What is Hohoniku?
Hohoniku (頬肉) is the cheek meat of the Bluefin Tuna — the dense muscle clusters on either side of the jaw. There are only two per fish, which makes the total yield extremely limited. Most of this meat never leaves Japan.
The texture is unlike any other cut: densely fibered, with a depth of flavor that customers consistently compare to premium beef before they reach for fish comparisons. The cheek muscles of any animal that feeds constantly in open water develop an intensity the more sedentary cuts do not.
Availability: Two medallions per fish means supply is inherently limited. Available at market price when the weekly Bluefin allows — check the shop or ask in-store.
How to eat it
As a steak — the preparation that shows it best. Sear over high heat, briefly, and do not overcook. The exterior caramelizes in seconds while the interior stays rare. The texture at that point is extraordinary: the tenderest cut of beef you have ever had is the closest comparison, but Hohoniku has a depth of umami that beef does not. Cut against the grain, rest briefly, serve immediately.
Also excellent as straight sashimi — slice slightly thicker than belly cuts, against the grain. The meaty, dense character is present even raw, but the brief sear amplifies it.
Where this fish comes from
Every piece of Bluefin Tuna at Sashimi DC comes from Hosei Suisan (宝生水産), a farm in the Kamishima Wakamatsu area of the Goto Islands, Nagasaki Prefecture — the westernmost islands of Kyushu, where the Pacific and East China Sea converge.
The Goto Islands maintain water temperatures that never fall below 13°C in winter and rarely exceed 29°C in summer — the stable, narrow range that Bluefin Tuna require for consistent growth and quality. Hosei Suisan operates in the Kamishima Wakamatsu area, one of the most environmentally favored zones for marine aquaculture within the islands.
Hosei Suisan uses wild-caught seed stock (天然種苗) rather than hatchery-bred fish. Feed is sourced fresh and locally, centered on fresh mackerel (生サバ) bought directly by their own trucks from local fishermen. Director Tsuneya Yamashita explains the choice: mackerel produces better fat marbling and color than sardines. As mackerel catches have declined and prices risen in recent years, they secured dedicated year-round supply agreements with their fishing partners to maintain the standard. Post-harvest handling — the initial processing and preparation after the fish is landed — is also a focus: Ikejime is performed in Nagasaki, at source.
Two-time award winner: At the Nagasaki Prefecture Farmed Bluefin Tuna competition on December 8, 2023 — showcasing the fish from Japan’s leading farmed Bluefin production prefecture — Hosei Suisan was awarded the top prize (最優秀) for the second time.
After Ikejime processing in Nagasaki, the fish is transported to a specialist Miyazaki processor where it is broken down into saku blocks, then flown Fukuoka → Haneda → IAD.
