1. Comparison Overview

Hokkaido Ezo-bafun Uni vs Sanriku Uni: Macau Japanese Cuisine B2B Procurement Conclusion

Procurement Conclusion First

Macau Japanese restaurants should adopt a "dual-line procurement" strategy:

Usage	Recommendation
Omakase / Premium Sashimi / Signature Uni Donburi	Hokkaido Ezo-bafun uni, especially from Rausu, Rishiri, Hamanaka, and Nemuro regions
Daily Gunkan, Rolls, Set Meals, Cost Control	Sanriku Iwate-type Kitamurasaki uni / Salt water uni
Not Recommended	Miyagi Prefecture Nan-Sanriku source, as Macau still maintains a ban on imports of fresh food, animal-derived products, aquatic products and aquatic product preparations from Miyagi and 10 other prefectures

Core Price Difference

Public market and retail/direct-from-producer data shows that Japanese-side prices that Macau restaurants can use as quotation benchmarks are approximately:

Comparison Item	Hokkaido Ezo Bafun Uni	Sanriku Iwate-line Uni	Price Difference Assessment
Premium boxed/loose-packed public price	Approximately ¥33,800-58,000 / 250-300g	Approximately ¥19,800 / 250g or ¥6,200 / 150g	Hokkaido approximately 1.7-3.3 times
Converted per 100g	Approximately ¥11,300-19,300 / 100g	Approximately ¥4,100-7,900 / 100g	Difference ¥3,400-15,200 / 100g
Toyosu "Uni" market daily price reference	2026-05-15: High ¥110,000 / Medium ¥35,000 / Low ¥9,500, unit "one piece"	Same market classification, mixed origin	Premium red uni pushes up the upper limit
Estimated after landing in Macau	Add cold chain, loss, customs clearance, and agent margin per 100g	Same cost addition, but low-price products are more affected by fixed costs	Actual menu cost difference usually remains 40-120%

Distinguish Between Variety and Name

Name	Actual Situation	Restaurant Procurement Implication
北海道エゾバフンウニ	True "red uni", orange in color, rich flavor, strong sweetness, high umami density	Suitable as premium main ingredient
三陸バフンウニ	Often generally called "Sanriku uni" in the market, but about 90% of Iwate's edible catch is キタムラサキウニ, and about 10% is エゾバフンウニ	When procuring, must clarify whether it's "キタムラサキ" or "エゾバフン"
宮城南三陸ウニ	Main publicly available data points to キタムラサキウニ	Macao imports currently have regional risk; Miyagi source should not be used for regular procurement

Quality Comparison

Item	Hokkaido Ezo Bafun Uni	Sanriku Iwate-kei Kitamurasaki Uni
Color	Vivid orange, golden orange; strong visual appeal	Pale yellow to light gold; more delicate
Taste	Rich, sweet, strong seaweed umami	Fresh, elegant, lighter sweetness
Texture	Thick, oily, long finish	Moist, clean palate, suitable for heavy usage
Brand Premium	High; Rishiri/Rausu/Hamanaka/Nemuro can be used for menu storytelling	Medium; Iwate Kita-Sanriku has origin story but lower premium
Stability	Premium products are stable but with significant price fluctuations	Good value in peak season, quality drops quickly in off-season
Loss Risk	High unit price; one box error results in substantial cost	Easier to control food cost

---

2. Dimension Comparison Table

Seasonal Comparison

Month	Hokkaido Ezo Bafun Uni	Sanriku Iwate-line Uni
Apr-May	Some Hokkaido production areas begin to have spring catch	Early supply begins, but not necessarily the fattest
Jun-Aug	One of the main peak seasons, with production areas like Rishiri, Rausu, Shakotan, and Nemuro rotating	Golden period, Iwate data indicates gonads enlarge from June to August, early summer to before Obon is the peak
Sep-Oct	Some sea areas still have, but quality begins to vary	Spawning approaches, quality becomes unstable
Nov-Mar	Some Hokkaido production areas, aquaculture/short-term storage, and Northern Territories supply support the premium market	Sanriku fresh product advantage weakens, more frozen/processed products

Logistics and Macau Procurement Costs

Cost Item	Hokkaido Ezo Bafun Uni	Sanriku Iwate Uni
Japan Domestic Consolidation	Hokkaido to Tokyo/Kansai requires an additional cold chain segment, with relatively higher time and cost	Tohoku to Tokyo is more convenient
International Air Freight	High-value products are suitable for small batch air freight, refrigerated at 0-5°C	Can also be air freighted, but when unit price is lower, fixed costs account for a higher proportion
Route to Macau	Direct shipment from Japan to Macau, or Japan to Hong Kong then cold chain transfer to Macau	Same as above
Documentation/Origin Risks	Hokkaido has better operability	Iwate is operable; Miyagi is not recommended
Loss/Damage	Premium raw uni has a short taste period, typically must be used within 1-2 days after arrival	Salt-packed is relatively easier to control, but still requires short turnover

Macau Japanese Cuisine Restaurant Procurement Recommendations

• High-end restaurant:
  Use Hokkaido Ezo-bafun uni as "limited origin" or "seasonal add-on price", clearly state the origin on the menu, e.g., "Hokkaido Hamana Ezo-bafun uni".

• Mid-high-end restaurant:
  Use Sanriku Iwate/Kita-Sanriki Kitamurasaki uni on weekdays, open Hokkaido red uni for weekends or VIP bookings.

• Cost control:
  If portion per serving is 30g:

• Hokkaido red uni Japan-side cost approx. ¥3,400-5,800 / portion
• Sanriku Iwate type approx. ¥1,200-2,400 / portion

• Excluding Macau landing cold chain, loss, labor, restaurant gross profit

• Pricing strategy:
  Hokkaido red uni should not be included in regular sets to absorb cost, should be standalone as "upgrade item". Sanriku Iwate type is suitable for lunch sets, gunkan, maki rolls, and donburi.

• 6 things to ask when querying suppliers:

• Variety: Ezo-bafun / Kitamurasaki
• Production prefecture: Hokkaido / Iwate / Miyagi
• Form: Packed / Brine / Jar / Frozen / Blanching
• Alum: With / Without
• Specifications: 100g, 150g, 250g, 300g
• Usable days after arriving in Macau: Ensure at least 1-2 days service window

Final Selection

Restaurant Scenario	Best Choice
High-end omakase	北海道エゾバフンウニ
Cost-controlled but still Japanese origin	三陸岩手キタムラサキウニ
Uni don focused on quantity	三陸岩手塩水ウニ
Menu story / Instagram worthiness	北海道利尻、羅臼、浜中、根室
Macau compliance stability	Prioritize Hokkaido, Iwate; avoid Miyagi source

Hokkaido Ezo Bafun Uni vs Sanriku Uni: Macau Japanese Cuisine B2B Procurement Comparison

---

3. Detailed Breakdown

Conclusion

For Macau Japanese restaurants pursuing high-end omakase / sushi counter with premium pricing: choose Hokkaido Ezobafun Uni, particularly from production areas like Hamanaka, Nemuro, Rishiri, and Rebun. These offer rich flavor, beautiful orange color, and strong storytelling appeal, making them ideal as a "Red Uni" selling point.

For stable gross profit, uni rice bowls, gunkan, lunch sets, and izakaya-style sashimi: choose Sanriku bottled uni / brine uni. Costs are approximately 35%–55% lower, with a cleaner, sweeter taste, and lower logistics and shrinkage pressures.

Strictly speaking, "Sanriku Bafun Uni" is not the mainstream term. The main Sanriku edible uni is approximately 90% Kita Murasaki Uni and about 10% Ezobafun Uni; most "Sanriku fresh uni / bottled uni" on the market are from the Kita Murasaki variety.

Toyosu "Uni" Overall Wholesale Price Reference	2026-04-28：セリ高値 ¥70,200/kg、中値 ¥11,256/kg、安値 ¥3,240/kg	Same category market price, not divided by origin	Premium box uni will be significantly higher than the average mid-price

Dimension Comparison Table

Dimension	Hokkaido Ezo Bafun Uni	Sanriku Raw Uni / Sanriku Bottle Uni	Macau Procurement Decision
Price	High. Public prices commonly around ¥65,000–¥116,000/kg, high-end boxes can be higher	Medium. Public bottle uni around ¥41,040/kg	Sanriku cost advantage obvious; Hokkaido suitable for high-margin single items
Specifications	Common 100g salt water pack, 250g/300g/400g box uni, arrange, loose, salt water	Common 150g milk bottle, salt water, no alum	Use Hokkaido "arrange" for nigiri/omakase; use Sanriku bottle uni for donburi/gunkan
Quality	Orange-rich, strong flavor, sweet, heavy oil feeling; Hamanaka farmed uni has GI, high market reputation	Yellow to pale yellow, more refined and refreshing taste, strong seawater character, good freshness in summer	High-end customers more easily perceive Hokkaido difference; Sanriku more stable for high-volume output
Service / Supply	Multiple Hokkaido production areas, high concentration in Toyosu; but weather, fishing bans, year-end demand push prices	Season concentrated, May–August strongest; bottle uni has "same-day shipping from catch" selling point	Sanriku peak season suitable for short-term menus; Hokkaido for year-round premium positioning
Location / Logistics	Hokkaido → Toyosu / Tokyo → Hong Kong / Macau, longer inland leg, high cold chain costs	Sanriku → Tokyo / Sendai → Hong Kong / Macau, more flexible direct delivery during peak season	Most Macau imports via Hong Kong cold chain, recommend 2–3 day turnover
Season	Hokkaido regions distributed: Nemuro Jan–Apr, Hidaka Mar–Jun, Rishiri Rebun May–Jun, Oshima Hiyama Jun–Aug, Okhotsk Apr–Aug	Sanriku natural raw uni main season mid-June to early August, bottle uni common May–Jul	Jun–Aug highest cost-performance for Sanriku; switch to Hokkaido/Northern Territories in winter/spring
Loss Risk	High-value goods, even small damage or melting affects margin; salt water no alum has better flavor but more fragile	Bottled/salt water easy to handle, but short shelf life, typically around 4 days	Macau restaurants should secure pre-orders first, not recommended to stock up
Menu Positioning	"Hokkaido Red Uni," "Hamanaka Ezo Bafun," "Nemuro Red Uni" can serve as premium wording	"Sanriku Bottle Uni" "Iwate Raw Uni" more approachable, seasonal	Use Hokkaido for high-end omakase; use Sanriku for seasonal promotions
Overall Score	4.6 / 5: High quality, brand, customer spending; cost pressure significant	4.2 / 5: Good cost-performance, seasonality, output volume; weaker premium scarcity	Macau B2B recommended dual-source procurement

Macau Sushi Restaurant Procurement Recommendations

• Omakase / 鮨店
• Recommended: Hokkaido Ezo bafun uni
• Usage: nigiri, hand roll, sashimi small plates
• Recommended specification: 100g brine pack testing; switch to 250g/300g box after stabilization

• Menu pricing: suitable for premium "red uni" à la carte, not suitable for all-you-can-eat or large bowl dishes

• Mid-to-High-End Japanese Cuisine / Izakaya

• Recommended: Sanriku bottle uni peak season + small amount of Hokkaido premium
• Usage: uni don, gunkan, cold tofu topping, uni soy sauce snacks

• Procurement strategy: leverage Sanriku seasonal benefit from Jun-Aug; switch to Hokkaido or imported bafun variety during off-season

• Cost Control Strategy

• Use Sanriku for volume: target food cost is easier to control
• Use Hokkaido for margin: limited nightly quantity, specify origin, specification, and arrival date
• Avoid "full Hokkaido inventory": when Macau turnover is not fast enough, waste will eat into gross margin

One-Sentence Conclusion

High-end Omakase/Business Banquets: Hokkaido Ezo Bafun Uni is Worth It.
Daily Sashimi, Uni Bowl, Family Customers, Tourist Sets: Sanriku Kita Murasaki Uni Offers Better Value.

In name, Sanriku can claim that "Bafun Uni" or "Ezo Bafun Uni" exists in small quantities, but public origin data shows that Sanriku raw uni is actually mainly Kita Murasaki Uni. Therefore, when Macau restaurants source, they should practically compare:

Sourcing Options	Actual Market Positioning
Hokkaido Ezo Bafun Uni	Rich, orange, high brand premium, commonly used by high-end sushi restaurants
Sanriku Kita Murasaki Uni	Yellow, fresh and elegant, short season, high cost-performance
Sanriku Ezo Bafun/Bafun	Exists, but small quantity, high difficulty for stable wholesale

Flavor Profile	Rich, sweet, kombu aroma, strong oiliness	Crisp, delicate, mineral notes, clean sea taste
Visual	Orange-red, strong sushi bar display appeal	Yellow to pale gold, more natural and rustic
Stability	Multiple origins and brands, but premium prices fluctuate significantly	Short season, supply easily disrupted by weather/sea conditions
Macau Ground Logistics Pressure	High-value goods can absorb air freight cold chain costs	Price advantage partially offset by small volume air freight dilution

B2B Wholesale Price Gap

Scenario	Hokkaido Ezo Baigai Uni	Sanriku Kitamurasaki Uni	Gap Assessment
Regular Premium Grade	¥35,000-60,000 / kg	¥40,000-50,000 / kg	Overlappable, Hokkaido not necessarily significantly more expensive
Branded Hokkaido Products: Hamanaka, Ogawa, Rishiri, Rausu	¥80,000-135,000 / kg	¥40,000-55,000 / kg	Hokkaido approximately 1.5-3 times
Top-tier Sushi Bar Designated Products	Can exceed ¥100,000 / kg	Less frequently enters the same tier auction narrative	Hokkaido clearly wins
Uni Don / Cooking Use	Relatively high cost	Easier to create volume appearance	Sanriku offers better value

Fresh Cold Chain Practical Additional Costs	Packaging, insulation, domestic transshipment, customs clearance, losses commonly add ¥2,500-5,000 / kg
100g Portion Allocation	Approximately ¥250-500 / 100g
Impact on Hokkaido Premium Products	Low proportion of goods value, easier to absorb
Impact on Sanriku Cost-Effective Products	Will weaken price advantage, but still suitable for donburi/set meals

Which One Is Worth It

• Based on profit margin, stable dish output, and family/tourist customer segment: Sanriku Kitamurasaki Uni offers better value.
• Based on average spend per customer, business entertainment, and Omakase appeal: Hokkaido Ezo-bafun Uni offers better value.
• Best procurement mix for Japanese cuisine in Macau: Use Sanriku as the core SKU, and Hokkaido for premium upselling.
• Do not feature "Sanriku Bafun Uni" as a long-term stable SKU; instead, rebrand it as "Sanriku Natural Raw Uni / Kitamurasaki Uni."
• Most cost-effective approach: Promote Sanriku seasonal limited edition from June to August; reserve Hokkaido Ezo-bafun Uni for business dinner service with limited daily availability.

常見問題 Frequently Asked Questions

Should Macau Japanese Restaurants Choose Hokkaido or Sanriku Sea Urchin?

Adopt a dual-line procurement strategy: use Hokkaido Ezobafun Uni (especially Rausu, Rishiri, Hamanaka, and Nemuro strains) for high-end and Omakase offerings, and Sanriku Iwate Kitamurasaki Uni for everyday gunkan and maki rolls.

What is the Price Difference Between Hokkaido and Sanriku Sea Urchin?

Hokkaido Ezobafun Uni costs approximately ¥33,800-58,000 per 250-300g, while Sanriku Iwate strains are around ¥19,800 per 250g—Hokkaido is approximately 1.7-3.3 times higher. After landing in Macau with cold chain costs included, the actual menu cost difference ranges from 40-120%.

Which Months Are Best for Procuring Hokkaido Sea Urchin?

June-August is the peak season, with production rotating through Rausu, Rishiri, Shakotan, and Nemuro regions. Quality is stable and prices are relatively reasonable during this period.

When Is Sanriku Sea Urchin at Its Fattest?

The golden period is June-August when the gonads are most enlarged, with the peak running from early summer until the Ghost Festival. Quality begins to differentiate from September-October, making the peak season the best value.

Can Macau Import Sea Urchin from Miyagi Nan Sanriku?

No, Macau still maintains bans on fresh food, animal-derived products, and aquatic products from Miyagi and 10 other prefectures. Procurement should focus on Iwate North Sanriku production areas.
