Kasugo refers to the young sea bream. Among seasonal fish, its cherry blossom-like skin color and the aura from its small body stand out remarkably. Kasugo generally refers to the juveniles of various sea bream species, particularly red sea bream (madai), yellow sea bream (kidai), and crimson sea bream (chidai). The yellow sea bream is also known as renkodai. Interestingly, while fully grown sea bream is classified as white-flesh fish (shiromi), the juvenile kasugo is categorized as hikarimono (silver-skinned fish). Juveniles are usually defined as fish weighing under 100g (less than 14 cm in length).
