Kotaro Nogami (野上 幸太郎, Nogami Kōtarō) is a fictional protagonist and character in the series of films for the 2007 Kamen Rider Series Kamen Rider Den-O. Kamen Rider New Den-O first appears in the 2008 film Saraba Kamen Rider Den-O: Final Countdown and reappears in the Cho Den-O Series. Later, he appeared again with Kamen Rider OOO in OOO, Den-O, All Riders: Let's Go Kamen Riders.


He is introduced as the grandson of Ryotaro Nogami (and is consequently Hana's second cousin and Airi's second nephew) and is the newest Singularity Point who can become a Kamen Rider. Originally impressed by Owner's stories of his grandfather's time as Den-O, Kotaro eventually entered a contract with the Imagin Neotaros (ネオタロス, Neotarosu?). Because the time stream had been endangered, he was called by the past's Owner to fight the new threat, picking up the slack from his grandfather whom he has a grudge against for both naming him and inheriting his bad luck. To further distance himself from Ryotaro, Kotaro renamed his Imagin partner Teddy. However, Kotaro regains respect for his grandfather as they restore the time stream.
