Though they are different species, Urnaconda and Yo-kai related to it might be inspired by the toubyou (トウビョウ), a youkai that migrated from China to the Shikoku island in Japan. They appear as small black snakes with a golden band around their neck, that can be tamed and kept in earthen pots, to call them forth when needed. They can be commanded to possess and curse someone, but they will turn against their master if mistreated. Toubyou are creatures that straddle the line between evil spirit and guardian deity, with ties to the ancient snake deities worshipped by pre-Yamato cults.
