1. Comparison Overview

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

First, Let's Discuss the Procurement Conclusions

Macanese Japanese restaurants should adopt "dual-line procurement":

Use	Recommendation
Omakase / premium sashimi / signature uni rice bowl	Hokkaido ezobafun uni, particularly those from Rausu, Rishiri, Hamanaka, and Nemuro
Daily gunkan, rolls, set meals, and cost control	Sanriku Iwate-type kitamurasaki uni / salted uni
Not recommended	Products from Minami-Sanriku in Miyagi Prefecture, as Macau still maintains a ban on fresh food, animal-derived products, aquatic products, and aquatic product preparations from 10 prefectures including Miyagi

Core Price Differential

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

Comparison Item	Hokkaido Ezo-bafun Uni	Sanriku Iwate-system Uni	Price Difference Assessment
Premium boxed / folded open 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 / Mid ¥35,000 / Low ¥9,500, unit "one piece"	Same market classification, mixed origin	Premium red uni pushes up the ceiling
Estimated after landing in Macau	Add cold chain, loss, customs clearance, agent margin per 100g	Same cost addition, but low-price goods more affected by fixed costs	Actual menu cost difference usually still 40-120%

Distinguish Between Variety and Name

Name	Actual Situation	Restaurant Procurement Implications
Hokkaido Ezobafun Uni	True "red uni", orange in colour, strong flavour, intense sweetness, high umami density	Suitable as a premium centrepiece dish
Sanriku Bafun Uni	Often broadly referred to in the market as "Sanriku uni", but approximately 90% of the edible catch in Iwate is actually Kita Murasaki Uni, with only about 10% being Ezobafun Uni	When procuring, clarify whether it is "Kita Murasaki" or "Ezobafun"
Miyagi Minami Sanriku Uni	Available public data mainly points to Kita Murasaki Uni	There is regional import risk for Macau; Miyagi-sourced products should not be part of regular procurement

Quality Comparison

Item	Hokkaido Ezobafun Uni	Sanriku Iwate-style Kitamurasaki Uni
Colour	Bright orange, golden orange, strong visual appeal	Pale yellow to light gold, more delicate
Flavour	Rich, sweet, strong seaweed umami	Refined, elegant, lighter sweetness
Texture	Thick, oily mouthfeel, long finish	Moist, palate-cleansing, suitable for bulk use
Brand Premium	High, Rishiri/Rausu/Hamanaka/Nemuro can be used for menu story	Medium, Iwate Kita-Sanriku has origin story but lower premium
Stability	High-end product is stable, but price fluctuates greatly	Good value in peak season, quality drops quickly in off-season
Wastage Risk	High unit price, one box error costs significantly	Easier to control food cost

---

2. Dimension Comparison Table

Seasonal Comparison

Month	Hokkaido Ezo-bafun Uni	Sanriku Iwate-type Uni
April-May	Some Hokkaido production areas begin to have spring catch	Early supply begins, but not necessarily the fattest
June-August	One of the main peak seasons, with production areas such as Rishiri, Rausu, Shakotan, and Nemuro rotating	Golden period – Iwate data indicates gonad enlargement from June to August, with early summer to before the Obon festival being the peak
September-October	Some sea areas still have it, but quality begins to vary	Spawning approaches, quality is unstable
November-March	Some Hokkaido production areas, aquaculture/short-term holding, and Northern Territories supply support the premium market	Sanriku fresh product advantage weakens, with more frozen/processed products

Logistics and Macau Procurement Costs

Cost Item	Hokkaido Ezo-bafun Uni	Sanriku Iwate-type Uni
Domestic Japan Collection	Hokkaido to Tokyo/Kansai requires an additional cold chain segment, with higher time and cost	Tohoku to Tokyo is more straightforward
International Air Freight	High-value goods 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 from Japan to Macau, or Japan to Hong Kong then cold chain to Macau	Same as above
Documentation/Origin Risk	Hokkaido has better operability	Iwate is operable; Miyagi is not recommended
Loss/Damage	Premium raw uni has a short shelf life, typically must be used within 1-2 days of arrival	Salt water packs are relatively easier to control, but still require short turnover

Macau Japanese Restaurant Procurement Recommendations

• High-end establishment:
  Use Hokkaido Ezo bafun uni for "limited origin" or "seasonal supplemental pricing", clearly state the origin on the menu, e.g. "Hokkaido Hamanaka Ezo bafun uni".

• Mid-to-high-end establishment:
  On weekdays, use Sanriku Iwate/Kita Sanriku Kitamurasaki uni; on weekends or for VIP bookings, open Hokkaido red uni.

• Cost control:
  If using 30g of uni per portion:

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

• Excludes Macau landing cold chain, wastage, labour, and restaurant margin

• Pricing strategy:
  Hokkaido red uni should not be included in regular set menus to absorb costs; it should be a standalone "upgrade item". Sanriku Iwate variety is suitable for lunch sets, gunkan maki, rolls, and donburi.

• Six things to ask suppliers when requesting quotes:

• Variety: Ezo bafun / Kitamurasaki
• Origin prefecture: Hokkaido / Iwate / Miyagi
• Form: block / brine / jar / frozen / blanched
• Alum: with / without
• Specification: 100g, 150g, 250g, 300g
• Days usable after arrival in Macau: must 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-conscious but still want Japanese origin	三陸岩手キタムラサキウニ
Uni donburi focusing on quantity	三陸岩手塩水ウニ
Menu story / Instagram value	北海道利尻、羅臼、浜中、根室
Macau compliance and stability	Prioritise Hokkaido, Iwate; avoid Miyagi source

3. Detailed Breakdown

Conclusion

For Macau Japanese restaurants doing high-spend omakase / sushi counter: Choose Hokkaido Ezo Bafun Uni, especially from producing areas like Hamanaka, Nemuro, Rishiri, and Rebun. These have intense flavour, beautiful orange colour, and strong storytelling appeal, making them suitable as a "red uni" selling point.

Menu Positioning	"Hokkaido Red Uni," "Hamanaka Ezo-bafun," "Nemuro Red Uni" can be used as premium wording	"Sanriku Bottle Uni," "Iwate Raw Uni" more approachable, has seasonal feel	High-end omakase uses Hokkaido; seasonal promotion uses Sanriku
Overall Score	4.6 / 5: Quality, brand, high customer spend; cost pressure big	4.2 / 5: Value for money, seasonal feel, good output; premium scarcity weaker	Macau B2B recommends dual-line procurement

Macau Japanese Restaurant Procurement Recommendations

• Omakase / Sushi Restaurant
• Recommended: Hokkaido Ezo Bafun Uni
• Usage: Nigiri, temaki, small sashimi plates
• Recommended specification: Test with 100g salt water pack; switch to 250g / 300g box after stable

• Menu price: Can be offered as premium "red uni" à la carte, not suitable for unlimited or large bowl dishes

• Mid-to-High-End Japanese / Izakaya

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

Procurement strategy: Capitalise on Sanriku seasonal bonus from June–August; switch to Hokkaido or imported Bafun varieties in off-season

• Cost Control Strategy

• Use Sanriku for volume: Food cost target easier to achieve
• Use Hokkaido for margin: Limited nightly quantity, specify origin, specification, and arrival date
• Avoid "full Hokkaido always in stock": When Macau turnover isn't fast enough, wastage will eat into gross margin

Hokkaido Ezobafun Uni vs Sanriku Uni: B2B Procurement Decision for Macau Japanese Cuisine

One-sentence Conclusion

High-end Omakase/Business Entertaining: Hokkaido Ezo Bafun Uni is worth it.
Daily Sashimi, Uni Donburi, Family Customers, Tourist Sets: Sanriku Kitamurashiki Uni offers better value.

In theory, Sanriku can claim that "Bafun Uni" or "Ezo Bafun Uni" exists in small quantities, but public production data shows that Sanriku raw uni is actually mainly Kitamurashiki Uni. Therefore, when Macau restaurants procure, in practice they should compare:

Procurement Option	Actual Market Positioning
Hokkaido Ezo Bafun Uni	Rich, orange, high brand premium, commonly used by high-end sushi restaurants
Sanriku Kitamurashiki Uni	Yellow, refreshing and elegant, short season, high cost-performance
Sanriku Ezo Bafun/Bafun	Exists, but in small quantities; stable wholesale is difficult

Important Numbers

Metric	Hokkaido Ezobafun Uni	Sanriku Kitamurasaki Uni
Japan Public Retail / Quasi-Wholesale Observation Price	Approx. ¥8,800-14,800 / 250g common; premium brands up to ¥33,800-38,800 / 250-300g	Approx. ¥3,870 / 80g
Per kg Conversion	Approx. ¥35,200-59,200 / kg; premium brands approx. ¥129,000-135,000 / kg	Approx. ¥48,375 / kg
Typical B2B Procurement Gap	Hokkaido premium typically 30%-150% more expensive	20%-60% cheaper than Hokkaido brand-name Ezobafun
Season	Hokkaido rotates by sea area, Rausu Jan-Jun, Rebun from Jun, etc.	Sanriku natural raw uni peak mid-Jun to early Aug
Flavour Profile	Rich, sweet, konbu aroma, strong oiliness	Light, 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 volatile	Short season, supply easily disrupted by weather/sea conditions
Macau Landing Logistics Pressure	Premium 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-bafun Uni	Sanriku Kitamurasaki Uni	Gap Assessment
Regular premium grade	¥35,000-60,000 / kg	¥40,000-50,000 / kg	Can overlap; Hokkaido not necessarily always considerably more expensive
Branded Hokkaido products: Hamanaka, Ogawa, Rishiri, Rausu	¥80,000-135,000 / kg	¥40,000-55,000 / kg	Hokkaido is approximately 1.5-3 times higher
Top-tier sushi bar designated products	Can exceed ¥100,000 / kg	Less frequently enters the same tier of auction narrative	Hokkaido clearly dominates
Uni-don / culinary use	Higher cost	Easier to create volume	Sanriku offers better value

Impact of Logistics Costs on Macau Restaurants

Cost Item	Estimated Impact
Public Air Freight Reference from Japan to Macau Airport	Approx. ¥778 / kg base air freight and fuel surcharge
Fresh Cold Chain Practical Additional Costs	Packaging, insulation, domestic transit, customs clearance, losses commonly add ¥2,500-5,000 / kg
100g Portion Allocation	Approx. ¥250-500 / 100g
Impact on Hokkaido Premium Goods	Low proportion of goods value, easier to absorb
Impact on Sanriku Value-for-Money Goods	Will weaken price advantage, but still suitable for donburi/set meals

Macau Japanese Restaurant Procurement Recommendations

Restaurant Positioning	Recommended	Reason
High-end Omakase	Hokkaido Ezo Bafun Uni	Customers are willing to pay for origin, colour, richness, and brand story
Mid-to-high-end sushi restaurant	Hokkaido + Sanriku dual track	Use Hokkaido for nigiri, Sanriku for donburi/side dishes; more stable margins
Izakaya/family Japanese cuisine	Sanriku Kitamurasaki Uni	Clean taste, lower cost, portions can be generous
Hotel Japanese cuisine	Hokkaido for premium upsell, Sanriku for buffet/set menu	Can clearly segment pricing
Tourist area restaurant	Sanriku as main, Hokkaido for paid upgrade	Travellers value "direct from Japan" more than detailed regional distinctions
Business entertainment	Hokkaido Ezo Bafun Uni	Visuals and narrative are more impressive

Application Scenario Recommendations

Scenario	Best Suited	Menu Description
Family	Sanriku Kitamurasaki Uni	"Sanriku Natural Fresh Uni Donburi"
Couples	Hokkaido Ezobafun Uni (small portion) mixed with Sanriku	"Hokkaido Red Uni · Sanriku White Uni Tasting Comparison"
Business	Hokkaido Ezobafun Uni	"Hokkaido Hamakuchi/Raika Ezobafun Uni"
Travellers	Sanriku Main + Hokkaido Upgrade	"Freshly Arrived from Japan Uni Donburi; Hokkaido Red Uni Upgrade Available"
Omakase	Hokkaido	"Today's Hokkaido Red Uni"
Uni Donburi	Sanriku	Controllable cost, strong portion presence
Sashimi Platter	Hokkaido (small garnish)	Colour and richness as the main feature
Heated Dishes	Sanriku or Frozen Premium Uni	Top-grade Hokkaido uni should not be wasted on high-heat dishes

Which One Is Worth It

• Regarding gross profit, stable supply, and family/tourist customers: Sanriku Kitamurasaki Uni is more worth it.
• Regarding average spend, business entertaining, and omakase persuasiveness: Hokkaido Ezobafun Uni is more worth it.
• Best procurement combination for Macau Japanese cuisine: Sanriku as the main SKU, Hokkaido for premium upsell.
• Don't feature "Sanriku Bafun Uni" as a long-term stable SKU; should rewrite as "Sanriku Natural Raw Uni / Kitamurasaki Uni".
• Most cost-effective approach: promote Sanriku seasonal limited edition from June to August; keep Hokkaido Ezobafun Uni with small daily quantity for business dinner service.

Common Questions Frequently Asked Questions

Should Macau Japanese restaurants choose Hokkaido or Sanriku sea urchin?

Use a dual-line procurement strategy: use Hokkaido Ezo bafun uni (especially Rausu, Rishiri, Hamanaka, and Nemuro varieties) for high-end and Omakase items, and use Sanriku Iwate Kita-murasaki uni for everyday gunkan-maki and rolls.

How many times more expensive is Hokkaido compared to Sanriku sea urchin?

Hokkaido Ezo bafun uni is approximately ¥33,800-58,000/250-300g, while the Sanriku Iwate variety is approximately ¥19,800/250g — Hokkaido is about 1.7-3.3 times higher. After landing in Macau with cold chain costs, the actual menu cost difference is 40-120%.

Which months are best for procuring Hokkaido sea urchin?

June-August is the main peak season, with production areas like Rishiri, Rausu, Shakotan, and Nemuro rotating, offering stable quality and relatively reasonable prices.

Which months is Sanriku sea urchin at its fattest?

June-August is the golden period, with肥大 reproductive glands; early summer until the Ghost Festival is the peak period. From September-October, quality begins to differentiate, making the peak season the best value for money.

Can Macau import sea urchin from Miyagi Prefecture's Southern Sanriku?

No, Macau still maintains a ban on imports of fresh food, animal-derived products, and aquatic products from 10 prefectures including Miyagi. Procurement should be from the Iwate Northern Sanriku production area.
