Not to be confused with Kotaro Nogami, Ryotaro's grandson, who became New Den-O

"Kotaro" is the eleven-year old version of Ryotaro Nogami that he met during the events of Kamen Rider Den-O: I'm Born!, nicknamed Kotaro to differentiate him from his present, older self.

I'm Born

Ryotaros

Both Ryotaros.

When Ryotaro and Hana are trapped in the year 2000 by Kamen Rider Gaoh they encounter Ryotaro's child self. With Ryotaro lacking memories of being Kamen Rider Den-O due to being attacked by Gaoh and unable to transform, the young Ryotaro is given the nickname Kotaro and decides to go with them to stop Gaoh's plans. During a fight with ninjas in the Edo Period, Momotaros possesses him with his contract to Ryotaro extending to the past and transforms into Kamen Rider Mini Den-O.

After the battle Kotaro is brought back to his time but not before seeing his late parents and then bids the gang farewell.

Onigashima

As a result of an unknown force altering the present Ryotaro is regressed into an adolescent form. While investigating an error in time with Deneb and Kamen Rider New Den-O he encounters a child Yuto Sakurai. Later after finding three of the scattered Tarōs and going into the time of the battle against Oni Island Ryotaro reunites with Momotaros and fights alongside everyone.

Despite being a child, Ryotaro does not assume Mini Den-O, instead becoming an adult Den-O. This is possibly because unlike Kohana who was regressed into a child due to her future being recreated, Ryotaro was de-aged as a result of an unknown tampering of time.
