Shrimp
As Kanji’s character for “shrimp” is written “海老(Sea, aged ones)”, the long whiskers and curvature of the shrimp’s body are compared to that of an old man, and it has long been considered a symbol of longevity. Therefore, it is used as an ingredient in Osechi dishes with the wish that one will live a long and healthy life in the new year, until one’s waist bends.
