. It can even keep those brought back with Summoning: Impure World Reincarnation sealed after the summoner releases the technique. Despite this, Darui managed to release Samui and Atsui after attaining the gourd, along with the Kōkinjō that was captured alongside its wielder.

The Benihisago 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. When not in use, Ginkaku used the Kōkinjō to tie the gourd around his neck for easier transportation. When the rope is removed for combat, he must carry the gourd.

Due to the Kōkinjō being sealed away in the Kohaku no Jōhei, the Benihisago has been rendered useless. Tobi later steals it and allows the Demonic Statue of the Outer Path to devour it in order to acquire the Nine-Tails' chakra from Ginkaku. After Madara Uchiha became the Ten-Tails' jinchūriki, with both Gyūki and Kurama's Yang half fully instilled as part of the Ten-Tails, he spat out both the Benihisago and Kohaku no Jōhei 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. After the Fourth Shinobi World War, Tenten placed the Benihisago, Kōkinjō and the Bashōsen on display place in her weapons shop.
