Yanari (家鳴り Yanari, lit. House Squeaker) are miniature to human-sized oni yōkai.
In the 2007 anime, they don't speak normally, instead make chattering noises, and Kyūso can understand their sayings. They also don't usually squeak buildings unless they are interested in or are entertained, or being threatened.
A trio of Yanari appear in episode #92 of the third anime adaptation, The Man-Eating House and Yōkai Yanari.
Multiple Yanari appear in episode #72 of the 5th anime adaptation, Yōkai Castle Awakens!! Shu-no-Bon's Difficult War Story.
