Japan — prawn fishing throughout coastal Japan; Toyama Bay (deep-sea botan ebi), Ise Bay (kuruma ebi), Tokyo Bay (shiba ebi historically), and Suruga Bay (sakura ebi) as regional speciality production areas
Ebi (海老/蝦, prawns and shrimp) occupy a central position across Japanese culinary categories from sushi to tempura to soup. Japan uses multiple species with distinct applications: Kuruma ebi (tiger prawn, Marsupenaeus japonicus) — the premium live prawn for sukiyaki, grilling, and high-end kaiseki; Botan ebi (spotted shrimp, Pandalus nipponensis) — bright red spotted, primarily from Hokkaido, eaten raw as sashimi for their particularly sweet, briny character; Amaebi (sweet shrimp, Pandalus eous) — small, cold-water shrimp with extraordinary sweetness, served sashimi with heads fried separately; Shiba ebi (small Tokyo Bay shrimp) — historically used in Edo-period sushi; Sakura ebi (cherry shrimp, Sergestidae) — tiny, dried, from Suruga Bay near Shizuoka, used as a topping.
Varies dramatically by species: kuruma ebi is rich and savoury with firm bite; amaebi is sweet and cold-water briny, almost confectionery-sweet; botan ebi is complex with a distinctive spotted spotted-shrimp sweetness; sakura ebi is intensely concentrated and oceanic
Kuruma ebi for grilling: grill whole, head on, until just cooked through — the head fat and juices flow back through the body during cooking. For tempura ebi: remove the head, shell while leaving tail, devein, score the belly with 3–4 shallow cuts and gently press flat to prevent curling in the oil. For amaebi sashimi: peel carefully preserving the tail, serve on a small mound of grated daikon or directly on ice. The heads of amaebi can be deep-fried until crispy and eaten whole as a crunchy accompaniment.
Amaebi from Hokkaido (Toyama Bay is also famous for its shrimp) is at its most complex and sweet in autumn and winter — the cold water concentrates the sugars in the flesh. For premium tempura ebi: use live kuruma ebi, cook the prawn tempura to the stage where the juices have barely set inside — the interior should still be barely translucent, not fully white. Sakura ebi scattered over hot rice with sesame oil and soy sauce creates an exceptional simple dish — Shizuoka's sakura ebi don (fresh cherry shrimp rice bowl) during harvest season (April–June, October–November) is one of Japan's great seasonal experiences.
Over-cooking kuruma ebi — the texture goes from yielding and sweet to rubbery in approximately 60 seconds beyond the correct point. Not scoring the tempura ebi belly cuts properly — if insufficient cuts, the prawn curls in the oil and cooks unevenly. Using sakura ebi that has lost its pink colour — faded sakura ebi is old and has lost its characteristic sweet-brine character.
