If all vegetables were like Potato-dono, I would become an omnivore. The flavor of the kill is always enhanced when the prey fights back and I’m sure Potato-dono would have put up one hell of a fight.
Just FYI, around 23 sec into the video, you see potato-dono preparing to peel himself. He is kneeling on a white mat/tatami and the peeler is on a small stand in front of him. This is a pretty accurate depiction of the ritual associated with seppuku. As described in this fairly detailed description of seppuku, the ritual often took place in a large room on which a white tatami had been placed or outside in a garden. The high ranking samurai committing seppuku would kneel in seiza and low wooden table would be placed in front of him/her. The bare blade that was going to be used for seppuku would be placed on the table on top of a stack of folded white paper (everything in this ritual is white – the outfit, the mat, the paper. White symbolizes purity for the Japanese too). The white paper is used by the samurai to hold the blade while cutting into the belly. This was necessary because the seppuku blade usually did not have a handle since the blade would be discarded after the suicide (waste of a good weapon, if you ask me). Potato-dono didn’t need paper since the peeler had a handle, I guess. Potato-dono being assisted by the carrot to complete the ritual is also somewhat true to the seppuku tradition. The samurai would often have a second who’s job it was to finish the job by cutting off the samurai’s head once they disembowled themselves (something only the most disciplined samurai could accomplish).
So you got a little lesson in culture along with your cartoon entertainment. Isn’t that special?
