Japan Import Reselling Guide 2026: Mercari Japan to US Arbitrage Strategy
The Japanese secondhand market operates under entirely different dynamics than American resale platforms. Cultural factors—smaller living spaces, frequent relocations, and stigma against hoarding—create a robust secondhand ecosystem where premium goods sell for fractions of US prices. A vintage Levi’s jacket worth $80 in America might sell for ¥2,000 ($13-15) on Mercari Japan. Designer handbags commanding $400-600 stateside appear for ¥15,000 ($100-130) in Tokyo.
This price differential creates international arbitrage opportunities. Resellers importing from Japan to the US market exploit:
- Currency advantages (yen-dollar exchange rates favor USD buyers)
- Cultural valuation differences (Japanese market undervalues American vintage)
- Supply abundance (smaller homes = constant decluttering)
- Quality standards (Japanese sellers maintain items impeccably)
However, importing isn’t as simple as buying cheap and selling expensive. Proxy services, international shipping costs, customs duties, and product selection complexity create barriers most resellers never overcome. This comprehensive guide eliminates those barriers, teaching you exactly how to source profitable inventory from Mercari Japan and resell it for substantial margins in the US market.
Why Import from Japan? The Arbitrage Opportunity
Understanding why price differentials exist is essential to exploiting them:
Price Differentials: Japan vs. US Markets
The arbitrage stems from Asymmetric value perception:
American Vintage in Japan: Japanese fashion enthusiasts venerate American heritage brands (Levi’s, Champion, Patagonia) but the vintage secondhand market treats them as commodity clothing once initial retail excitement fades. A vintage 1980s Champion reverse weave sweatshirt—selling for $60-100 in US vintage shops—lists for ¥1,500-3,000 ($10-20) on Mercari Japan.
Why? Japanese consumers prefer:
- New, contemporary fashion
- Domestic Japanese brands (Comme des Garcons, Issey Miyake)
- Minimal clutter (Marie Kondo effect is real)
Result: American vintage floods Japanese secondhand markets at depressed prices.
Japanese Products in US: Conversely, authentic Japanese fashion brands, vintage kimonos, anime collectibles, and J-beauty products command premiums in the US from enthusiasts willing to pay for authentic access to Japanese culture.
Arbitrage Sweet Spots:
- Vintage American denim (Levi’s, Lee, Wrangler): 60-75% cheaper in Japan
- American workwear (Carhartt, Dickies vintage): 50-70% cheaper
- Outdoor brands (Patagonia, North Face vintage): 40-60% cheaper
- Vintage Nike/Adidas: 50-65% cheaper
- Japanese fashion brands (for resale in US): 30-50% cheaper than US boutiques
Unique Products Unavailable in America
Beyond pricing arbitrage, Japan offers products simply unavailable stateside:
Japanese Exclusive Collaborations:
- Nike Japan exclusives
- Uniqlo x Japanese artist collaborations (not released in US)
- Regional Pokémon merchandise
- Limited edition beauty products
Vintage Japanese Brands:
- 1990s-2000s Japanese streetwear (Bape, Undercover, Kapital)
- Designer pieces from Japanese designers (avant-garde fashion)
- Vintage Japanese denim brands (Evisu, Samurai, Momotaro)
Collectibles:
- Anime figures and limited editions
- Japanese Nintendo/gaming merchandise
- Vintage Japanese electronics (Walkmans, certain cameras)
These items cater to niche US collector markets willing to pay premiums for authenticity and rarity.
Quality & Authenticity Advantages
Japanese secondhand culture offers quality assurances rare elsewhere:
Cultural Quality Standards: Japanese society emphasizes meticulous care of possessions. “Used” items from Japan often appear barely worn—9/10 condition is standard, not exception.
Seller Honesty: Mercari Japan sellers obsessively disclose flaws. A listing noting “slight wear on corner” might describe damage barely visible to American eyes. This cultural overcaution about condition means you rarely receive items worse than described.
Counterfeit Rarity: While counterfeits exist everywhere, Japan’s consumer protection laws and cultural emphasis on authenticity mean significantly fewer fakes circulate on Japanese resale platforms versus Chinese or Southeast Asian markets.
Result: Buying from Japan provides quality floor higher than equivalent-priced US thrift store finds.
Market Examples: Nintendo, Vintage Fashion, Collectibles
Nintendo Products: Japan is Nintendo’s home market. Exclusive colors, limited editions, and regional releases appear on Mercari Japan months or years before US availability (if ever). Resellers import Japanese Switch consoles, special edition controllers, and region-free games at 20-40% below US eBay prices, then flip domestically.
Vintage Fashion Case Study: Vintage Levi’s 501s:
- Mercari Japan: ¥2,000-4,000 ($13-27)
- US eBay/Grailed: $60-95
- Potential margin: $35-70 per pair after all costs
At scale (importing 20+ pairs monthly), margins compound significantly.
Anime Figures: Limited edition figures released in Japan:
- Mercari Japan: ¥3,000-8,000 ($20-55)
- US eBay: $80-180
- Potential margin: $30-100 per figure
Niche but highly profitable for collectors with expertise authenticating figures and understanding which characters/series drive US demand.
Understanding Mercari Japan
Before importing, understand platform fundamentals:
What Is Mercari Japan? (Not the US App)
Critical Distinction: Mercari Japan and Mercari US are separate platforms:
Mercari Japan (mercari.com):
- Japanese-language interface
- Japanese yen (¥) pricing
- Japan-only shipping addresses accepted
- Requires proxy service for international buyers
Mercari US (mercari.com/us):
- English interface
- USD pricing
- US shipping addresses
- Completely separate inventory
You cannot buy from Mercari Japan using the US app or vice versa. They’re distinct marketplaces operated by the same parent company.
How Japanese Secondhand Culture Works
Japanese secondhand markets reflect unique cultural attitudes:
Space Constraints: Average Tokyo apartment is 700 sq ft (vs. 1,800 sq ft average US). Limited storage means constant decluttering. Selling used items isn’t stigmatized—it’s practical necessity.
Seasonal Turnover: Japanese fashion-conscious consumers turnover wardrobes seasonally. Last season’s Uniqlo? Sold on Mercari. This creates constant inventory flow.
Pricing Psychology: Japanese sellers prioritize quick sales over maximum profit. Items priced to move within days rather than weeks. “Better to sell for ¥1,000 today than store hoping for ¥2,000 eventually.”
Politeness Culture: Buying/selling involves ritualized politeness. Sellers package items immaculately (tissue paper, tape, handwritten thank-you notes). Even used items arrive looking gift-wrapped.
For resellers, this means abundant inventory, fair pricing, excellent condition items, and seller honesty about flaws.
Product Categories with US Resale Potential
Not everything on Mercari Japan makes sense to import:
High Potential Categories:
✅ Vintage American denim (largest arbitrage opportunity) ✅ Vintage streetwear (Nike, Champion, Patagonia) ✅ Japanese fashion brands (Bape, Kapital, Visvim for US resale) ✅ Vintage cameras/electronics (Nikon, Canon, Sony compacts) ✅ Anime collectibles (figures, limited edition goods) ✅ Designer bags/accessories (authentic Japanese market availability) ✅ Beauty products (Japanese/Korean beauty for US beauty enthusiasts)
Low Potential Categories:
❌ Heavy furniture (shipping costs destroy margins) ❌ Generic modern clothing (no US demand for fast fashion) ❌ Bulky items (anything over 2-3kg faces prohibitive shipping) ❌ Fragile ceramics (breakage risk too high) ❌ Licensed character goods with dubious IP (customs seizure risk)
Focus Rule: Import only items where US resale value is 3X+ total landed cost (product price + all fees/shipping).
Language Barrier Solutions
Mercari Japan is Japanese-language only. Solutions:
Google Translate:
- Translate entire page via Chrome browser
- Copy/paste item descriptions for translation
- Good enough for basic comprehension (not perfect but functional)
Proxy Service Interfaces:
- Buyee and other proxies offer English interfaces
- Search using English keywords (auto-translates to Japanese)
- Item descriptions auto-translated (quality varies)
Google Lens:
- Photograph Japanese text with phone
- Google Lens translates text in images
- Useful for deciphering sizing charts and condition notes
Key Japanese Terms to Learn:
- “美品” (bihin) = Excellent condition
- “未使用” (mishiyou) = Unused/new
- “サイズ” (saizu) = Size
- “送料” (souryou) = Shipping fee
- “傷” (kizu) = Scratch/damage
After 10-20 purchases, you’ll recognize common terms and navigate without constant translation.

Best Products to Import from Mercari Japan
Product selection makes or breaks import arbitrage:
Japanese Fashion & Streetwear (Bape, Undercover, Kapital)
Why These Work: Japanese streetwear brands command cult followings in US but limited retail distribution. Authentic pieces sell at premiums.
Top Brands to Import:
Bape (A Bathing Ape):
- Mercari Japan: ¥8,000-25,000 ($55-170) for hoodies/jackets
- US Grailed/eBay: $180-450

Authentication Critical: Learn to authenticate these brands (replica markets exist). Research logo placements, tags, stitching details before purchasing.
Vintage Denim & Americana (Levi’s, Selvedge Denim)
The Golden Arbitrage:
Vintage American denim is undervalued in Japan, overvalued in US—perfect arbitrage.
Levi’s 501s (1980s-1990s):
- Mercari Japan: ¥2,000-4,500 ($13-30)
- US eBay/Grailed: $55-95

Vintage Levi’s Trucker Jackets:
- Mercari Japan: ¥3,500-8,000 ($23-55)
- US Market: $80-160
- Profit: $35-80 per jacket
Lee, Wrangler, Vintage Carhartt:
- Similar arbitrage opportunities
- Slightly lower margins than Levi’s but more abundant inventory
Selvedge Denim (Japanese brands like Evisu, Samurai, Momotaro):
- Mercari Japan: ¥8,000-18,000 ($55-120)
- US Market: $180-400

Japanese Beauty & Skincare
J-Beauty Demand in US:
Japanese beauty products (sunscreens, sheet masks, skincare) have cult followings but limited US retail distribution.
Profitable Categories:
Sunscreens (Biore, Anessa):

- US Market: $25-55
- Margin: $10-25 per set
Limitations:
- Expiration dates (must check and disclose)
- FDA regulations (cosmetics okay; anything medicinal requires caution)
- Shipping restrictions (no aerosols, limited liquids)
Best Approach: Bundle multiples (5-10 items in one listing) to justify shipping costs and increase perceived value.
Vintage Cameras & Optics (Nikon, Canon, Olympus)
Film Camera Renaissance:
Film photography resurgence drives demand for Japanese vintage cameras.

Best Strategy: Specialize in specific models (research which cameras trending among film photography community). Canon AE-1, Olympus OM-1, Nikon FM2 consistently in demand.
Designer Goods (Cheaper Japanese Retail Market)
Japanese Luxury Market:
Authentic designer goods (Louis Vuitton, Chanel, Hermes) sell cheaper in Japan due to higher supply and constant turnover.
Arbitrage Potential:
Louis Vuitton Bags:
- Mercari Japan: ¥30,000-80,000 ($200-540) for classic models
- US Market: $450-1,200

- Mercari Japan: ¥15,000-35,000 ($100-235
- US Market: $280-600
- Profit: $100-280
Risks:
- Authentication crucial: Japan has counterfeits too
- Condition variance: Used luxury goods show wear
- Returns complex: International return shipping expensive
Only pursue if:
- You have authentication expertise
- You’re comfortable with higher-dollar inventory
- You can access authentication services (The RealReal, Fashionphile for verification)
Products to Avoid (Heavy, Fragile, Licensing Issues)
Don’t Import:
❌ Heavy Items (Boots, Thick Leather Jackets, Furniture):
- Shipping costs exceed profit margins

- Breakage rate too high
- Insurance costs erode margins
❌ Counterfeit-Prone Items Without Expertise:
- Supreme, Off-White, luxury goods if you can’t authenticate
- One counterfeit damages seller reputation permanently
❌ Licensed Character Goods with Dubious IP:
- Bootleg anime merchandise
- Customs can seize counterfeit IP goods
❌ Items with Complex Sizing (Shoes especially):
- Japanese shoe sizing different from US
- High return rates due to fit issues
Searching Mercari Japan Like a Pro
Efficiency separates profitable importers from money-losers:
Using Google Translate for Product Searches
Search Strategy:
English to Japanese Translation:
- Type “Levi’s 501” → Google Translate → “リーバイス501”
- Copy Japanese text into Mercari Japan search
Buyee Auto-Translate:
- Search English keywords through Buyee interface
- Auto-translates and searches Mercari Japan
- Less precise than manual Japanese search but easier
Brand Names Usually Don’t Need Translation:
- “Nike,” “Levi’s,” “Patagonia” work in English on Mercari Japan
- Japanese sellers use English brand names
Japanese Keyword Strategy & Brand Names
Effective Search Terms:
General Categories:
- “ビンテージ” (vintage)
- “レディース” (women’s)
- “メンズ” (men’s)
- “USA製” (made in USA)
- “古着” (used clothing/vintage)
Combine with Brand Names:
- “Levi’s ビンテージ” (Levi’s vintage)
- “Nike 古着” (Nike used/vintage)
Advanced Filters:
- Sort by “Price: Low to High” (find deals)
- Filter by condition (未使用 = unused)
- Filter by shipping (送料込み = shipping included)
Reading Product Descriptions (Condition, Flaws)
Japanese Condition Descriptors:
Excellent:
- “美品” (bihin) = Excellent condition, barely used
- “未使用品” (mishiyouhin) = Unused, like new
- “新品同様” (shinpin douyou) = Like new
Good:
- “目立った傷はありません” = No noticeable scratches
- “使用感あり” (shiyoukan ari) = Signs of use
- “多少の使用感” = Slight signs of use
Flaws:
- “傷あり” (kizu ari) = Has scratches/damage
- “汚れ” (yogore) = Stains/dirt
- “ほつれ” (hotsure) = Fraying/loose threads
- “色褪せ” (iroasase) = Fading
Key Listing Sections:
- Photos: Japanese sellers photographed flaws (zoomed-in shots of any damage)
- Condition: Listed in dropdown (新品 = new, 未使用に近い = nearly unused, 目立った傷や汚れなし = no noticeable damage, etc.)
- Description: Text describing item, often with measurements
Translation Tip: Chrome browser → Right-click → “Translate to English” translates entire page. Quality varies but sufficient for understanding condition notes.
Understanding Japanese Sizing (Clothing & Shoes)
Critical Difference: Japanese sizing runs 1-2 sizes smaller than American.
Clothing Size Conversion:
Tops/Jackets:
- Japanese S = US XS
- Japanese M = US S
- Japanese L = US M
- Japanese XL = US L
- Japanese XXL = US XL
Bottoms (Waist measurements more reliable than size labels):
- Always check waist measurement in cm
- Convert to inches (divide by 2.54)
- Example: 76cm waist = 30 inches
Shoes:
| Japanese (cm) | US Men | US Women |
|---|---|---|
| 24.5 | 6.5 | 8 |
| 25.0 | 7 | 8.5 |
| 25.5 | 7.5 | 9 |
| 26.0 | 8 | 9.5 |
| 26.5 | 8.5 | 10 |
| 27.0 | 9 | 10.5 |
| 27.5 | 9.5 | 11 |
| 28.0 | 10 | 11.5 |
| 28.5 | 10.5 | 12 |
Always Check Measurements: Reputable sellers list:
- Shoulder width (肩幅)
- Chest (身幅)
- Length (着丈)
- Sleeve (袖丈)
- Waist (ウエスト)
Convert cm to inches: Divide by 2.54
Pro Tip: Create measurement chart for your target US sizes. When you see listings, immediately compare measurements to your chart. Prevents sizing mistakes.
Spotting Authentic vs. Fake Products
Authentication Red Flags:
Price Too Good to Be True:
- Supreme hoodie for ¥3,000 ($20)? Definitely fake
- Bape jacket for ¥5,000 ($35)? Suspicious
Photos:
- Blurry photos hiding details
- Photos stolen from other listings (reverse image search)
- No close-ups of tags/logos
Seller Ratings:
- New sellers with zero feedback selling luxury goods
- Sellers with negative reviews mentioning authenticity
Listings:
- Generic descriptions, no specific details
- Multiple identical items (individual sellers shouldn’t have 10 identical Supreme hoodies)
Authentication Steps:
- Research Authentic Details: Study authentication guides for brands you import (fonts, tags, stitching)
- Request Additional Photos: Through Buyee, can request more photos before purchasing
- Check Seller History: View seller’s other listings and reviews
- Use Authentication Services Post-Purchase: For high-value items, pay for third-party authentication before relisting
Generally Safe Categories:
- Vintage Levi’s (rarely counterfeited due to low value)
- Nintendo products (buying from reputable sellers)
- Generic vintage clothing
High-Risk Categories:
- Supreme, Palace, Off-White
- Luxury designer (LV, Gucci, Chanel)
- Expensive streetwear (Bape, Undercover if suspiciously cheap)
Cost Analysis: Total Landed Cost Formula
Understanding true costs prevents unprofitable purchases:
Purchase Price on Mercari Japan
This is just the starting point, not final cost:
Example Item: Vintage Levi’s 501 jeans listed at ¥3,000 ($20 USD at ¥150/$1 exchange rate)
Proxy Service Fees (Buyee Example)
Service Fee: 500 yen base + 5% of item price
- ¥500 + (¥3,000 × 0.05) = ¥500 + ¥150 = ¥650 ($4.30)
Domestic Japan Shipping to Warehouse
Seller → Buyee Warehouse Fee: Typically ¥500 ($3.30)
(This varies by seller; Mercari Japan sellers often include shipping, but sometimes charge extra)
International Shipping Costs (EMS, DHL, Surface Mail)
This is the largest variable cost:
Weight-Based Pricing (Buyee International Shipping)::
EMS (Express Mail Service) - 7-10 days:
- 500g: ¥2,000 ($13)
- 1kg: ¥2,800 ($18.50)
- 2kg: ¥4,600 ($30)
Surface Mail - 2-3 months:
- 500g: ¥1,000 ($6.60)
- 1kg: ¥1,400 ($9.25)
- 2kg: ¥2,000 ($13)
DHL - 3-5 days (premium):
- 500g: ¥3,500 ($23)
- 1kg: ¥5,000 ($33)
- 2kg: ¥7,500 ($50)
Weight Estimation:
- T-shirts: 200-300g
- Jeans: 500-700g
- Hoodies/Jackets: 600-900g
- Shoes: 800-1,200g
Consolidation Advantage: Shipping 3 pairs of jeans together (1.8kg total) costs $30. Shipping individually (3 × ¥2,000 = $39) costs more. Always consolidate when possible.
Customs & Import Duties (De Minimis Rule)
US De Minimis Rule (2026): Packages valued under $800 declared value are duty-free.
What This Means:
- Single package with items totaling $750 declared value: No customs duties
- Package exceeding $800: Subject to duties (varies by product category, typically 5-15%)
Strategy:
- Keep package declared values under $800
- Ship multiple packages if ordering bulk
- Don’t lie on customs forms (illegal and risks seizure)
CBP Inspections:
- Customs and Border Protection randomly inspects packages
- Delays 3-7 days if inspected (normal)
- If counterfeit goods detected → seizure, no refund, possible penalties
PayPal/Credit Card Foreign Transaction Fees
PayPal: 4% fee on international transactions (Buyee accepts PayPal) Credit Card: 3-3.5% foreign transaction fee (unless using no-FTF card)
Fee Avoidance:
- Use credit cards with no foreign transaction fees (Capital One, Discover, some Chase cards)
- Factor PayPal fees into total cost calculations
Real Example: $30 Item → Total Cost Breakdown
Item: Vintage Levi’s 501 jeans on Mercari Japan
Cost Breakdown:
| Expense | Yen | USD |
|---|---|---|
| Item Price | ¥3,000 | $20.00 |
| Buyee Service Fee (500 + 5%) | ¥650 | $4.30 |
| Domestic Shipping (Seller → Warehouse) | ¥500 | $3.30 |
| International Shipping (EMS, 600g) | ¥2,000 | $13.30 |
| PayPal Fee (4% of ¥6,150) | ¥246 | $1.65 |
| TOTAL LANDED COST | ¥6,396 | $42.55 |
US Resale Price (Grailed/eBay): $75-85 eBay Fees (13%): ~$10 Shipping to Buyer (First Class): ~$5 Net Profit: $75 - $42.55 - $10 - $5 = $17.45
Margin: 41% ($17.45 profit / $42.55 cost)
Not amazing for single item, but repeat 30 times monthly = $523 profit. And many items have better margins.

Shipping from Japan: Methods & Costs
Shipping method selection balances speed, cost, and reliability:
EMS (Express Mail Service): Fast but Expensive
Speed: 7-10 days (Japan Post → USPS) Tracking: Full tracking both countries Insurance: Included up to ¥20,000 (~$135) Reliability: High (99%+ delivery rate)
When to Use:
- Time-sensitive items (reselling trending products)
- Valuable items needing tracking/insurance
- First orders (to receive inventory quickly and validate model)
Cost-Benefit: EMS costs 40-60% more than Surface Mail but delivers 75-90% faster. Worth it for most resellers prioritizing cash flow and customer satisfaction.
DHL/FedEx: Premium Speed, Higher Costs
Speed: 3-5 days Tracking: Real-time tracking Customs Clearance: Faster (DHL handles customs proactively)
When to Use:
- Ultra-valuable items ($500+) needing maximum security
- Replacing sold inventory urgently
- Business buyers willing to pay premium for speed
Cost-Benefit: Costs 50-80% more than EMS. Only justified for high-value items or urgent needs. Most resellers use EMS as speed/cost sweet spot.
Surface Mail: Cheap but 2-3 Months
Speed: 2-3 months (slow boat shipping) Tracking: Limited (basic tracking, not detailed) Insurance: Optional extra
When to Use:
- Restocking non-urgent inventory
- Heavy items where air shipping prohibitively expensive
- Building back-stock (order 3 months ahead of selling season)
Cost-Benefit: Saves 40-60% vs. EMS. Only viable if you have 2-3 month time horizon.
Risk: Packages occasionally lost (no recourse). Only use for lower-value items.
Package Consolidation Strategies
Consolidation = Combining Multiple Purchases into Single Shipment
Example:
- Buy 5 vintage tees over 2 weeks
- Each ships to Buyee warehouse
- Request consolidation into one box
- Ship combined package internationally
Benefits:
- Shipping Savings: One 2kg package costs ¥4,600 ($30). Five 400g packages cost 5 × ¥2,000 = ¥10,000 ($66). Savings: $36.
- Customs Simplicity: One package to clear vs. five
- Environmental: Less packaging waste
Buyee Consolidation Fees: ¥500-1,000 depending on number of items. Savings usually exceed consolidation fees.
Strategy:
- Order multiple items over 7-14 days
- Request consolidation once all arrive at warehouse
- Ship monthly consolidated packages to batch imports
Prohibited Items & Shipping Restrictions
Cannot Ship Internationally from Japan:
❌ Liquids over 100ml (beauty products, perfumes if large bottles) ❌ Aerosols (spray cans, compressed air) ❌ Batteries (lithium batteries have restrictions) ❌ Weapons (knives, replica swords) ❌ Counterfeit Goods (seizure risk at US customs)
Restricted Items (Possible but require special handling):
- Lighters (additional fees)
- Electronics with batteries (declare properly)
Always check: Buyee flags prohibited items during purchase. If unsure, message Buyee support before ordering.
Customs, Duties & Import Regulations
Understanding US import rules prevents surprises:
US Import Duty Thresholds ($800 De Minimis)
De Minimis Rule: Personal imports valued under $800 are duty-free and tax-free.
Critical Details:
- Per Shipment: Each package under $800 qualifies (can receive multiple $800 packages daily)
- Declared Value: Based on customs declaration (item value + intl shipping)
- Not Retail Value: Declared value is what you paid, not what item worth in US
Practical Application:
- Order ¥100,000 ($670) worth of items in single package: Duty-free
- Order ¥150,000 ($1,000) in single package: Subject to duties on full amount
Strategy: Structure orders to stay under $800 per shipment. If ordering bulk inventory, split into multiple shipments.
Declaring Package Value Correctly
Customs Form Requirements: Proxy services handle customs forms, but you verify:
Accurate Declared Value:
- Item purchase price
- International shipping cost
- Total = Declared Value
Example:
- Items: ¥90,000 ($600)
- Intl Shipping: ¥15,000 ($100)
- Declared Value: $700 (under $800, duty-free)
Undervaluation Risk: Declaring $200 package as “$50” to avoid duties:
- Illegal (customs fraud)
- Seizure risk if caught
- Insurance void (insurance based on declared value)
Never undervalue. Risks far exceed potential duty savings (which are often $0 under de minimis rule anyway).
CBP Inspections & Delays
US Customs and Border Protection randomly inspects imports:
Inspection Process:
- Package flagged for inspection
- CBP opens, examines contents
- Verifies compliance with regulations
- Releases or seizes
Typical Delays: 3-7 days if inspected (normal processing)
Inspection Triggers:
- Random selection (unavoidable)
- High value declarations
- Suspicious item descriptions
- Sender countries with counterfeit concerns
Minimal Concern If:
- Declared value accurate
- Items legal/non-counterfeit
- Proper documentation
What Happens If Item Seized:
- Receive seizure notice from CBP
- Explanation of violation
- No refund from seller/proxy (you assumed import risk)
- Possible penalties if counterfeit goods
Prevention: Only import legitimate goods, declare accurately, research prohibited items.
Restricted Items (Agricultural, Counterfeit Risks)
USDA Agricultural Restrictions:
- Wood products (certain woods prohibited)
- Seeds, plant materials
- Soil contamination (used shoes sometimes flagged)
Counterfeit Goods:
- CBP seizes counterfeit designer items
- “Replica” or “inspired by” items also subject to seizure
- Includes counterfeit electronics (fake Nintendo products)
Intellectual Property:
- Bootleg anime merchandise (unlicensed)
- Counterfeit trading cards
Best Practices:
- Research target items for import compliance
- Avoid obviously counterfeit goods
- When in doubt, don’t import
Reselling Imported Japanese Goods in the US
Successfully importing is half the equation; selling is the other:
Best Platforms for Japanese Imports (eBay, Grailed, Depop)
eBay (Best for Most Categories):
- Vintage denim/Americana: Huge buyer pool
- Electronics/cameras: Collector demand
- Anime figures: Dedicated collector community
Pros: Largest reach, reliable sales Cons: 13% fees
Grailed (Best for Fashion):
- Japanese streetwear (Bape, Undercover, Kapital)
- Vintage designer
- High-end denim
Pros: Fashion-focused audience, lower fees (9% + 3% payment) Cons: Smaller buyer pool than eBay
Depop (Best for Budget-Conscious Gen Z):
- Affordable vintage ($20-60 range)
- Streetwear
- 90s/Y2K fashion
Pros: Young engaged audience, social features Cons: Lower price points, gen Z price sensitivity
Mercari US (Fastest Turnover):
- Mid-range items ($ 30-100)
- Casual buyers
- Fast flips
Pros: Low fees (12.9%), simple interface Cons: Haggling culture, less serious collectors
Platform Strategy: List high-value items ($150+) on eBay and Grailed. List affordable items ($30-80) on Depop and Mercari US.
Pricing Strategy: US Market Research
Research BEFORE Importing:
Check Sold Listings:
- eBay: Filter “Sold Listings”
- Grailed: View sold data if available
- Depop: Check sold items (if public)
Price Points to Target:
- Vintage Levi’s: $55-95 (your landed cost ~$40-50)
- Japanese streetwear: $180-400 (your landed cost ~$80-200)
- Anime figures: $50-150 (your landed cost ~$25-70)
Pricing Formula: Landed Cost × 2.5-3.0 = List Price
Example:
- Landed cost: $45
- List price: $110-135
- After 13% eBay fees + shipping: Net $85-105
- Profit: $40-60
Testing: List first few items slightly above market average. If no movement in 10 days, reduce 10%. Find price point where items sell within 2 weeks.
Marketing Japanese Authenticity & Uniqueness
Listing Copy Angle:
Emphasize Japanese provenance:
Example - Vintage Levi’s: ❌ Generic: “Vintage Levi’s 501 jeans size 32”
✅ Optimized: “Rare Japan Market Levi’s 501 Selvedge Denim Vintage 1990s 32x32 Made in USA (Sourced from Japan)”
Why This Works:
- “Japan Market” signals quality
- “Sourced from Japan” creates authenticity narrative
- Japanese market Levi’s often better condition
Example - Japanese Streetwear: ✅“Bape Full Zip Hoodie (Japan Exclusive Colorway) Authentic Size L”
Narrative Marketing: “Sourced directly from Japan’s exceptional secondhand market where meticulous care ensures premium condition…”
Buyers pay premiums for authentic Japanese provenance. Make it central to your brand.
Handling Japanese Sizing Questions
Proactive Sizing Strategy:
Always Include:
- Measurements (chest, length, shoulders for tops; waist/inseam for bottoms)
- Size comparison (“Japanese XXL = US L-XL”)
- Disclaimer: “Sizes run smaller than US sizes; please verify measurements”
Example Listing Section:
SIZING NOTE: This is Japanese sizing which runs smaller than US sizes.
Tagged Size: L (Japan)
Equivalent US Size: Medium
Measurements (Flat Lay):
- Pit to Pit: 21"
- Length: 27"
- Shoulders: 18"
- Sleeves: 24"
Prevents Returns: Clear sizing info reduces “doesn’t fit” returns (your #1 return reason otherwise).
Competitive Advantage: Rare Inventory Sources
Differentiation Strategy:
Most US vintage resellers source from US thrift stores, competing for same inventory. You source from Japan—different inventory pool.
Marketing Angles:
- “Rare Japan-sourced vintage”
- “Authentic Japanese street fashion direct from Tokyo”
- “Curated from Japan’s premium secondhand market”
Niche Building: Specialize in specific category:
- “Japan-sourced vintage Americana specialist”
- “Authentic Japanese streetwear imports”
- “Rare Japfanese Nintendo collectibles”
Specialization builds reputation, repeat customers, and pricing power.
Avoiding Copyright & Trademark Issues
Risk Areas:
Bootleg Merchandise:
- Unlicensed anime goods
- Fake Nintendo products
- Counterfeit designer items
Trademark Violations:
- Using brand names improperly in titles
- Selling counterfeit as authentic
Platform Consequences:
- eBay/Grailed will remove listings
- Repeated violations → account suspension
- Counterfeit sales → permanent ban
Protection:
- Only source authentic licensed goods
- Disclose any “inspired by” or “style” items honestly
- Never claim counterfeit as authentic
- Research brands before importing
