|This article is about a/an monster in Shuriken Sentai Ninninger.|
Created by Masakage Tsugomori when he infected a pair of track spikes with an infected Sealing Shuriken, Yamawarawa was made as his representative to challenge the three remaining Ninningers, Aka, Ki and StarNinger on a four-legged-race. Yamawarawa participated and cheated by switching the two Jukkarages with dummies, as well as Masakage unleashing traps but the Ninningers in the end won and released the other ninjas and their teammates from the Kibaoni Corps' captives. The Ninningers battled Yamawarawa and the Jukkarages with Aka and StarNinger killed Yamawarawa.
After Yamawarawa grown huge by Kyuemon Izayoi, the Ninningers summoned their OtomoNins to engage in a dogfight before other OtomoNins join and formed King Shurikenjin to destroy Yamawarawa.
Yamawarawa was among ten Yokai who appeared alongside Kyuemon Izayoi and the Western Yokai Wolf Man to Kinji in his vision after he had transformed into reincarnation of the Wolf Man, all bearing his face. When Kinji overcame his fear and doubt, and thus his Yokai side, he used the Demon Sword Urasame to vanquish all the illusionary Yokai and return to the real world.
While Yamawarawa has a high sport spirit, he lacks a code of honour and pulls dirty tactics, all to fulfil his own desire to win. He also has a habit of recording for every time of his activities (e.g. awakening, growing and death).
