The Straw Hat Pirates are the main focus of the One Piece anime and manga series, and Sanji is the fourth member to join the crew. Known as a talented chef, Sanji dreams of finding All Blue, the legendary ocean that unites fish from all over the world. However, there are many interesting facts about Sanji that most fans don’t know. Here are 20 unique facts about Sanji that you may have never heard of!

20 Hidden Facts about One Piece Sanji

1. The Only Straw Hat Pirate with Siblings

Sanji comes from the Vinsmoke Family, rulers of the infamous Germa Kingdom. He has four siblings: Ichiji, Niji, Yonji, and Reiju. His three brothers frequently bullied him for being the weakest in the family, while Reiju secretly tended to his wounds.

2. Sanji’s Original Design Was Very Different

Before his current look, Eiichiro Oda originally designed Sanji with a classic pirate outfit, black hair, normal eyebrows, and firearms. However, Oda later changed his design to feature a sleek suit and a kick-based fighting style.

3. Has His Own Spin-Off Series

Sanji stars in a spin-off series titled Shokugeki no Sanji, created by the Shokugeki no Soma team. This series focuses on his time at Baratie and consists of six chapters available on the official Shonen Jump app.

4. Sanji Was Originally Designed as a Gunslinger

In the early concept, Sanji was supposed to be a sharpshooter. However, Oda flipped this idea, making him a chef who only uses his hands for cooking while relying on his legs in combat.

5. Favorite Cigarette Brand

Sanji is a heavy smoker. Oda revealed that he smokes two fictional brands: King Ground and Death, though the latter doesn’t exist in real life.

6. His Dream Devil Fruit

As a child, Sanji read about the Suke Suke no Mi, a Devil Fruit that grants invisibility. He was disappointed to learn that Absalom had already eaten it. However, in the Wano arc, he gained a similar ability through his Raid Suit, though he later destroyed it.

7. Unique Facts from SBS

In the SBS (Shitsumon o Boshū Suru!) Q&A section, Oda revealed several fun facts about Sanji, including that he bathes regularly and his favorite color is blue.

8. Would Be Impeached as a President

In an interview, Oda joked that if Sanji were a president, he would pass laws granting special privileges to women. However, he would soon be overthrown as men would revolt against him.

9. A One Piece Plot Hole

In the Baratie arc, Sanji claimed he didn’t know Devil Fruit users couldn’t swim. However, in the Thriller Bark arc, he stated he had known this since childhood. This is considered a minor plot hole in the series.

10. Connection to the Number Three

Sanji has multiple ties to the number three:

• His name contains “San” (3 in Japanese).
• His birthday is March 2nd (3/2 = "San" & "Ji").
• He is the third son in his family.

11. Inspired by a Celebrity

Many believe Sanji’s design was inspired by Leonardo DiCaprio, but Oda actually based him on Steve Buscemi’s character, Mr. Pink, in Reservoir Dogs. While they don’t share physical similarities, their attire and facial expressions are strikingly similar.

12. Unique Nicknames for Nami and Robin

In Japanese, honorifics like "-san" and "-chan" hold specific meanings. Typically, "-san" is used for elders, and "-chan" for younger individuals. However, Sanji reverses this, calling Nami “Nami-san” and Robin “Robin-chan.” Oda explained that Sanji does this to make older women feel younger and younger women feel mature.

13. Sanji Was Almost Named Naruto

Oda initially planned to name Sanji “Naruto.” However, after learning that Masashi Kishimoto was launching a manga titled Naruto, Oda changed the name to avoid confusion.

14. A Different Real-World Career

If Sanji lived in the real world, he wouldn’t be a chef but a hairdresser. Oda mentioned that Sanji frequently helps trim the Straw Hats’ hair. Additionally, if Sanji were real, he would be from France, known for its culinary culture.

15. The Ideal Devil Fruit for Sanji

Despite his strength, Sanji does not possess a Devil Fruit. However, if he had one, Oda suggested it would be the Swim-Swim Fruit, owned by Senor Pink. This fruit allows users to "swim" through solid objects, fitting Sanji’s habit of peeping on women.

16. Sanji Has Never Been Sick

In one episode, Sanji mentioned he has never been sick. Though just a brief statement, it’s interesting considering he lives in a world filled with extreme weather and dangers.

17. Favorite and Least Favorite Foods

As a chef, Sanji values food. He loves seafood and spicy pasta paired with black tea. However, he dislikes konjac, which he considers nutritionally useless, and ice cream, which he finds unappealing.

18. Censorship in the 4Kids Dub

In the 4Kids English dub, Sanji’s smoking habit was censored. His cigarette was replaced with a lollipop to make the show more child-friendly, part of the broader censorship policies in the U.S.

19. Sanji Dislikes His Brothers

Sanji has a poor relationship with his Germa 66 siblings, except for Reiju, who treated him kindly. However, unlike with other women, he does not show any romantic reactions toward her.

20. Sanji Can’t Fight Women

Sanji follows a strict code never to harm women, even in battle. This was first shown during his fight with Kalifa of CP9, where he refused to attack her despite being in danger. This principle stems from his respect and love for women, a lesson taught by his adoptive father, Zeff.

Sanji is a complex character with many hidden details that fans often overlook. From his unexpected design inspirations to his unique habits, he remains one of the most beloved characters in One Piece. With his incredible cooking skills, distinctive fighting style, and strong principles, Sanji continues to be a crucial member of the Straw Hat Pirates.
