Takaharu Igasaki (伊賀崎 天晴 Igasaki Takaharu) is AkaNinger (アカニンジャー Aka Ninjā, Red Ninja), who is also known as The Fiery Ninja (熱い忍者 Atsui Ninja), the Red Ranger of the Ninningers. He is the older brother of Fuuka Igasaki. He is called as Brother Taka (タカ兄 Taka-ni) by Yakumo and Taka-chan (タカちゃん) by Nagi.


One of Yoshitaka Igasaki's successors, Takaharu was one of his grandchildren chosen to become the Ninninger, even the first one to use its powers. While on his way to his family's dojo, an army of Hitokarage destroyed it, with Takaharu transformed for the first time as AkaNinger and eliminate them. After reuniting with the other Ninninger candidates, Tsumuji Igasaki, his father leads them to Gengetsu Kibaoni's resting place, which was sealed by Yoshitaka until the Sealing Shuriken were released by the revived Gengetsu and wandered off to various part of the city. After the Ninningers destroy Youkai Kamaitachi, it grew large and they received five OtominNin Shuriken, which they used to form Shurikenjin and finished the Youkai. Yoshitaka revealed himself to be much alive, but lectured them for their inexperience and lead them to the new dojo that they will use as their new base. Shinobi 1: We're Ninja!

Over time, Takaharu becomes his team's leader, as they face many more Youkai and tried to reclaim their grandfather's 48 Sealing Shuriken while trying to inherit the Last Ninja title.

Alerted to a Youkai appearance, the Ninningers discovered only a Sealing Shuriken found by Fuuka, realizing that someone else was now fighting the Yokai. Following this, it was revealed that Yakumo's mother, fashion designer Harukaze Katou, had the End Shuriken as an accessory on a designer dress she made for her new fashion show in Japan. The Ninningers then enacted their plan to recover the End Shuriken and swap it with a fake, with Takaharu and Yakumo heading onwards as the others aided them through disguises. However, matters were complicated as the Kibaoni Army moved to take the End Shuriken themselves, sending the magic Youkai Ittan-momen and the new Jukkarage grunts. His first act was to use a transformation spell to turn Fuuka into a mouse, with Kasumi seemingly following, leading Takaharu to house them in a mouse cage. Nagi was then turned into a rock before the Ninningers caught up with the End Shuriken, with Yakumo being the last one standing when Takaharu was turned into a doll. However, he was able to outsmart Ittan-momen with a combination of magic and Ninpou as Kasumi, having used a decoy, acquired the End Shuriken. Fuuka and the others were then changed back to normal when Yakumo used a reverse spell against Ittan-momen. The Ninningers found that the End Shuriken was a fake all along when Kyuemon attempted to take it before receiving unexpected aid from a sixth Ninninger with his own OtomoNin in the giant battle. Shinobi 9: Ninjutsu vs. Magic, the Great Battle!

During the hottest point in summer, the boys decided to play a prank on the girls after Nagi overheard Kasumi confide in Fuuka that she was afraid of ghosts. Luring the two to an abandoned building which they claimed to be haunted possibly due to a Yokai, they proceeded to put on spooky costumes, with Takaharu dressing as a red pepper. Pulling their prank, they were confused to see only a spooked Fuuka run out, especially due to her claiming to see a 'lady ghost' which they did not account for. Takaharu headed back for Kasumi, followed by Yakumo and Kinji. With no word, Nagi and Fuuka found they had been frozen by the Yokai Yuki-Onna, with Fuuka soon following suit. Left alone, Nagi managed to conjure some heat as Kasumi revealed herself having used a decoy, luring the Yokai into a trap. Takaharu and the others were thawed by a Fire technique as the Ninningers proceeded to defeat Yuki-Onna. Shinobi 23: It's Summer! Ninja Courage Test

Takaharu finds that he has come last place in the mid-point Last Ninja race.

When Yoshitaka announced the mid-point results of the Last Ninja race, Takaharu was devastated to learn that he made the last place at 6th. In reality, however, "grandad" was actually Nekomata's doppelganger Yokai Mataneko in disguise, who intended to get revenge against the Ninningers by breaking them up, hosting a lightning quiz round when the initial results failed. After the Ninningers noticed signs that something was amiss, Kasumi fetched a second Yoshitaka, exposing the first as a fake via catnip. The Ninningers then transformed to fight him, with Takaharu as AkaNininger Chozetsu defeating Mataneko with Shinobimaru after being accidentally enlarged alongside the Yokai. Afterward, at the request of his grandchildren, Yoshitaka gave his true mid-point results, stating that they were all still at the starting line, with this news only giving them a strengthened resolve to continue training. Shinobi 26: It's Summer! Last Ninja Race Intermediate Announcement!

Beyond AkaNinger, Takaharu valiantly opposed Sakuya Kyuemon single-handed, attempting to get through to the fellow student of his grandfather before his teammates joined with him to back him up. With their unwavering resolve, all six Ninningers were able to restore their Nintality, transforming together and overcoming Sakuya Kyuemon, managing to get through to him before he was absorbed by Gengetsu who, as a giant, would be finally destroyed by the Ninningers in Gekiatsu Dai-Oh with help from Kyuemon, who left behind the End Shuriken before passing away. With the End Shuriken in their grasp, the Ninningers used it to wish for a world without the End Shuriken, finally wiping out the Yokai and restoring the damage that had been done to the world. With the title of Last Ninja passed onto them, the six Ninningers elected to go their separate ways and meet back in two years to recollect what they have each done.

Naming himself the New Last Ninja, Takaharu opened his own school of ninjutsu where he would teach a new generation of ninja. Shinobi Final Chapter: To a Future Without Hiding, Wasshoi!

Takaharu is the type that acts before thinking. He acts like a big brother, trying to pull everyone together, sometimes unsuccessfully. His caring nature makes him draw the shortest straw most of the time, but even then, he is an optimist who believes everything will be alright.

As one of the successors of Yoshitaka Igasaki, their grandfather and the Last Ninja, Takaharu always looked up to him and admires his skills. Takaharu also wanted to inherit the Last Ninja title and would lecture anyone that tarnishes his grandfather's pride. While Takaharu has a bad performance in ninja techniques when training, he is eventually able to master it quickly if he is in a real battle, something that is noted by Yakumo and his Red Sentai Ninja predecessors.

In episode 17, Takaharu is revealed to have a fear of peppers. Why he has this fear isn't explained in the episode, especially considering that, as Kasumi reminds him, he really likes pepper steak.

At the end of the Last Ninja Race, Takaharu is the only one whose remarks from Yoshitaka are vague. However, Yoshitaka telling him to "become the strongest ninja in the world" does suggest that he still dwarves the other Ninningers in raw power.

The AkaNinger Ranger Key (アカニンジャーレンジャーキー Aka Ninjā Renjā Kī) is Takaharu's personal Ranger Key released as part of a set of Ninninger Ranger Keys in Premium Bandai. The AkaNinger Ranger Key was mainly used by Captain Marvelous (Gokai Red), who used it to fight as AkaNinger.

Behind the scenes


Takaharu Igasaki was played by Shunsuke Nishikawa (西川 俊介 Nishikawa Shunsuke). As a child, Takaharu is portrayed by Kento Kusumi (久住 健斗 Kusumi Kento). As AkaNinger, his suit actor is Yugo Fujii in the first 7 episodes and Kosuke Asai from episode 8 onwards.


Takaharu's family name, the Igasaki is a reference to an intermediate-ranking Iga ninja of the Sengoku Period, Tateoka Doshun, whom also known by the name Igasaki Doshun (伊賀崎道順).


  • Unlike the other Ninningers, AkaNinger's helmet design is of a shuriken in 'mid-motion' or 'spinning' and is not symmetrical.
  • He is the only Red ninja Sentai Ranger whose first name does not contain the "-suke" suffix in it.
    • However, his actor, Shunsuke Nishikawa, does.
    • Humorously, so does the first Kamen Rider the Ninningers share the Super Hero Time lineup with, Shinnosuke TomariIcon-crosswiki.png (Kamen Rider Drive), whose primary form is red-colored.
    • As shown at the beginning of the Super Hero Time segment, it was empathizing and highlighted in red that Takaharu does share the same Kanji of 天 with Takeru TenkujiIcon-crosswiki.png (Kamen Rider Ghost). And when looking at their first name in romanji perspective, their names are pretty similar that share five out of six letters from Takeru's name. Furthermore, their civilian outfits are pretty similar to a mix between Western and traditional Japanese style, and the supernatural theme of Kamen Rider Ghost ties better with Ninninger, similar to how Kamen Rider Drive's theme ties better with ToQger.
      • Coincidentally, their actors also share the 西 kanji in their surnames. Also looking at their full names in romanji perspective, they share the first syllables (Shunsuke Nishikawa and Shun Nishime)
  • So far, only AkaNinger and StarNinger have the ability to produce clones without the need of the Kakuranger Legend Nin Shuriken.
  • Takaharu's general quote of "I am fired up" is similar to Natsu Dragneel, the main character of Fairy Tail, followed by Aoi Tategami from KiraKira☆Pretty Cure A La Mode.
  • Having wielded it four times, AkaNinger has used the Gekiatsuto the most following StarNinger who is the sword's primary user.
