Shimotsuki Ushimaru was a member of the Shimotsuki Family, and the last daimyo of Ringo in Wano Country. He ruled until the takeover of Kurozumi Orochi as shogun 20 years ago.[1] He was a direct descendant of the legendary samurai Shimotsuki Ryuma.[2]

Ushimaru had a pronounced nose and dark blue hair that was somewhat spiky in the front and gathered into a large, bushy bun at the back.[1] Thirty-nine years ago, he wore a dark colored yukata with a light colored marking and a light colored jittoku haori with dark colored images of bulls ( Ushi?). On his back, he has a tattoo of two crossed cutlasses over a circular design, which is a symbol heavily associated with the Shimotsuki Family. After being imprisoned by Kaidou, he wore bandages around his head that covered his left eye. He bore a striking resemblance to Roronoa Zoro, particularly in his youth.[2][3]


Ushimaru was an honorable, selfless, and kind samurai. He opposed the takeover of Kurozumi Orochi[4] and remained steadfast in this even after being imprisoned by Kaidou, his spirit never showing any signs of breaking. When Kaidou attempted to force his imprisoned samurai into a death game over food with his daughter Yamato, Ushimaru and the others showed no hesitation in refusing the food and allowing Yamato to have it, not wavering from the samurai code. Ushimaru displayed exceptional kindness towards Yamato, encouraging the girl's dream to become Oden and bearing no resentment over her heritage as Kaidou's daughter. Ultimately, Ushimaru's selflessness and unwillingness to give into enemy pressure led him to break out of the cave with the other samurai and mount a suicidal final stand against Kaidou purely for the sake of Yamato surviving until the final battle Toki prophesied.[3]

Although he maintained his dedication to the code, Ushimaru considered himself to be a disgraced samurai after being defeated and imprisoned by Kaidou and so humbly declined to share his name with Yamato.[3]

Abilities and Powers

As daimyo of Ringo, Ushimaru had full control over the region.[1]


According to Kawamatsu, he was a masterful swordsman who wielded the blade in a very similar manner to the powerful present-day swordsman Roronoa Zoro.[2] With the aid of Busoshoku Haki, Ushimaru could cut through Yamato's chain and later through a massive boulder using only what seemed to be regular swords provided by Kaidou. When cutting through the boulder, Ushimaru was shown dual-wielding with a sword in each of his hands, and true to Kawamatsu's statement, he was shown with a hunched-over, lunging posture very similar to Zoro's charging attacks.[3]


Ushimaru possessed Busoshoku Haki, which is known as "Ryuo" in Wano. He was shown using it on the swords Kaido gave to his group while imprisoned, drastically increasing the power of his attacks.[3]

Ushimaru served as daimyo for an unknown period of time before 20 years ago, with the komakitsune Onimaru serving as his companion.[1] Twenty years ago, Kurozumi Orochi assumed the title of shogun, and after executing the daimyo of Kuri Kozuki Oden, he gave the remaining four daimyo the chance to submit to him. The daimyo all refused and staged a rebellion against him.[4] The rebellion was ultimately quashed by Kaidou, as Ushimaru and his fellow samurai ended up imprisoned on Onigashima not long after the end of their rebellion. Around that same time, Kaidou locked his daughter Yamato in a cave along with the samurai prisoners for a month or until they agreed to finally obey him. He left them all with food provisions for only a single person, and gave them swords to fight over it. Yamato grew extremely scared, believing the samurai would hate her due to her heritage; however, the samurai proceeded to immediately give her the food, saying they did not feel hunger.

Ushimaru then cut Yamato free from her chains, saying that he had been friends with Oden and that the everyone in the cave adored Oden, and they heard her declaration as him. As the other samurai request to Yamato that he be called "Nobody Important," Yamato shows Ushimaru Oden's journal, but says they have trouble reading it. Everyone proceeds to read it together as Yamato is left amazed by Oden's tales. Ten days later, the samurai tell Yamato that at this rate, they may not be able to see the battle that Oden predicted would happen in twenty years. Yamato says they will fight for Wano that day, but the samurai decide to break out and fight Kaidou immediately to make sure Yamato does not die in the cave like Kaidou wants and that she survives until that day.[3] This ultimately led to Ushimaru and the other samurai's demise.[5][6]


The Ushimaru lookalike daimyo in the manga.

  • Ushimaru's name may come from Ushiwakamaru (牛若丸?), the childhood name of Minamoto no Yoshitsune. Minamoto no Yoshitsune had a retainer named Benkei whose childhood name was Oniwakamaru, which is the possible source of Onimaru's name.
  • In the daimyo meeting with Kurozumi Higurashi posing as Kozuki Sukiyaki 28 years ago, the man sitting to Higurashi's left has the same hairstyle as Ushimaru;[7] however, the anime interpreted him as a different character and gave him brown hair in contrast to the blue hair they gave Ushimaru in Episode 954. In the manga, one of the daimyo in that meeting is completely obscured, though the anime gave him a design which is different from that of Ushimaru.
  • Although he has frequently noted the similarities in appearance between Ushimaru and Zoro, Oda confirmed in the SBS that Ushimaru is not Zoro's father.[8]
