Kawamatsu the Kappa is a samurai of Wano Country who once served Kozuki Oden until Oden's death 20 years ago.[1] He is currently a prisoner of the Beasts Pirates in Udon's Prisoner Mine.[4] He is also one of the Nine Red Scabbards.[2]


Younger Kawamatsu

Kawamatsu as he appeared over 20 years ago.

Little is known about Kawamatsu's appearance but according to Hiyori, he is a Kappa and also proud of that fact. So far, he was only shown in flashbacks wearing a light colored kimono and a large kasa with a dark diamond shape at its top,[3] and in the present day, shrouded in shadows in a dark cell.[1]


Kawamatsu's Kappa Dance

Kawamatsu dancing to try and cheer Hiyori up after she was traumatized by her parents' deaths.

He is very kind and caring as when one of the Beast Pirates attempted to attack Luffy, Kawamatsu silently aided him by attacking with a fish bone. After Hiyori was deeply traumatized after her parents' death, Kawamatsu did everything he could to cheer her up and even made jokes about his hunger. He seems to like fighting, as when Luffy and Hyogoro were battling in their execution, he expressed his desire to sumo fight as well.

Like other characters, Kawamatsu possesses a unique laugh: "Kappappappa".[5]


Kozuki FamilyEdit

As Oden's retainer, Kawamatsu is extremely loyal to the Kozuki Family. He was the one who helped Hiyori escape from their enemies at Oden Castle and took care of her for 7 years during her childhood until he was captured and imprisoned. After reuniting with Raizo after twenty years, the first thing he did was asking about Momonosuke's safety, showing his concern for Oden's son. Unlike Ashura Doji, Kawamatsu is eager to join the Kozuki Family in the war against Orochi and Kaido.


Beasts PiratesEdit

During his 13 years of imprisonment at the prisoner mines, Kawamatsu refuses to submit to his enemies and defiantly stays in his cell chained up.

Abilities and PowersEdit

Along with Denjiro and Ashura Doji, Kawamatsu is considered by Kin'emon to have been one of Oden's most powerful followers, being worth 100 men in battle.[1] He is a fast digger and swimmer, which enabled him to sneak Hiyori out of Oden Castle.[3]

Kawamatsu has immense endurance as he has been fed poisoned fish every day for thirteen years by the Beasts Pirates without dying or even suffering any illness like Tama, a feat which has baffled his captors.[6] He was also shown to go on while starving himself while providing for Hiyori.[3]


He is capable of spitting projectiles with great speed and precision, potentially turning them into deadly weapons if they are sharp enough. Thus, his guards are ordered to remove the bones of the fish they feed him. When they failed to do this, he was able to take out a guard by spitting the bone as a projectile that pierced his neck.[6] He was also shown carrying a sword.[3]



Kawamatsu Takes Care of Hiyori

Kawamatsu takes care of Hiyori.

Sometime after the Nine Red Scabbards were assembled, Yasuie caught them stealing money from him. Instead of punishing them, Yasuie allowed them to take the money and encouraged them to use it to become better people for the sake of Kozuki Oden and Wano.[7]

Kawamatsu served under Oden until the latter was executed 20 years ago.[1] After Momonosuke and some of Oden's retainers were sent to the future by Toki, Kawamatsu helped Hiyori escape the destruction of Oden Castle and took care of her[3] until they were separated seven years later.[5] He was imprisoned in Udon where he was fed with a poisonous bone-less fish each day.[6][4]

Wano Country ArcEdit

After Monkey D. Luffy was brought to Udon, Kawamatsu spat a fishbone at one of the guards when the guard attempted to attack Luffy.[6] He later witnessed Dobon's confrontation with Luffy and Eustass Kid.[8]

When Luffy and Hyogoro were brought before Queen, Kawamatsu called out to Raizo while the ninja was in front of his cell. After revealing himself, he asked if Kozuki Momonosuke was okay.[4] He then asked Raizo to help him escape so he could join the decisive battle against the Beasts Pirates during the Fire Festival. Raizo was spotted and forced to disappear in a smokescreen. Kawamatsu then noticed how Luffy had been causing a commotion and prayed that he would not let Hyogoro die.[5]

Kawawatsu cries

Kawamatsu tearfully watched Yasuie's execution.

Sometime during the Sumo Inferno, Kawamatsu commented that he wanted to try a sumo match as well.[9] On the next day, Kawamatsu watched the broadcast of Shimotsuki Yasuie's execution with tears in his eyes.[10]


  • The name Kawamatsu (河松?) literally translates to "river pine", while the term kappa (河童?) means "river-child".
