Mutaito's Electric Rice Cooker

Electric Rice Cookers (電子ジャー, Denshi-Jā) are machines used to cook rice.



Roshi's Electric Rice Cooker

Electric Rice Cookers are the most used container in the Evil Containment Wave technique, with an ofuda talisman stuck on it. After Master Mutaito used the technique, at the cost of his life, King Piccolo spent hundreds of years sealed in one under the ocean after Master Roshi threw it so that nobody could release him.

Roshi and Tien Shinhan attempted to use one each to seal King Piccolo again, but both failed; Roshi's strike missed the cooker and Tien's cooker was destroyed (by training in the manga and by Piccolo in the anime). Aside from the King Piccolo Saga, they do not appear again in the story.

Video game appearances


Roshi's Electric Rice Cooker

An Electric Rice Cooker is trophy No. 41 in Dragon Ball: Advanced Adventure, called "Hot Pot". It appears in Dragon Ball Z: Attack of the Saiyans as a capsule that makes Tien's Evil Containment Wave more powerful. The Rice Cooker also appears as one of the treasures found in the fourth stage of Dragon Ball: Revenge of King Piccolo.


  • King Piccolo shows a great deal of fear when the jar is before him, knowing that he might be sealed within it again.
  • In the FUNimation dub, despite looking like a common rice cooker, Master Roshi describes the jar that Master Mutaito uses as being "specifically designed to hold and contain evil".
