Kuruma Ebi Japanese Tiger Prawn Live Sashimi Technique
Japanese coastal waters; Mie Prefecture wild; Kagoshima and Okinawa aquaculture
Kuruma ebi (Japanese tiger prawn, Penaeus japonicus) is Japan's most prized native shrimp species—larger than ama ebi, with firm, sweet, complex flavor and a characteristic banded pattern. The prawn reaches peak quality in autumn and winter when shell thickness provides protection of the sweet meat inside. The defining characteristic of kuruma ebi preparation in high-end settings is being served live (ikizukuri sashimi): the prawn is dispatched at the moment of order, the tail shell is removed, and the still-moving flesh is served immediately—considered the ultimate expression of freshness. The firm yet yielding texture of live-served kuruma ebi cannot be replicated with chilled or cooked alternatives. The head is either prepared as kara-age (deep-fried whole until shell crisps) or returned to the aquarium until the guest requests it. Kuruma ebi aquaculture began in Japan in the 1960s (Kinki region) and is now concentrated in Kagoshima and Okinawa. Wild-caught kuruma ebi from Tokyo Bay (Mie Prefecture coast) are increasingly rare and expensive. Preparation: live prawn dispatch by puncturing head, quick shell removal, immediate service with wasabi and soy sauce, or briefly heated in shabu-shabu dashi.
