Proteoglycan extracted from salmon nasal cartilage, developed at Hirosaki University in Aomori Prefecture. Water-retention capacity approximately 1.3 times that of hyaluronic acid.

Astaxanthin is a carotenoid pigment produced primarily by microalgae (Haematococcus pluvialis), known for strong antioxidant capacity. Japanese production pioneered by Fuji Chemical Industry and ENEOS uses closed-system microalgae cultivation. Multiple Japanese FFC notifications cite astaxanthin for eye health, skin health, and antioxidant support.

Katsuobushi is dried, smoked, and fermented skipjack tuna, one of the foundational ingredients of Japanese dashi stock. The extract form is a concentrated liquid or powder standardized for umami components (inosinate, histidine, amino acids). Export applications include ramen bases, stock concentrates, and umami seasoning bases.

Sea urchin gonads — Japan's most-prized seafood delicacy, one of the three classic delicacies (sankin) alongside karasumi and konowata. Hokkaido (Rishiri, Rebun, Yoichi) and Iwate dominate Pacific-bafun-uni and ezo-bafun-uni production, while Yamaguchi and Kyushu contribute murasaki-uni. Live-shipping in saltwater commands the highest premium; salt-cured and 'shio-uni' preserved formats serve export markets. Distinct from existing seafood entries.

Juvenile sardine and anchovy fry (typically <30mm), boiled and either eaten fresh, semi-dried (kama-age, chirimen), or fully-dried (chirimen-jako). Shizuoka, Kanagawa, Wakayama, Hyogo, and Kochi are the principal commercial harvest regions. Calcium-rich (~2,000 mg/100g dry) and increasingly used as a calcium-fortification ingredient in functional foods. Distinct from existing niboshi entry (which is a smaller-volume, larger-fish anchovy).

Adult Japanese pilchard (Sardinops melanostictus) — the foundation of niboshi (existing), shirasu (juvenile), and the premium adult retail market. Hokkaido, Aomori, Chiba, and Shimane lead commercial harvest; specialty processing in Kanagawa and Wakayama produces salt-cured (shio-iwashi), kabayaki (grilled-eel-style), and dried products. Functional positioning targets DHA / EPA / vitamin-D content. Distinct from existing katsuobushi / niboshi / saba-bushi entries.

Japan's most-fished cephalopod (Todarodes pacificus) — used fresh as sashimi / sushi, dried (surume), as the base of squid-rice (ika-meshi), and as the source of squid ink for pasta / risotto / cosmetic black pigment. Hokkaido (Hakodate), Aomori, and Iwate lead commercial harvest. Substantial export supply for Asian retail and increasingly Western fine-dining. Squid ink (ika-sumi) drives a cosmetic-grade pigment supply chain. Distinct from other seafood entries.

Hydrolysed marine collagen extracted from fugu (Takifugu rubripes) skin — a Yamaguchi Prefecture specialty. Shimonoseki has 80%+ of Japan's commercial fugu industry; fugu-skin upcycled into cosmetic-grade and supplement-grade collagen is a 2010s-onward value-add. Distinct from existing 'hokkaido-marine-collagen' (fish-broad-spectrum) entry. Fugu collagen's high glycine-proline composition gives it favourable bioavailability profiles. Used in beauty drinks, skincare, and joint-health supplements.

Japanese tiger prawn (Marsupenaeus japonicus) — a sushi / tempura premium classic. Aquaculture in Yamaguchi (Akamizu Bay), Kumamoto, and Ehime produces the principal commercial supply; wild-harvest in Tokyo Bay and Seto Inland Sea adds smaller volumes. Distinguished from imported tiger prawns by characteristic stripe pattern and richer umami. Used live-shipped for sashimi (odori-ebi), grilled, tempura, and as a feedstock for chitin / chitosan supplement extraction. Distinct from existing shellfish entries.

Male snow crab (Chionoecetes opilio) — known as 'Echizen-gani' in Fukui, 'Matsuba-gani' in Tottori-Hyogo, and 'Tsuwai-gani' in Hokkaido. Fukui's Echizen-gani has GI protection and tag-trace certification (yellow tag for Echizen-gani, red tag for top-grade). Female (seko-gani) has separate naming and pricing. Northern Hokkaido and Sea of Japan harvest produces the principal commercial supply. Used live-cooked, frozen retail, and increasingly canned for export.

Pacific bluefin tuna — the most-prized sushi / sashimi tuna in Japanese cuisine. Wild-harvest dominated Japanese supply until aquaculture (notably Maruha Nichiro and Kindai University Tuna) began commercial-scale production around 2010. Aomori (Oma), Iyo Bay (Wakayama), and Mie host the principal commercial harvest. The Tsukiji-Toyosu auction system anchors global tuna pricing. Distinct from less-prized yellowfin (kihada) and bigeye (mebachi) tuna varieties.

Japanese amberjack (Seriola quinqueradiata), Japan's most-cultivated finfish by aquaculture volume. Kagoshima, Ehime, and Oita dominate aquaculture; Kanazawa and Toyama Bay provide notable wild harvest of premium 'Kan-buri' (winter buri). Sequential naming as buri grows: wakashi → inada → warasa → buri reflects a uniquely Japanese cultural relationship with the species. Distinct from existing seafood entries.

Japanese sweetfish (Plecoglossus altivelis) — a freshwater amphidromous species harvested from clear river systems. Gifu (Nagara River), Wakayama (Kumano River), Shimane, and Kochi (Shimanto River) host the principal harvest. Iconic 'shio-yaki ayu' (salt-grilled ayu) is a summer fine-dining classic. The fish carries its own characteristic 'sweet' aroma (sugar-fern-like) from its diet of river-bottom algae. Distinct from existing ocean-fish entries.

Japanese red sea bream (Pagrus major) — the ceremonial 'tai' fish central to celebratory Japanese cuisine (weddings, New Year). Aquaculture in Ehime (~50% of national production) and Kumamoto produces the principal commercial supply; wild-harvest in Akashi Strait and Setouchi adds smaller premium volumes. The 'Akashi-dai' wild brand commands the highest pricing. Used in sashimi, grilled, in dashi (tai-meshi), and increasingly in fine-dining-positioned ready-meals. Distinct from existing seafood entries.

Red-meat clam (Scapharca broughtonii) — characteristic deep red colour from haemoglobin (uncommon in molluscs). Sendai Bay (Miyagi), Aomori, and Akita are the principal commercial harvest regions. Used as a sushi / sashimi premium classic; the muscular adductor portion is graded by colour and texture. Distinct from existing seafood entries (scallop, abalone, crab, prawn, octopus / squid). Iron-rich profile drives functional positioning beyond cuisine.

Japanese hard clam (Meretrix lusoria) — a ceremonial-cuisine staple, central to hina-matsuri (Doll Festival) tradition where the matched-pair shells symbolise fidelity. Mie's Kuwana hamaguri carries 'Kuwana-no Yakihamaguri' regional positioning; Aichi and Tokyo Bay (formerly major sources, now declining) round out commercial supply. Production has been declining due to coastal habitat loss; allocation-controlled cooperative supply commands premium pricing. Distinct from existing seafood entries.

Small freshwater / brackish clam (Corbicula japonica) — Lake Shinji (Shimane) and Tone River (Ibaraki / Chiba) are the principal commercial sources. Lake Shinji's Yamato Shijimi commands GI-equivalent regional pricing. Functional positioning targets ornithine content for liver-support / hangover-relief retail (FFC notifications exist, anchored by Yamato Shijimi). Used in shijimi miso soup, freeze-dried supplements, and increasingly as a B2B ornithine ingredient. Distinct from existing seafood entries.

Pacific saury (Cololabis saira) — Japan's autumn-cuisine icon. Hokkaido (Nemuro), Iwate (Ofunato), and Miyagi (Onagawa) are the principal commercial harvest ports. Catches have declined dramatically since 2015 due to changing sea temperatures; supply has shifted toward Taiwan / Russia imports. Used grilled (shio-yaki sanma is autumn-classic), in canned form for export retail, and as a feedstock for fish-oil DHA / EPA extraction. Distinct from existing seafood entries.

Wild-harvest common octopus (Octopus vulgaris) from the Akashi Strait between Hyogo and Awaji Island. The strong tidal currents in the strait produce octopus with markedly firmer, sweeter flesh than other origins. Akashi's takoyaki tradition is anchored in this premium octopus supply. Per-kg pricing is 2-3× imported octopus. Substantial fine-dining and gift-economy positioning. Distinct from existing seafood entries (squid, prawn, crab, scallop).
