One Piece Wiki

The All Blue is a rumored sea of legend, said to be the only place in the world where the North Blue, South Blue, East Blue, and West Blue seas meet. It was first mentioned in Chapter 56 and Episode 26, where Sanji and some chefs discussed if All Blue even exists.

Finding the All Blue is the dream that Sanji strives to achieve. It was also the dream of his mentor Zeff.


Though the All Blue has yet to appear in the series, it is said that in this legendary ocean, there are fish from each of the four seas, and to have such a resource at one's disposal is the ultimate dream of every chef. It is believed that the All Blue is somewhere in the Grand Line.

There have been several hints in the series that make it appear that the All Blue truly does exist, though only in anime filler episodes. During Sanji's cooking battle in a Loguetown Arc filler episode, it was mentioned that some fish species that should not exist in the East Blue were found due to ocean currents, which made Sanji certain that the All Blue exists. In a Water 7 filler episode, Sanji finds another hint of the All Blue's existence. Salt is brought by the Aqua Laguna from all the seas and Sanji compares it to the All Blue. It is shown to be such a good seasoning that a small amount in food is enough to outclass even his own cooking.[1]
