One Piece Wiki

The sakazuki (or "sake cups"), refers to a formal ceremonial process in which two or more individuals form a bond akin to that of family in an exchange of sake cups.


Pirates appear to perform sakazukis when establishing a fleet.[2][3][4] It is also to be used by the yakuza of Wano Country.[5]

Three types of sakazuki have been featured so far:

  • Brothers' Sake Cups (兄弟盃 Kyōdai Sakazuki?) - used during a formation of a brother-brother relationship.
  • Parent-Child Sake Cups (親子の盃 Oyako no Sakazuki?) - used during a formation of a parent-child relationship.
    • Followers' Sake Cups (子分盃 Kobun Sakazuki?) - used during a one-sided pledge of loyalty.

Brothers' Sake Cups are performed between equals, signifying a relationship like that of brothers. Parent-Child Sake Cups are usually performed between a superior and their subordinate, to signify a parent and child relationship.

After all individuals involved have sake poured in their respective cups (with the largest cup in the possession of the leader in the event of Parent-Child Sake Cups) they make an oath or perform a toast before drinking from the cup, swearing themselves to each other.[3] It also seems that the individuals get to keep their respective cups, and when one party returns it, it signifies cutting ties with the other person.[4]

In One Piece episode A, a formal Oyako-Sakazuki is performed, where several other positions are revealed. The sakazuki included an overseer, who acted as a master of ceremonies, a cupbearer, an observer and a witness, though the purpose of the following three positions in the ceremony is not expanded.
