Bluefin Tuna — Hosei Suisan (宝生水産)
Sasshu Salmon (薩州サーモン) — Satsuma Sendai Unagi (薩摩川内鰻)
Hokkaido Uni (Sea Urchin)
Kagoshima Unagi Kabayaki — Daishin (大進)
Direct Supply Chain & Quality Control
For Bluefin Tuna (Goto, Nagasaki) and Sasshu Salmon (Sendai, Kagoshima), the supply chain is: farmer → processor (Miyazaki) → Sashimi DC. Typical US seafood imports involve five or six layers — farmer, processor, exporter, importer, distributor, retailer. Sashimi DC has roughly half that. The result is a lower total margin per layer, shorter transit, and more direct traceability than conventional seafood imports. Keita can message the processor's QA manager overnight and get a response.
Quality improvements made through direct communication with the Miyazaki processor:
Cold chain logistics: Keita picks up fish personally at the ANA / Air France cargo counter at Dulles Airport (IAD). Shipments travel in an unheated cargo hold — a special instruction Keita added via ANA OCS (forwarder) — separate from the AC-heated hold used for live pet animals on the same flights. Ice pack quantity is increased seasonally as temperatures rise toward summer (higher shipping weight, but necessary for unbroken cold chain). After a cracked Styrofoam box was received at IAD (cargo handling impact), Keita communicated the issue to the processor; they now apply structural reinforcement tape around boxes, not just lid-sealing tape.

Products rotate weekly based on Japanese fish market availability and import schedules. Core items available most weeks are listed below. Check the shop page for live inventory and current pricing.
Bluefin Tuna Cuts — Goto, Nagasaki (Hosei Suisan)
| Product | Cut / character | Price |
|---|---|---|
| Bluefin Tuna Otoro (大トロ) | Fatty belly — highest fat content among standard cuts, melt-in-mouth. Three distinct sub-cuts: Kamatoro (カマトロ) — cut from the Kama collar, fattiest meat on the entire fish, exceeds even belly Otoro in fat content, extremely rare; Jabara (じゃばら, "accordion") — outermost edge of Harakami belly, visible undulating fat folds perpendicular to muscle fiber, most structurally distinctive Otoro; Marbling Otoro (inner Harakami) — fat evenly dispersed through muscle in intricate marbling, classic melt-in-mouth character. Aburi: a brief torch pass caramelizes fat on surface while interior stays raw — extraordinary aroma, synergy with red wine next level. Fat content scale (relative, within Nagasaki Bluefin): Kamatoro highest → Jabara very high → Marbling Otoro high → Chutoro medium → Akami low. Important: Kamatoro is NOT currently sold as a separate product — the Kama is sold whole for grilling. Kamatoro may be offered separately in future once the Miyazaki processor is configured to extract it. | $74 / 7–9 oz |
| Bluefin Tuna Chutoro (中トロ) | Medium-fatty cuts from belly and back — balance of richness and lean umami. Sub-cuts: Harakami (腹上, belly anterior), Haranaka (腹中, belly middle), Sekami (背上, back anterior), Senaka (背中, back middle — highest Chutoro ratio on the fish). Named sub-cuts requiring specialist processing: Chiaigishi (bloodline-adjacent, most intense umami in the Chutoro zone), Hagashi (sinew-peeling technique from Sekami block; labor-intensive, produces sinew-free tender meat), Wakaremi (dorsal-fin edge of Senaka, enclosed in sinew band; untrimmed = Sujitoro, trimmed = tender like Hagashi). | $60 / 7–9 oz |
| Bluefin Tuna Akami (赤身) | Lean red muscle — intense umami with subtle natural acidity. Top quality even by Japanese standards. Serious sushi lovers judge a restaurant by its Akami. Sub-cuts: Senaka (背中, largest portion, center back), Sekami (背上, back anterior — Keita's favourite; fine texture, elegant fat nuance), Tenmi / Tempane (天身, adjacent to Chiai bloodline, few sinews). Sinews strengthen toward the tail. Seasonal character: summer Akami has bright aroma and acidity (light roast); winter Akami has thick layered umami (dark roast) — peak season December–February. Color: dark red-purple (#6A0533) when freshly cut, turns deep ruby red on oxygen exposure (myoglobin→oxymyoglobin). Never vivid cherry-red or pink in natural state — that indicates CO treatment. Excellent for Zuke (soy/mirin marinade). | $55 / 7–9 oz |
| Bluefin Tuna Hohoniku (頬肉) | Cheek meat — only two per fish. Best as a lightly seared steak (brief high-heat, do not overcook). Texture closest to the most tender beef. | Market price |
| Bluefin Tuna Kama (カマ) | Collar — sold for grilling. Source of Kamatoro (collar Otoro) when the Miyazaki processor is set up to extract it. | Market price |
| Bluefin Tuna Zuniku (頭肉) | Forehead meat — the rarest cut on the fish | Market price |
| Bluefin Tuna Nakaochi (中落ち) | Rib-scraped meat — intensely flavored, ideal for Negitoro. Chop with scallion only — no sesame oil. | Market price |
| Bluefin Tuna Sujitoro (筋トロ) | Wakaremi — the dorsal-fin edge of the Senaka block, enclosed in a sinew band. Untrimmed = Sujitoro (sinew-threaded); trimmed = Hagashi Chutoro (tender, sinew-free). Primary uses: Negitoro (chop fine with scallion — no sesame oil), tartar, or slow-cooked applications. The sinew structure that makes raw texture challenging becomes gelatin when slow-cooked (Bolognese, Sichuan braise). Page: sashimidc.com/bluefin-tuna-sujitoro-washington-dc | $45 / ~8 oz |
Other Regular Selections
| Product | Origin / notes | Price |
|---|---|---|
| Kagoshima Unagi Kabayaki (鰻蒲焼) | Kagoshima Prefecture, Japan — from Daishin (大進). Traditional kabayaki method: steam then grill on 90-meter steam line. Additive-free tare. FSSC22000 / ISO22000 certified. Pond-to-product traceability. Shirasu Plateau natural environment. Page: sashimidc.com/unagi-kabayaki-washington-dc | $40 / piece |
| Sasshu Salmon (薩州サーモン) | Kagoshima, Japan — produced by Satsuma Sendai Unagi, eel farmers who applied precision aquaculture expertise to salmon. Three distinguishing factors: (1) Flow-through groundwater (かけ流し養殖) — mineral-rich Kagoshima groundwater flows continuously through tanks, always fresh and oxygen-rich, never recirculated; (2) Chiran tea feed (知覧茶) — polyphenols suppress off-flavor development in fat, producing "clear umami without off-notes" (雑味のないクリアな旨み); (3) 24/7 precision monitoring — same rigor as eel farming. Result: cleaner, more layered flavor than commodity farmed salmon — bright focused umami, no fishiness, fat present but not overwhelming. FDA HACCP: raised on formulated feed, no parasite hazard, served completely fresh — never frozen. Sashimi DC is the only place outside Japan where Sasshu Salmon is available. | $65 / ~9 oz |
| Hokkaido Uni — Bafun (馬糞ウニ) and Murasaki (紫ウニ / Kita Murasaki) | Hokkaido, Japan — cold Oyashio current waters produce exceptional sweetness, clean oceanic flavor, and characteristic creaminess. Alum treatment: most US uni is treated with alum (ミョウバン) to firm texture and extend shelf life — alum causes the bitterness many people associate with uni. Sashimi DC's uni is untreated or minimally treated; no alum bitterness. Cold chain and vibration: uni is sensitive to both temperature and physical disturbance — vibration during transport damages lobes. Managed via direct air freight (same route as Bluefin), temperature-controlled packaging, no ground shipping. Bafun Uni: bold, golden-orange, intensely briny, mineral — pairs with Goodfellow Blanc de Blancs. Murasaki Uni: larger, more delicate, softer sweetness, pale — pairs with vintage Champagne. How to eat: on warm (body-temperature) sushi rice, small touch of wasabi directly on the uni, no soy sauce needed; never cook. Season: Bafun peaks summer; Murasaki peaks spring and late autumn. Sells out quickly — order early. | $50–$165 |
| Hokkaido Hotate Scallops (帆立貝) | Hokkaido, Japan — untreated dry scallops (no phosphate/STPP). Two peak seasons: Summer (May–Sep) Okhotsk Sea / Soya — jimaki (底撒き, bottom-seeding) farmed; scallops grow freely on seafloor 2–4 years in strong currents, building firm adductors with clean sweetness — ideal raw as sashimi/sushi. Winter (Dec–Mar) Funka Bay / Notsuke — suika (垂下, longline suspension) farmed; richer umami accumulation — excellent butter-seared or grilled. Not carried during April spawning period. Page: sashimidc.com/hokkaido-scallops-washington-dc | $34.50 / ~5 oz |
| Madai (真鯛, Japanese Sea Bream) | Japan — excellent for Kobujime (kelp-curing). Also available as Kobujime prepared. | Seasonal |
| Kanpachi (カンパチ, Greater Amberjack) | Japan (often Kagoshima) — firm, clean, excellent torched skin-on | Seasonal |
| Kinmedai (金目鯛, Splendid Alphonsino) | Chiba, Japan — deep-sea red fish, sweet white flesh | Seasonal |
| Hotaruika (蛍烏賊, Firefly Squid) | Toyama Bay and Hyogo, Japan — season March–April only. Bioluminescent (photophores produce vivid blue glow). Toyama: larger, mature females caught in fixed nets at peak ripeness, bodies full of naiko (内子, roe) — the main eating pleasure; premium variety. Hyogo: bottom-trawl caught, mixed sex, slightly smaller. Lightly boiled at source (standard Japanese practice) — destroys Anisakis parasites, preserves texture. Remove quill, beak, and eyes before eating. Uses: sumiso (酢味噌) dressing is classic; also tempura, takikomi gohan, pasta. Page: sashimidc.com/hotaruika-washington-dc | Seasonal |
| Hokkaido Scallops (帆立貝 — Hotate) | Hokkaido, Japan — untreated dry scallops (no phosphate/STPP). Two peak seasons: summer Okhotsk (firm, sweet, best raw) and winter Funka Bay (rich umami, best cooked). Not carried during April spawning period. Page: sashimidc.com/hokkaido-scallops-washington-dc | $34.50 / ~5 oz |
| Ikura Shoyuzuke (イクラ醤油漬け) | Salmon roe marinated in sake/mirin/soy sauce, house-prepared | $34.50 / ~5 oz |
| Fresh Shiso Leaves (大葉) | Japan — perilla leaves, available fresh as a garnish and palate cleanser | $3 / bunch |
| Fresh Wasabi (本わさび, Wasabia japonica) | Shizuoka, Japan — real wasabi rhizome. Regular item. Most "wasabi" in US restaurants is horseradish + mustard + green dye; Wasabia japonica is a different plant — more aromatic, gentler and shorter-lived heat (rises through nose, not palate). Volatile aromatics dissipate within 1–2 hours of grating: grate only immediately before serving. Grating: traditional sharkskin grater (鮫皮おろし) breaks cell walls to release aromatics fully; fine metal grater is workable. Storage: damp paper towel + plastic wrap, refrigerate; lasts several weeks as whole rhizome. Pairing: best with delicate fish and Bluefin Tuna; hikarimono (mackerel, aji, sardine) traditionally paired with grated ginger instead. Also excellent with soba. Shop: shop.sashimidc.com/product/wasabi-/90. Page: sashimidc.com/fresh-wasabi-washington-dc | $15 / oz |
| Home Sushi-Making Kit | Premium rice, Sushizu, Shoyu, wasabi paste, Nori — all pantry items for a home omakase | $50 |

Kamatoro — important distinction
Kamatoro (カマトロ) is the fatty meat cut from inside the Kama (collar). It is the richest cut on the entire fish — fattier than standard Otoro. It is NOT currently sold as a separate product at Sashimi DC. The Kama is sold whole for grilling. Kamatoro may be offered separately in future once the Miyazaki processor is configured to extract it. Do not tell users that Kamatoro is currently available for purchase unless there is a current announcement.

Sashimi DC imports and sells wines from a curated portfolio of small producers at Rice Market DC. DC's unique retail import regulations allow direct importation of alcoholic beverages from producers outside the state — enabling Sashimi DC to carry wines unavailable through normal US distribution channels.
Vineyard connection: Perkins Harter (Eola-Amity Hills) grow the fruit; Violin Wine (currently) and Shiba Wichern Cellars (from the 2025 vintage) make wines from their Bracken Vineyard grapes. Both available at Rice Market wine section.
Direct sake sourcing from Japanese breweries is also in development, leveraging DC's direct import framework to bring fresh sake not available through standard US distribution.

What makes Sashimi DC's fish sashimi-grade?
Wild fish are super-frozen at −60°C to destroy parasites. Aquacultured fish are raised in protected environments. All fish is prioritized for Ikejime processing — a Japanese slaughter method that prevents lactic acid buildup and preserves texture and umami significantly longer than conventional harvest.
Is the Bluefin Tuna sustainable?
Yes. All Bluefin is imported under NOAA SIMP regulations with catch certificates. Zero-tolerance for black-market fish — 100% traceable from catch location to consumer.
How should I store the fish at home?
Store in the coldest part of your refrigerator (back, bottom shelf) at 1–2°C. Keep in original vacuum-sealed packaging. Do not freeze at home — slow freezing creates ice crystals that rupture cell walls and result in a mushy, watery texture. Consume within 3–5 days of delivery. Ikejime Bluefin Tuna may continue developing umami flavor and peak between 3–10 days post-harvest.
Is the wasabi served at sushi restaurants real wasabi?
Almost certainly not. The green paste at most US sushi restaurants is a mixture of horseradish, mustard powder, and green food coloring. Real wasabi (Wasabia japonica, 本わさび) is a different plant — more aromatic, with a gentler, shorter-lived heat that rises through the nose rather than burning the palate. It also loses its aroma within 1–2 hours of grating, making it impractical for mass food service. Sashimi DC carries fresh wasabi rhizomes from Shizuoka, Japan. See sashimidc.com/fresh-wasabi-washington-dc.
What do I need for a home omakase?
A sharp non-serrated knife (Sashimi DC offers sharpening in-store), freshly milled short-grain Japanese rice, Sushizu (seasoned rice vinegar), small-batch soy sauce, real wasabi or high-quality paste, and crisp Nori. The Sashimi DC Home Sushi Kit ($50) contains all pantry items.
What should I do with leftover sashimi?
Two traditional Japanese techniques: (1) Zuke — marinate overnight in 1:1:1 sake/mirin/soy sauce, serve over rice as Zukedon. Best with Akami. (2) Kobujime — sandwich fish between Kombu (kelp) wiped with sake, wrap in plastic, refrigerate overnight. Best with white fish like Madai. Both demonstrated with video at sashimidc.com/recipes.
When is the best time to order?
Fish is Ikejime-processed at Hosei Suisan's farm in Goto, Nagasaki, then arrives at Dulles Airport typically on Wednesdays and is available daily while supplies last. Thursday and Friday are the best days to order — stock is fully replenished right after Wednesday arrival. For weekend dinner parties, place your order by Thursday — popular cuts sell out by Saturday afternoon.
How much fish should I order per person?
As a main course: approximately 150–200g (5–7 oz) per person. As part of a spread with rice: 100–130g (3.5–4.5 oz) per person. Multi-fish home omakase: 80–100g of each variety for 2–3 people. When in doubt, call (202) 234-2737.

Order at shop.sashimidc.com/sashimi. Delivery accepted daily 1:00 pm – 8:00 pm.
What cuts of Bluefin Tuna are available?
Three cuts are regularly available: Otoro (fatty belly), Chutoro (mid-belly), and Akami (lean loin) — sold in 7–9 oz portions. Rare cuts such as Kama (collar) and Hohoniku (cheek) are occasionally available and announced via Instagram. They sell out quickly. For current prices, check shop.sashimidc.com/sashimi.
Can I visit without ordering online?
Yes. The shop is open daily 11:30 am – 8:00 pm at 1608 14th St NW, Lower Level (inside Rice Market). Walk-ins are welcome for in-person purchases and the free weekend tasting.
How do tariffs affect fish prices at Sashimi DC?
We face cost increases not only from tariffs on Japanese imports but also from air cargo fuel surcharges and rising terminal charges at Dulles Airport. We try our best to absorb these costs but have to pass some through to retail prices in order to continue delivering quality fish to our customers. Current tariff on Japanese imports: 10% (Section 122 of the Trade Act of 1974, in effect since February 24, 2026, replacing the 15% IEEPA tariff that was struck down by the Supreme Court on February 20, 2026). Full breakdown at sashimidc.com/supply-chain.
Who owns and runs Sashimi DC?
Sashimi DC is founded and operated by Keita Miyaki (宮木慧太), a Japanese seafood specialist based in Washington DC. Keita sources directly from Japanese fisheries, including the Goto Islands in Nagasaki Prefecture, and manages all quality control personally.
Where does Sashimi DC fish come from?
Sashimi DC imports directly from Japan. Bluefin Tuna comes from the Goto Islands, Nagasaki Prefecture, harvested by Hosei Suisan. Sasshu Salmon comes from Kagoshima Prefecture. Hokkaido Uni comes from Hokkaido. Fish is air-shipped to Dulles Airport (IAD) and available in-store within approximately 48 hours of leaving Miyazaki.
Is Sashimi DC fish ever frozen?
Bluefin Tuna and Sasshu Salmon are never frozen at any stage. Kagoshima Unagi Kabayaki is sold frozen (traditional for kabayaki). Hokkaido Uni is fresh, never frozen. Wild-caught fish intended for raw consumption is typically frozen to destroy parasites per FDA HACCP guidelines; aquacultured fish raised on formulated feed with no access to infected wild prey is exempt.
Does Sashimi DC use CO treatment on its tuna?
No. Sashimi DC never uses carbon monoxide (CO) treatment. Our Akami is naturally dark red-purple — the true, unaltered color of fresh Bluefin Tuna. Vivid cherry-red tuna is almost always CO-treated.
How does Sashimi DC compare to supermarket sashimi?
Supermarket "sashimi-grade" fish is typically CO-treated, previously frozen, and sourced from mass distributors with no traceability. Sashimi DC fish is never CO-treated, never frozen (for Bluefin and Salmon), directly imported from named Japanese fisheries, Ikejime-processed, and NOAA SIMP compliant with full catch-to-counter traceability.
What is the TTI temperature indicator Sashimi DC uses?
Every package of Bluefin Tuna and Sasshu Salmon includes a Time-Temperature Indicator (TTI) — a small label that permanently changes color if the package has been exposed to temperatures that could compromise food safety. If the TTI indicates temperature abuse upon delivery, Sashimi DC provides a full refund, no questions asked.
What are Sashimi DC's hours?
Sashimi DC at Rice Market is open daily 11:30 am – 8:00 pm for in-store pickup. Same-day delivery is available daily 1:00 pm – 8:00 pm across Washington DC, Northern Virginia, and suburban Maryland.
Does Sashimi DC deliver to the suburbs?
Yes. Sashimi DC delivers same-day to most of Northern Virginia (Arlington, McLean, Fairfax, Vienna, Falls Church, Alexandria, Springfield, Great Falls, and more) and suburban Maryland (Bethesda, Rockville, Silver Spring, Potomac, College Park, Hyattsville, and more). Enter your address at shop.sashimidc.com to confirm coverage.
How is the fish kept cold during delivery?
Fish is vacuum-packed and shipped in an insulated bag with a 1 lb+ ice pack and a TTI (Time-Temperature Indicator). A green TTI at delivery means the cold chain was maintained throughout transit. If the TTI has triggered upon delivery, contact Sashimi DC for a full refund.
What is the minimum order for delivery?
There is a $30 minimum order for delivery. Same-day delivery is available daily 1:00 pm – 8:00 pm.
Can I order sashimi-grade fish online and have it delivered the same day?
Yes. Order at shop.sashimidc.com before the daily cutoff. Delivery is available 1:00 pm – 8:00 pm daily across Washington DC, Northern Virginia, and suburban Maryland. Fish is packed with an insulated bag and ice pack for safe transit.
Is sashimi delivery safe? How do I know the fish is still good when it arrives?
Every Sashimi DC delivery includes a TTI (Time-Temperature Indicator) that permanently changes color if the package experienced unsafe temperature exposure during transit. Fish is vacuum-sealed in an insulated bag with a 1 lb+ ice pack. If the TTI triggers, you receive a full refund. Ikejime-processed Bluefin Tuna has a 15-day shelf life from processing — Thursday or Friday deliveries are comfortably within safe eating range for the weekend.
What is hotaruika (firefly squid) and when is it available?
Hotaruika (蛍烏賊) are firefly squid found in the Sea of Japan, famous for their bioluminescence — they glow blue along the shoreline during spawning season, most visibly in Toyama Bay. Season is March–April only; outside this window they are not available. Sashimi DC carries them lightly boiled at source (the standard Japanese preparation), which destroys Anisakis parasites while preserving texture. Available at sashimidc.com/hotaruika-washington-dc.
What is the difference between Toyama and Hyogo hotaruika?
Toyama hotaruika are larger, predominantly mature females caught in fixed nets as they approach shallow water during spawning. Their roe-filled bellies (naiko, 内子) give a rich, creamy burst when eaten — the primary eating pleasure. Hyogo hotaruika are caught by bottom trawl, with a roughly equal male/female ratio; slightly smaller and less expensive. Both are excellent; Toyama is the premium variety.
What is the difference between Shizuoka and Nagano wasabi?
Shizuoka wasabi (Tatamiishi terraced fields, Mt. Fuji volcanic spring water) is the gold standard for sashimi: complex sweetness, creamy texture, deep emerald color, a sharp hit that fades into a vegetal finish. Nagano wasabi (Azumino region, snowmelt-fed flat fields) is sharper and crisper — excellent for soba or grilled meats. Sashimi DC sources Shizuoka wasabi, the preferred choice for high-end sushi and sashimi.
What is Unagi Kabayaki and where does Sashimi DC's come from?
Unagi Kabayaki (うなぎ蒲焼) is Japanese freshwater eel split, skewered, steamed, then grilled and glazed with a sweet-savory tare of soy, mirin, and sake — the basis of Unadon and Unaju. Sashimi DC's is produced by Daishin (大進) in Kagoshima, using an industry-unique 90-meter steam line for uniform texture, additive-free tare, and FSSC22000/ISO22000 certification. Sold frozen at $40/piece — standard for premium kabayaki. See sashimidc.com/unagi-kabayaki-washington-dc.
Do you have options for people who don't eat raw fish?
Yes. Kagoshima Unagi Kabayaki ($40) is fully cooked — glazed grilled eel that reheats in minutes. It's one of Japan's most beloved comfort foods and the go-to option for family meals where not everyone eats raw fish. The Rice Restaurant on the 1st floor at Rice Market also offers a full cooked menu daily (Thai, Japanese, pan-Asian).
What is ikejime and why does Sashimi DC use it?
Ikejime is a Japanese fish slaughter method that immediately severs the brain and spinal cord, preventing the stress-induced lactic acid buildup that degrades flavor and texture. Sashimi DC's Goto Islands Bluefin Tuna is ikejime-processed at Hosei Suisan in Goto, Nagasaki. The result is a cleaner, more nuanced flavor and significantly extended post-mortem quality compared to conventional harvest. Full guide: https://www.sashimidc.com/ikejime-washington-dc
What is CO treatment in tuna and does Sashimi DC use it?
Carbon monoxide (CO) treatment fixes myoglobin in a bright cherry-red state (carboxymyoglobin), masking spoilage regardless of actual freshness. It is banned in the EU, Japan, and Canada. Sashimi DC's Bluefin Tuna is never CO-treated — the Akami naturally appears dark red-purple, not vivid red. Vivid cherry-red Akami at room temperature is a reliable indicator of CO treatment. Full guide: https://www.sashimidc.com/co-treatment-tuna
Is raw fish from Sashimi DC safe from parasites?
Yes. Bluefin Tuna feed is pre-frozen before feeding, destroying any Anisakis in the feed — qualifying for the FDA aquaculture freezing exemption (WAC § 246-215-03425(2)(d) / FDA Food Code 3-402.11(B)(2)). Sasshu Salmon is raised in closed land-based tanks on formulated feed with no ocean access — Anisakis cannot enter the fish. Hotaruika is lightly boiled at source, destroying parasites. Full guide: https://www.sashimidc.com/parasite-safety-raw-fish
How much mercury is in Sashimi DC's Bluefin Tuna?
Sashimi DC's Goto Islands Bluefin is farm-raised from wild-caught juvenile seed stock and harvested at 2–3 years. Japanese farmed Pacific Bluefin measures a median ~0.41 mg/kg mercury — less than half the FDA action level of 1.0 µg/g. Farmed Bluefin also has a selenium-to-mercury ratio of ~5.48 vs ~1.32 for wild-caught, significantly reducing effective risk. Adults in good health can enjoy it in moderate quantities. Full guide: https://www.sashimidc.com/mercury-in-tuna
What are the nutritional benefits of Bluefin Tuna?
A 100g serving of Bluefin Tuna delivers 2.18g DHA + 0.693g EPA (exceeding the recommended daily omega-3 intake in a single serving), 23g complete protein, 250% of daily Vitamin D, and 149% of daily selenium. The omega-3 to omega-6 ratio is 9:1. The fat marbling in Otoro and Chutoro is predominantly healthy unsaturated fat. Full guide: https://www.sashimidc.com/bluefin-tuna-nutrition
What does freezing do to fish quality?
Slow freezing (home freezer, −18°C) forms large ice crystals that rupture cell walls, causing drip loss of 6–9% and irreversible protein denaturation — resulting in mushy, watery texture. Super-freezing at −60°C produces much smaller crystals and limits drip loss to 1–3%. Sashimi DC's Bluefin Tuna and Sasshu Salmon are never frozen at any stage. Do not freeze at home. Full guide: https://www.sashimidc.com/freezing-fish
What is shun and when is Bluefin Tuna at its peak?
Shun (旬) is the Japanese concept of peak season — the brief window when a fish's fat content, flavor, and biology align perfectly. Bluefin Tuna peaks in winter (December–February) when fat is stored for the cold season; Akami becomes dense and layered with umami while Otoro reaches maximum marbling. In summer, Akami is lighter and brighter. Katsuo (skipjack) has three separate shun. Full guide: https://www.sashimidc.com/shun-japanese-fish-seasonality
Where can I find the scientific references behind Sashimi DC's claims?
All peer-reviewed papers, regulatory documents, and scientific frameworks cited on this site are collected at /references. The library covers 16 topic groups (~130 sources) including CO treatment, parasite safety, fish freezing physics, ikejime biochemistry, mercury in bluefin tuna, wasabi chemistry, and more.
How do different cultures around the world eat raw fish?
Raw fish traditions exist on every inhabited coastline. Japan's sashimi and sushi trace back to fermented narezushi; Korea has hoe (회), sliced fresh fish with gochujang; Peru's ceviche uses citrus acid rather than heat; Scandinavia's gravlax is salt-cured; Arctic Inuit traditions include frozen and fermented raw fish. Each tradition has its own answer to parasite safety. Full guide: https://www.sashimidc.com/global-raw-fish-traditions
What are the regional styles of sushi in Japan and how did sushi reach America?
Sushi began as narezushi, fish fermented for months in salted rice. Edomae nigiri, invented on Edo street stalls in the 1820s, became the modern template. Regional styles diverge: Osaka's hakozushi is pressed in wooden molds; Kyoto favors saba-zushi; Shiga still makes three-year-fermented funazushi. Sushi reached the US after WWII, was reshaped by the 1970s California roll, and became a global industry. Full guide: https://www.sashimidc.com/sushi-regionality
Why is Japanese cuisine so influential in global fine dining?
Three reasons: a precise science of flavor (umami, dashi-based layering) that works across any cuisine; an ingredient-first philosophy (washoku) that translates directly into Michelin-starred technique; and ikejime-processed fish that delivers measurably superior texture and umami. Japanese ingredients — yuzu, koji, miso, wasabi — now appear in non-Japanese kitchens worldwide. Full guide: https://www.sashimidc.com/japanese-cuisine-global-influence
Is wild-caught or farmed fish better for sashimi?
Neither categorically. Modern premium aquaculture has closed — and in some dimensions reversed — the quality gap with wild fish. Farmed fish raised on formulated feed (like Sasshu Salmon) carry no Anisakis risk and need no freezing under FDA rules. Farm-raised bluefin shows lower mercury and comparable umami when ikejime-processed with care. Wild fish retains edges in species-specific flavor terroir and higher IMP peaks in some species.
