Transparency · Import Costs · Quality Control
Three cost pressures are hitting every shipment from Japan right now: tariffs, a tripling of air cargo fuel surcharges, and rising terminal fees at Dulles. And behind the numbers: a direct look at how quality is controlled when you own the relationship with the processor — from color deviations caught overnight to cold chain management at IAD.

To understand why the supply chain model at Sashimi DC is unusual, it helps to know what the typical American seafood supply chain looks like. The United States imports approximately 75–90% of the seafood it consumes. The conventional import chain runs through at least five or six layers: farmer or fishery, processor, exporter, importer, distributor, and finally retailer. Each layer adds transit time, temperature transitions, and margin — and none of them owns quality as a primary concern.
NOAA's seafood inspection program is voluntary. Most processors do not participate. There is no mandatory federal grading system for fresh fish quality, only safety floors. A 2024 meta-analysis in Food Control found a 39.1% overall mislabeling rate across US seafood samples — meaning the fish on the label is often not the fish in the package. For premium fish eaten raw, these are not abstract concerns.
Sashimi DC's chain is roughly half that length: farmer and processor in Japan deal directly with the retailer in Washington DC, with no exporter, importer, or distributor in between. The fish moves faster, fewer hands touch it, and — critically — there is a direct communication line to fix problems at source. The cost section below shows what that model actually costs to operate in 2026.
Every shipment of fish from Japan to Washington DC passes through the same chain: air freight from Fukuoka or Haneda to Dulles (IAD), customs clearance with applicable duties, and terminal handling at the cargo facility. Each of the three legs has gotten meaningfully more expensive over the past year, and all three are operating at the same time.
This page explains each one factually, with the actual numbers. It is not a complaint — cost volatility is part of operating a direct-import business — but transparency about what is happening seems more useful than silence.
The tariff situation on Japanese imports has changed four times since April 2025 and is still not fully resolved. The short version: there was a 15% tariff on Japanese goods from August 2025 through late February 2026, then the Supreme Court struck down the legal basis for it, and a 10% replacement tariff is currently in effect under a different statute.
CBP launched CAPE (Consolidated Administration and Processing of Entries) on April 20, 2026 — a system to process refunds of duties paid under the now-invalid IEEPA tariffs. Phase 1, which went live on April 20, covers unliquidated entries and entries liquidated within the prior 80 days, estimated at roughly 63% of affected entries. Phase 2, covering older liquidated entries, has not yet been announced. Refunds for accepted CAPE declarations are expected within 60–90 days.
Import cost impact — tariffs. The current 10% Section 122 surcharge applies to the full declared customs value of each shipment — fish plus packaging. The 15% IEEPA rate that applied August 2025–February 2026 added 50% more duty than the current rate. The 10% Section 122 rate is the same as the pre-negotiation baseline that was in effect during the April–August 2025 pause.
Fish travels on ANA Cargo flights from Fukuoka or Haneda to Dulles. The fuel surcharge is set by ANA Cargo and revised monthly — or since April 2026, semi-monthly — based on the Singapore Jet Kerosene (Platts) index. The surcharge applies to the entire shipment weight including packaging and ice packs.
The surcharge was relatively stable throughout 2024 and 2025, ranging between ¥64 and ¥106/kg. It held in the ¥71–85/kg band from mid-2025 through the end of Q1 2026. Then in April 2026 it moved sharply: from ¥78/kg on April 1 to ¥247/kg on April 16 — a tripling in two weeks. It has since eased slightly to ¥226/kg from May 1, but remains at historically high levels.

Import cost impact — fuel surcharge. A typical bluefin shipment weighs 100–120 kg including packaging and ice. At the April 16 rate of ¥247/kg versus the ¥78/kg rate in effect on April 1, the fuel surcharge increase alone adds approximately ¥16,900–20,300 per shipment. At current exchange rates that is roughly $110–135 more per shipment in fuel cost versus two weeks prior.
Every air waybill (AWB) cleared through the cargo terminal at Dulles carries a handling fee. This has risen significantly since 2024 — and the structure of the charge has become more complex. In 2024, there was a single processing fee of $10 on top of the base terminal charge. The current bill includes the base terminal charge plus a processing fee, a credit card fee, and a convenience fee — different charges added over time, now totaling $37.98 in fees on top of the base rate.

The terminal charge has risen 55% from the 2024 baseline — from $150 to $232.98 — in roughly two and a half years. Part of this is inflation; part is the layering of new fee categories. The practical effect is the same either way: a higher fixed cost on every shipment regardless of fish weight or value.
These three costs operate independently and compound. A shipment arriving in late April 2026 faces all three simultaneously: the 10% Section 122 tariff on declared value, a fuel surcharge at roughly three times the Q1 level, and terminal handling costs that have more than doubled since 2024. None of these is within our control. What we can control is how honestly we account for them.
Import cost drivers — April 2026 vs. baseline
Some of these cost increases are absorbed — margin compression is an unavoidable part of operating in a volatile import environment. Some portion is passed through to retail prices. We will not pretend otherwise. When prices change, it is because the underlying import cost has changed, not arbitrarily.
The tariff situation in particular remains fluid. The Section 122 surcharge runs to approximately mid-July 2026 unless extended by Congress. IEEPA refunds through the CAPE system are pending for eligible entries. Fuel surcharges are revised every two weeks and can move quickly in either direction. We will update this page as the situation develops.
Against all of the above cost pressure, one thing has not changed: the sourcing. Every shipment still comes directly from Japan — Goto Islands bluefin, Kagoshima salmon and unagi, Hokkaido uni — processed at source using the same ikejime method, never frozen, arriving at Dulles within approximately 48 hours of leaving Miyazaki.
That authenticity is now recognized formally by the Japanese government. Sashimi DC holds certification as a Japanese Food and Ingredient Supporter Store (ID: J000-001-410, valid May 2026 – May 2028) under guidelines issued by Japan's Ministry of Agriculture, Forestry and Fisheries (MAFF) and administered by JETRO (Sashimi DC listing). The program certifies overseas retailers that consistently sell authenticated Japanese-origin seafood and accurately represent their provenance. Sashimi DC is one of two certified establishments in Washington DC — the other is Sushi Taro, one of the city's most established Japanese restaurants — and the only certified fish retail counter in the city.
The value of a short supply chain is not just speed. It is the ability to communicate directly with the processor when something is off — and to get it fixed. In a conventional import chain with five or six intermediary layers, a quality observation made at the retail counter in Washington DC would need to travel back through a distributor, an importer, and an exporter before reaching the source. By that point the batch is sold, the fish is gone, and nothing changes.
With a direct relationship, the conversation is one step. The following are real examples of problems caught and corrected through that channel.
Chutoro · Color
One batch of Chutoro arrived with the white marbling intact but the surrounding pink flesh looking duller than usual — not off in flavor or texture, but visually below standard. Keita flagged it to the processor directly.
The cause was identified within hours: Hiyashikomi — the post-harvest icing protocol — had not been applied as rigorously as standard that week. The processor corrected the protocol immediately. The same issue has not recurred.
Packaging · Cold Chain
Moving into warmer months, the processor tested a heavier absorbent sheet inside the oxygen-reduced packaging to manage higher moisture levels during transit. It worked too well — the sheet pulled moisture out of the fish itself, affecting texture.
Keita identified the cause and communicated it back. The processor reverted to the standard sheet. The test had been a reasonable adaptation; the feedback loop made it correctable before it became a pattern.
Saku Blocks · Consistency
In the early months of the direct import relationship, the processor was cutting Saku blocks for the first time to Keita's specifications. Weight variance was significant — customers occasionally received pieces meaningfully larger or smaller than advertised.
Keita raised the issue; the processor standardized their cut weights. Variance is now consistent and within a tight range. This kind of calibration only happens when you can speak to the cutter directly.
Chutoro · Texture
Through direct dialogue in early 2026, the Senaka cut was adjusted so that Chutoro blocks now contain fewer sinews — producing smoother texture across the piece. This was not a problem report; it was a quality refinement identified through ongoing communication.
Small improvements like this compound over time. They happen because Keita can message the QA manager overnight and receive a response by morning — not file a ticket with a distributor.
Packaging · Logistics
One shipment arrived at IAD with a cracked Styrofoam box — almost certainly dropped during cargo handling. TTI indicators and unmelted ice packs confirmed the fish condition was unaffected, but the structural failure was documented and communicated to the processor.
They responded by adding reinforcement tape around the body of each box — not just the standard lid-sealing tape, but structural tape running around the full perimeter for robustness. Every shipment since has arrived intact.
Cold Chain · Air Freight
Pet animals sometimes travel on the same ANA flights as fish shipments, and are held in an air-conditioned cargo room to protect them. Keita identified that fish held in the same heated room would face unnecessary temperature risk.
Working through ANA OCS (the forwarding agent), a standing instruction was added to hold the fish shipment in a separate, unheated cargo room — maintaining cold chain integrity from Japan to the IAD cargo counter where Keita picks up every shipment personally.
What this actually means. Every one of these improvements was only possible because there is a direct line of communication to the processor. None of them required a formal complaint process, a distributor escalation, or waiting for the next shipment cycle. Quality improvement in a direct-import model is iterative and fast. That is the structural advantage — not just fewer layers, but faster learning.
The supply chain conditions change. The sourcing does not — still direct from Goto, Kagoshima, and Hokkaido, still never frozen, still in Washington DC within approximately 48 hours of Miyazaki processing.
As of late February 2026, Japanese imports — including fish — are subject to a 10% surcharge under Section 122 of the Trade Act of 1974. This replaced the 15% IEEPA-based tariff that was in effect from August 2025 through February 24, 2026, after the Supreme Court ruled in Learning Resources, Inc. v. Trump (February 20, 2026) that IEEPA does not authorize the President to impose tariffs. Section 122 tariffs are capped at 15% and limited to 150 days unless extended by Congress.
ANA Cargo's fuel surcharge is tied to the Singapore Jet Kerosene (Platts) index. The rate had been stable at roughly ¥71–85/kg throughout 2025 and into early 2026, then tripled — rising from ¥78/kg on April 1 to ¥247/kg on April 16. This reflects a sharp movement in jet fuel markets. ANA also switched from monthly to semi-monthly revision cycles starting April 2026 to track the market more closely. The May 1 rate eased slightly to ¥226/kg.
Possibly, for some entries. CBP launched CAPE (Consolidated Administration and Processing of Entries), a refund system for IEEPA duties, on April 20, 2026. Phase 1 covers unliquidated entries and those liquidated within the prior 80 days — approximately 63% of affected entries. Phase 2, which will cover older liquidated entries, has not yet been announced. Refunds, when approved, are expected within 60–90 days of CAPE declaration acceptance.
Yes, in part. The tariff, fuel surcharge increase, and terminal fee increases all add to the per-shipment cost of imports. Some of that increase is absorbed; some is passed through to retail pricing. When prices change, it is because the underlying import cost has changed. We try to be transparent about what is driving cost changes rather than adjusting prices without explanation.
The Section 122 tariff has a 150-day limit from its implementation on February 24, 2026 — running to approximately mid-July 2026. At that point Congress must extend it or it expires. Whether a longer-term trade agreement between the US and Japan will be negotiated before then is uncertain. We will update this page as things change.
Yes. Sashimi DC is certified as a Japanese Food and Ingredient Supporter Store by Japan's Ministry of Agriculture, Forestry and Fisheries (MAFF), administered by JETRO (ID: J000-001-410). The program certifies overseas retailers that consistently sell authenticated Japanese-origin seafood and accurately represent its provenance. Sashimi DC is one of two certified establishments in Washington DC and the only certified fish retail counter in the city. Sashimi DC listing.
Because the import is direct — no exporters, importers, or distributors between the processor in Miyazaki and the counter in DC — Keita can message the QA manager overnight and receive a response by morning. Documented examples: a color deviation in Chutoro traced to insufficient post-harvest icing (corrected immediately); an absorbent sheet pulling moisture from the fish (reverted within one shipment cycle); Saku block weight variance (standardized after direct communication in the early months). Each problem was identified at the retail counter and fixed at the source.
Our Akami is naturally dark red-purple — the true, unaltered color of fresh Bluefin Tuna. Much of the vivid cherry-red tuna sold elsewhere has been CO-treated: carbon monoxide reacts with myoglobin to lock in bright color regardless of actual freshness. CO treatment is banned in Japan, the EU, and Canada; permitted in the US. Because we monitor color closely through direct processor communication — the Hiyashikomi incident is a documented example — we know what correct, untreated color looks like and flag any deviation before it reaches the customer.
Fish is packed with ice packs (quantity adjusted seasonally — more in summer) and a TTI (Time-Temperature Indicator) that records any temperature excursion in transit. At IAD, Keita picks up every shipment personally from the ANA Cargo counter. A standing instruction with ANA OCS (the forwarding agent) holds the fish in an unheated cargo room — separate from the air-conditioned room used for pet animals on the same flights. Boxes are reinforced with structural tape after a cracked Styrofoam box incident. Temperature abuse on delivery triggers a full refund.
Yes. All Bluefin Tuna imported by Sashimi DC complies with NOAA's Seafood Import Monitoring Program (SIMP) — a US federal regulation requiring full catch documentation at every step: vessel name, fishing area, gear type, and catch date. SIMP is a compliance requirement, not a voluntary certification. The result is 100% traceable from ocean to the counter in DC, with zero tolerance for black-market or illegally sourced fish.
Ikejime (活け締め) is a Japanese slaughter technique involving three core steps: brain spiking (instant neural death), exsanguination (bleeding out), and shinkei-jime (spinal cord destruction via wire). Together these stop stress hormones and anaerobic glycolysis immediately after death, preserving the fish's ATP reserves at their maximum level.
ATP matters because it is the direct precursor to IMP (inosine monophosphate) — the primary umami compound in fish muscle. Post-mortem, ATP degrades through a cascade: ATP → ADP → AMP → IMP → inosine → hypoxanthine. In a conventionally slaughtered fish, ATP is already depleted from stress and thrashing before the cascade begins, so IMP never accumulates meaningfully. In an ikejime-processed fish, ATP starts high — the IMP peak is greater, lasts longer (typically days 3–10 post-harvest for Goto Bluefin), and the fish improves during that window rather than declining. The lactic acid from stress slaughter also lowers muscle pH, softening texture and impairing water-holding capacity; ikejime prevents this entirely.

High-quality sashimi-grade Bluefin Tuna and Salmon are not available from local suppliers regardless of price — so the real comparison is against other import channels. Because Sashimi DC is both importer and retailer, tariff increases pass through with only one margin layer added. In a conventional chain of importer → distributor → retailer, each layer prices on its input: the same base cost compounds from $100 × 1.2³ = $172.80 to $110 × 1.2³ = $190.08 — a $17.28 increase from the same $10 tariff. Tariffs affect every import channel; the more layers, the more the increase compounds.
