Japanese eel (うなぎ / Unagi) is the soul ingredient at the pinnacle of Japanese cuisine: the aromatic allure of Kabayaki, the fresh purity of Shira-yaki, and the refined elegance of Hitsumabushi—all built upon rigorous quality control of origin, specifications, processing, and cold chain. For Michelin's eel restaurants, yakitori specialists, and high-end Omakase establishments in Macau, a stable eel supply chain is essentially the lifeline of their menu signatures. From the B2B supply perspective of Inari Global Foods, this article deconstructs the four key dimensions of Japanese eel procurement and compares the coverage differences with competitors (Global Seafood / Eat First) based on publicly available information.
1. Overview of Japan's Three Major Eel Production Regions
Japan's eel industry is concentrated in central-southern Honshu and Kyushu, with three major production clusters differentiated by water quality, farming scale, and maturation techniques:
- Aichi Prefecture, Nishio City — Issho Town: Japan's largest eel production region (according to Japanese Ministry of Agriculture, Forestry and Fisheries e-Stat public data). The Mikawa Bay freshwater confluence and geothermal spring water enable year-round farming, with average fat content of 18-22% in the meat, producing golden-colored grilled eel (kabayaki).
- Kagoshima Prefecture, Osumi Peninsula: Volcanic rock groundwater farming in the south with slightly acidic water quality. Eels mature approximately 8 weeks faster than in Aichi, resulting in firmer flesh ideal for white-grilled (shirayaki) preparations that showcase the pure flavor.
- Shizuoka Prefecture, Lake Hamana: The birthplace of Japanese eel farming (1900s). Although production volume is lower than Aichi in recent years, "Lake Hamana Eel" commands significant brand premium, and historic kabayaki specialty shops (such as "Unazen" and "Yaohontoku") specifically source from this region.
Beyond these three major regions, Miyazaki, Kochi, and Chiba also have commercial-scale farms. Japan's total annual eel production is approximately 15,000 metric tons, with 60% consumed domestically. Export-available quota (including B2B wholesale) is limited, leading to intense competition among importers in the Macau market.
2. Grade Classification: Kabayaki vs Shira-yaki vs Fresh
B2B procurement portals typically feature three processing types:
| Type | Processing Method | Specifications | Typical Uses |
|---|---|---|---|
| Kabayaki (かばやき) | Skewered, brushed with soy sauce and mirin, repeatedly grilled until caramelized | 180-220g / 250-280g / 300-350g | Unadon, Hitsumabushi, bento main dish |
| Shira-yaki (しらやき) | Grilled directly without soy sauce, with salt only | 200-300g | High-end Omakase, sake pairing |
| Fresh Live Eel | Live delivery, freshly slaughtered and processed in-kitchen | 250-400g / piece | Michelin-starred eel restaurants, traditional yakitori shops |
Kabayaki accounts for approximately 70% of export volume (finished product is convenient for storage and can be thawed for immediate use), while Shira-yaki and live eel account for approximately 30%. Macau B2B procurement ratio is approximately Kabayaki 75% / Shira-yaki 18% / Live Eel 7%.
3. Dual Cold Chain Lines: -40°C Quick Freeze vs 0-4°C Fresh Ice Transport
Inari Supply Chain follows a dual cold chain design, tailored to customer kitchen SOP configurations:
- Quick-Frozen Unagi Line (-40°C → -18°C maintained): Vacuum-packed at the Japanese factory and instantly quick-frozen at -40°C to lock in the fat, air-freighted to Australia within 48 hours, stored at -18°C in kitchen freezers, shelf life 12 months. 80% of unagi restaurants in Macau use this line.
- 0-4°C Fresh Ice Transport Line (Live Eel / White Grilled): Shipped from Japan at 7:00 AM, arrives in Hong Kong at 17:00, maintained at 0-4°C throughout, 72 hours shelf life. Suitable for Michelin-grade unagi restaurants and Omakase weekend service.
Shipping Frequency: Inari currently maintains 2 weekly eel dedicated cargo flights (Tuesday / Friday), increased to 3 weekly during peak season (July-August). All shipments include JFA (Japan Fisheries Agency) certification and origin traceability QR codes.
4. B2B Procurement Specifications
Typical Macau B2B procurement specifications:
- Standard Unagi Kabayaki: 200g / 280g / 350g in three sizes; 20 pieces/carton, 40 pieces/carton in two packaging options.
- White-grilled Long Cut: Starting from 300g; 10 pieces/carton.
- Live Eel: 250-400g/piece; 20 pieces/barrel (transported in oxygenated water).
- Bundle Side Dish Set: Unagi Kabayaki + Kabayaki Sauce + Sansho Powder + Wooden Box (for ひつまぶし set meal restaurants).
Inari Macau B2B Minimum Order Quantity (MOQ): Starting from 5kg; Monthly contract customers can apply for as low as 2kg.
5. Competitor Coverage Comparison (Global Seafood / Eat First Public Data)
As of Q2 2026 based on public data:
- Global Seafood: Specializing in seafood products, eel is not a core SKU, with only one Aichi prefecture grilled eel variant available, no white-grilled / live eel options.
- Eat First: The wholesale catalog primarily features Chinese eel, with Japanese eel accounting for approximately 25%, with no specific prefecture of origin indicated.
- Inari Global Foods: 100% Japanese origin, covering three major production areas: Aichi / Kagoshima / Hamana Lake, offering full product lines including grilled, white-grilled, and live eel, along with traceability QR codes and JFA certification.
6. Seasonality and Optimal Supply Period
Japanese eel peak season is summer (June-August, aligned with the "Doyō no Ushi" tradition), but farmed eels are available consistently year-round. Winter eels have slightly higher fat content (fat reserves for winter), and are also favored by high-end eel restaurants. Macau B2B procurement recommendations:
- Summer peak season: Confirm quantities 6 weeks in advance; the 2 weeks before Doyō no Ushi (late July) are the cap-out period.
- Winter regular period: Flexible ordering possible; recommended to sign monthly quota contracts to lock in prices.
- During Lunar New Year (January-February): Japanese factories are closed for 7-10 days, restocking needs to be completed by the end of December.
7. Food Safety and Compliance (Macau IAM / IFB)
All Inari eel imports comply with:
- Macau IAM (Instituto de Assuntos Municipais) food safety related regulations and import permits.
- IPIM (Macau Trade and Investment Promotion Institute) food standards.
- Japan JFA certification + shipment certificates by prefecture of origin.
- EU / US similar sustainability standards (such as ASC-Eel) are adopted as much as possible; however, this certification system is still in the development stage.

常見問題 Frequently Asked Questions
What is the Minimum Order Quantity (MOQ) for Inari Macau B2B eel?
Inari Global Foods' standard B2B eel MOQ is 5kg; monthly contract accounts can apply to reduce it to 2kg. The same MOQ applies across all three product lines: kabayaki, shirayaki, and live eel. Request a formal quote via WhatsApp +853-6282-3037.
How do I choose between kabayaki and shirayaki eel?
Kabayaki is suitable for flavorful dishes such as unadon, hitsumabushi, and bento; shirayaki preserves the eel's natural taste, ideal for omakase, sake pairing, and high-end Michelin eel restaurants. We recommend offering both options on your menu to cater to different customer preferences.
Which eel cold chain line suits my kitchen?
If your kitchen has a -18°C freezer and stable daily output, we recommend the quick-frozen kabayaki line (12 months shelf life); for Michelin-level or weekend peak service, the 0-4°C fresh chilled line (live eel/shirayaki, 72 hours shelf life) is recommended.
How should I plan orders during eel peak season?
Summer (June-August) is peak season, with Doyo Ushhi (late July) as the highest point. We recommend securing your quota 6 weeks in advance; monthly contract accounts receive priority allocation. Winter regular season is more flexible; we recommend signing monthly quota contracts to lock in prices.
Does Inari eel have sustainability certifications?
All Inari eel products come with JFA (Japan Fisheries Association) certification and prefecture-of-origin shipping certificates. The eel-specific ASC-Eel certification system is still under development; Inari will continue monitoring and adopting similar sustainability frameworks (such as MSC/EU standards) where possible.
