Yosaku along with Johnny are old friends and former bounty hunting partners of Roronoa Zoro.


Yosaku has a black shirt with a green coat and red headgear. He has plaid yellow shorts over unshaven legs and dark shoes and, like his partner, carries a sword. He is also sometimes seen with a cigarette.

After the timeskip, Yosaku is no longer wearing the coat and is seen shirtless, showing he has a kanji tattoo that reads "Big Catch" (大漁 Tairyō?) on his back. His arms have become very muscular.


When he is with Johnny, the pair often stand together side by side, with one arm across the chest and the other at their mouths. While like this, their voices and behavior become serious, however in truth, they are very silly and emotional. Yosaku is the more emotional of the pair and he can spend hours crying over stories of difficult times and struggles. He tends to get frustrated and even upset when no one pays attention to him when talking. Like Johnny, he has a fair amount of knowledge regarding rumors and the world but lacks the finer details. He was partly blamed by Zoro for their misinformation over "Hawk-Eyes" and "Drunk-Eyes".

He prefers to avoid danger like Johnny, but unlike Johnny, he quickly forgets his fears if distracted by something else like food[2] or by being moved by a story linked to the fear. When he is spurred on is brave enough to go against Arlong and his crew and wise enough to know that if they did not stand a chance against Arlong and his crew the villagers they made suffer would be slaughtered. One quirk he shares with Johnny, perhaps out of pride, is always stating that any fight he loses, he lost only by a hair.


Both swordsmen respect and admire power, as proven by their constant praising of Zoro's power, and later the Straw Hat Pirates power. Anyone who has earned their respect will be acknowledged by them as "Aniki" (brother) or "Aneki" (sister).

Abilities and PowersEdit

Yosaku is a swordsman like Johnny, however they are relatively low in strength and power. As for example when they tried to take on the Arlong Pirates by themselves they were easily overpowered.

He and Johnny are inexperienced with traveling by sea as proven when Yosaku fell ill to scurvy. However, he and Johnny are fairly knowledgeable about the world at large, such as information on the existence of the Shichibukai and the Arlong Pirates; he even identified Mohmoo as a Grand Line monster upon first glance when the Sea Cow confronted the boat that he, Luffy and Sanji were on, hinting some degree of experience.[3] They are, however, still incompetent and have been known to slip up, as when they reported Hawk-Eyes had been reported at the Baratie when it was actually "Drunk-Eyes".


Yosaku uses a sword, that resembles a dadao, with a red handle and a circular tsuba. The blade of the sword gets broader as it gets farther away from the hilt. He does not appear to own a sheath for it, as it is shown being hung on his waist with a piece of looped cloth rather than a sheath.


East Blue SagaEdit

Baratie ArcEdit

They arrive on the scene after Usopp and Luffy unknowingly shoot at the tiny island they are on for target practice. The partners had to stop because Yosaku was suffering from scurvy, but Nami was able to diagnose and treat him. This incident proved to be helpful for the Straw Hats, as it made them realize the importance of finding a cook for their crew to avoid any food-related seaborne illnesses since Yosaku only got sick from eating rotten fruit. The two help the Straw Hats with that problem by directing them to the Baratie.[1]

During the Baratie arc, Johnny and Yosaku remain on the Going Merry to rest and notice Nami's interest in their wanted posters.[4] As Dracule Mihawk arrives at the Baratie, Nami tricked Yosaku and Johnny and escaped with their treasure and boat.[5] She had them to drop their guard by pretending she was changing her clothes and asking them to turn around. With their backs turned, she pushes them off the Going Merry and stole the ship.[6] After explaining what happened to Luffy, the two witness Zoro being defeated easily by Mihawk,[7] before Johnny and Yosaku leave with Usopp and the wounded Zoro to pursue Nami.[8]

Through means that are still unknown, Yosaku later returned to the Baratie in the mouth of a wild panda shark shortly after the Krieg Pirates left to pick up Luffy, explaining that Nami was headed to a dangerous place and they needed his help. After Sanji agrees to join Luffy's crew, the three departed to Arlong Park.[9]

Arlong Park ArcEdit

While on the way, Yosaku explains the story about how when Jinbe agreed to become a Shichibukai, a government recognized pirate, his former comrade Arlong had founded his own crew and had been sent into the East Blue as part of the agreement. Yosaku even clearly stated that Jinbe set Arlong free to East Blue in exchange for his seat as Shichibukai. This resulted in Arlong terrorizing the East Blue, and built his own place Arlong Park which is their current destination, since both he and Johnny were able to figure out that Nami was heading there due to both the direction of the ship and that Nami's earlier behavior was related to Arlong, because of her obsession with Arlong's wanted poster.[10]

Yosaku and Johnny Block Arlong Park

Yosaku and Johnny block Arlong Park entrance.

Once Luffy and Sanji defeat the Arlong Pirates' pet Mohmoo, they are able to use it to tow themselves to Arlong Park to get there faster.[11] However, after recognizing that the Straw Hats will try to win Nami back by defeating Arlong, the two decide to back off and retreat out of fear for their own lives.[12] But once they hear Nojiko's story about Nami's tragic past and why she had to join Arlong, the two attempt to face Arlong's crew for having misjudged Nami only to be easily defeated. Recognizing that only the Straw Hats can defeat Arlong and his crew, Johnny and Yosaku stop the villagers from throwing their lives away.[13] During the battle, Yosaku, along with Johnny lend Zoro their swords to replace the ones that Mihawk broke at the Baratie so he could defeat Hatchan. After Arlong's defeat, they thank the Straw Hat crew for their assistance but continue their life as bounty hunters.[14]

Fishman Island SagaEdit

From the Decks of the WorldEdit

Johnny and Yosaku are seen fishing from a boat near Cocoyasi Village.[15]

Translation and Dub IssuesEdit

  • Yosaku's cigarette was edited out in the 4Kids dub.
  • The original pronunciation of Yosaku's name was with emphasis on the second syllable. While this was kept in the 4Kids dub, the FUNimation dub pronounces it with emphasis on the first syllable.
