Awabi (鮑 — abalone, Haliotis discus and related species) is Japan's most prestigious shellfish and one of the world's most expensive by weight — live awabi reaching ¥8,000–30,000 per piece at premium Japanese restaurants. Japan's abalone culture is ancient: dried awabi was presented as tribute to the Imperial court since the Nara period, and the Ise Jingu shrine's connection to ama (海女 — female divers) who harvest awabi in Ise-Shima has 2,000+ years of documented history. The premium producing regions: Iwate Prefecture (Sanriku coast) for the largest live awabi in Japan; Chiba Prefecture's Bōsō Peninsula for strong-current wild awabi; Mie Prefecture (Ise-Shima) for the most culturally significant wild harvest through ama diving. Cultivation: farmed awabi (Chiba, Shimane, Miyagi) provides price accessibility while wild maintains luxury status. The preparation split: raw awabi (thin-sliced sashimi) reveals the characteristic oceanic crunch and marine sweetness; steamed awabi (mushi awabi) with sake, found in kaiseki, completely transforms the texture from firm-crunchy to tender-yielding while developing a complex steamed-marine flavour impossible in raw service.

The Japanese system of naming fish differently at each stage of their growth is called shunkan-gyomei (出世魚 — career fish) and the yellowtail-amberjack species provides Japan's most elaborate example. Hamachi/buri (Seriola quinqueradiata) changes name regionally as it grows, and the regional naming differences reveal profound local culinary traditions. In the Kanto (Tokyo) tradition: warasa (small adult, 3–5kg) → buri (full adult, 5kg+). In the Kansai (Osaka/Kyoto) tradition: hamachi (farmed/young adult) → meji → buri. Hamachi is specifically the farmed aquaculture version (from Kagawa Prefecture's Seto Inland Sea primarily) — smaller, milder, less fatty, year-round available; buri is the wild adult, with peak quality in winter (kan-buri — 寒鰤 — 'cold-season buri') December–February when the fish is fattest. Kan-buri from the Sea of Japan coast (Toyama's Himi buri, Ishikawa's buri) is considered Japan's finest winter fish. The fat content of winter buri reaches 21–26% intramuscular fat, creating a buttery, intensely flavoured sashimi that requires minimal preparation. Yellowtail teriyaki and yellowtail kama (collar) are canonical preparations beyond sashimi.

Japan consumes more squid (ika — イカ) per capita than any other nation, with an elaborate species-specific cooking culture that distinguishes between at least eight commercially important varieties with distinct preparation applications. Surume ika (スルメイカ — Japanese flying squid, Todarodes pacificus) is the most abundant — fresh in summer, dried whole (surume) as a long-preserved snack, or used in ika-sōmen (squid noodles made from thinly sliced body). Aori ika (アオリイカ — bigfin reef squid) is the premium sashimi squid: thick, sweet, translucent white flesh that holds its texture well; expensive and seasonal. Yari ika (ヤリイカ — spear squid, Dec–April): delicately sweet, thin-walled, excellent for sashimi and ika-meshi (stuffed squid with rice). Mōka ika (モウカイカ) and hotaru ika (ホタルイカ — firefly squid) are seasonal specialties: firefly squid from Toyama Bay (March–May) bioluminescent when alive, served either raw with miso-vinegar sauce or blanched briefly. Processing techniques: ika-sōmen (sliced raw into noodles, 2mm width, served cold with ginger-soy dip); ika-yaki (whole grilled); ika-karaage (deep-fried); ika-teriyaki; ika no shiokara (塩辛 — heavily salted fermented squid gut, Japan's most acquired taste condiment).

Suzuki (鱸 — Japanese sea bass, Lateolabrax japonicus) is Japan's most important coastal white-fleshed saltwater fish for sashimi and grilling, with a complex seasonal reputation: summer suzuki (mai-suzuki — 'dancing sea bass') is considered peak quality as the fish is fattest and most active; autumn suzuki returns from summer feeding in brackish river mouths to sea and begins declining. The suzuki lifecycle creates an annual quality narrative: spring juveniles (seigo — up to 25cm) are distinct from adult suzuki (25–60cm) and the largest adults (ookina suzuki — 60cm+), with Japanese cooking treating each size stage as functionally different ingredients. Suzuki's flesh is notably firm and white with a clean, mild flavour that expresses heat application exceptionally well — especially en papillote (salt-crust whole roasting) and sashimi. The by-product culture around suzuki: suzuki kama (collar) is broiled; suzuki heads are made into ara-ni (骨煮 — simmered fish bones and head in soy-sake). Tsukudani (佃煮 — Tokyo-style sweet soy-simmered foods) originally developed in Tsukuda Island in the Edo period using small fish and shellfish — any suzuki trim, small seigo, or shellfish are simmered into this concentrated preserving preparation.
