This article is about a/an ally in Kamen Rider OOO.

Tokugawa Yoshimune (徳川 吉宗) is the eighth shogun of the Tokugawa Shogunate of Japan. He appears as a major character in Kamen Rider OOO Wonderful: The Shogun and the 21 Core Medals providing Eiji Hino the orange Core Medals.


While Yoshimune is a responsible shogun and leader, he desires freedom and roams around Japan disguised as a samurai named Tokuda Shinnosuke (徳田 新之助). As shogun he takes his responsibilities very seriously, fighting enemies that threaten his country that others would run from. Seeing Kamen Rider OOO as an ally, he gives him the orange Core Medals that was given to him as a gift from Europe.


As the shogun, Yoshimune is trained in swordsmanship and battlefield strategy, effectively fight against several enemies including Gara's Knights which is difficult for the average human. He is also a skilled horseman, riding his personal steed wherever he goes even in major battles.


Prior to meeting OOO, Yoshimune received a gift from Europe, a set of three mysterious coins that people knew little about. By the time the Knights and the Nue Yummy invaded looking for the coins he encountered Eiji Hino and company. He then fought alongside Eiji as Kamen Rider OOO and in the battle with the Nue Yummy, he tossed the Core Medals to OOO allowing him to become Burakawani Combo and destroy the Nue Yummy.


  • This character is based on the real-life Tokugawa Yoshimune, the eighth shogun of the Tokugawa shogunate of Japan, who was ruling from 1716 until his abdication in 1745. Actor Ken Matsudaira had played him for the past 25 years on the long-running but recently ended series Abarenbo Shogun, which The Shogun and the 21 Core Medals is a crossover with.
  • In Kamen Rider: Battride War II, he would be featured in the game as a special playable character who will ride a horse, instead of a bike. This is due to that he is from the past.
