|This article is about a/an monster in Shuriken Sentai Ninninger.|
Yokai Kamaitachi was created when one of the corrupted Sealing Shuriken was imbedded into a discarded chainsaw following Gengetsu Kibaoni's revival and a onslaught of Hitokarage appeared in the city. Following Takaharu's resolve to fight the Kibaoni after doing a brief battle against Kamaitachi, the other Ninningers suited up and fought Kamaitachi and his entourage of Hitokarage, eventually ending with Kamaitachi being defeated by AkaNinger's Ninja Violent Slash.
Following his defeat however, Kyuemon Izayoi revived Kamaitachi, allowing him to send the taken-aback Ninningers flying with a swing of his claws. However, the Ninningers soon summoned their OtomoNin mechs and began taking the fight back to Kamaitachi, starting with AkaNinger and Shinobimaru.
When Kamaitachi unveiled his lastest toy in the form of throwing kunai at Shinobimaru, the OtomoNin blocked them with a revolving street-sized panel, and when it flipped back down, it revealed KiNinger and Dumpmaru who then threw exploding caltrops at Kamaitachi's feet. With ShiroNinger and Wanmaru proving difficult to work together with even with MomoNinger and Byunmaru's help by unhelpfully sitting down or catching Byunmaru's multiple shuriken, Shinobimaru appeared behind Kamaitachi via a revolving buildingside and gave him a solid whack upside the head with a piece of steel scaffolding. When he tripped, however, Kamaitachi was on him in a flash, slashing Shinobimaru up onto his feet and pinned him to a building side.
Quick to the rescue, Dragomaru and AoNinger arrived with a blast of flame to get Kamaitachi off of Shinobimaru, allowing the Ninningers space to form Shurikenjin. Once completed, Yokai and mech duked it out, ending with the destruction of Kamaitachi and the purification of the Sealing Shuriken that spawned him.
Kamaitachi and a legion of Hitokarage were used as virtual enemies by the Ninningers in a team training simulation in their Dojo. However, AkaNinger had ignored the "team" part of the training exercise, and laid waste to the virtual forces with a Super Ninja Violent Slash.
Kamaitachi was among the Yokai the Igasaki Ninningers noted to Kinji Takigawa they had destroyed prior to his arrival, making him displeased that he didn't have the chance to defeat them personally as StarNinger.
Kamaitachi was part of a group of 100 revived Yokai that appeared on the day of Hyakki Yakou and were fought by AkaNinger and StarNinger. During the contest between the two Ninningers to defeat the most Yokai, Kamaitachi was destroyed by StarNinger but not before the Ninninger made sure to take a selfie with the Yokai.

Behind the Scenes
- Yokai Kamaitachi's suit actor is Keizo Yabe.
- Yokai Kamaitachi's act of cornering OtomoNin Shinobimaru to a building is a reference to the Japanese meme "Kabe-Don" (壁ドン? lit. Wall Block), where a man cornered a woman in a romantic manner, though now commonly called "Semi-Don" (蝉ドン? lit. "Cicada Block").
- Kamaitachi's habit of yelling "Che ha ha!" is a reference to the sounds of chainsaw, which is also used as a recurring sound effect in the Friday the 13th film series. In another reference to the horror franchise, Kamaitachi's face somewhat resembles a hockey mask, a homage to Jason Voorhes.
- Elements from this costume would be reused in Yokai Otoroshi.
