Benihisago

The is a giant gourd that was said to have once belonged to the Sage of the Six Paths himself, and has later come to be revered as one of the Five Ultimate Treasures. The item itself exhibits the unusual ability to "record" a person's soul in the form of words. After the words are first been drawn out by the Kōkinjō and then severed from the person's body by the Shichiseiken, the words will then be sucked into the container. Completing these conditions curses the afflicted individual, threatening to imprison them within the gourd if they were to utter their most frequently spoken word, which is inscribed directly onto the blade of Shichiseiken. There does appear to be some exceptions concerning the activation of the curse, but these have yet to be explained. However, as with the other four treasures, its usage consumes an enormous amount of chakra, so much so that any normal human would die after only a short period of time.

The gourd, along with three of the other treasures, was eventually gathered together by Kumogakure, where they came into the possession of the Gold and Silver Brothers. As the siblings possessed immense chakra reserves and later a portion of the Nine-Tailed Demon Fox's chakra, they alone were capable of wielding the treasures without fatal repercussions. Typically, Ginkaku would use the Kōkinjō in order to tie the gourd around his neck for the purposes of transportation. However, when in combat, this cord is removed, meaning that the large container must be held directly in hand.
