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.
