The English description of fugu, the pufferfish served as a celebrated but hazardous delicacy in Japan. Species such as Takifugu rubripes contain tetrodotoxin, a potent neurotoxin concentrated in the liver, ovaries, and skin, with no known antidote. Only licensed chefs who have completed years of training may prepare fugu, carefully removing toxic organs so the remaining flesh is safe to eat. Diners prize its delicate flavour and firm, almost crunchy texture, often served as paper-thin sashimi. Despite strict regulation, occasional poisonings still occur, usually from amateur preparation. The dish’s danger, ritual, and refinement make it one of Japan’s most famous culinary traditions.
