Individual Agency Reviews
1. Rising Sun Commerce
A UK-based agency that built its expertise from the founders' own experience selling on Amazon Japan. It evolved into a service provider and now works with brands ranging from single-SKU operations to large global companies. Rakuten store setup is an available add-on, but Amazon remains the agency's core focus.
Strengths
- • Deep Amazon Japan operational knowledge
- • Mature processes for Western-market brands
- • English communication fluency
Limitations
- • Amazon-primary; Rakuten depth unverified
- • No Chinese-language support
- • UK-based team means significant time zone gap with Asia
Best for: Western brands comfortable with English-only communication, targeting Amazon Japan as a single entry point.
2. JPEX (Japan Experts)
Tokyo and Singapore-based, offering omnichannel coverage across Amazon, Rakuten, Shopify, and Yahoo! Shopping. Bilingual (English + Japanese) teams handle localization, PPC campaigns, logistics, and B2B market development. Offers a free 30-minute initial consultation; pricing is project-customized.
Strengths
- • Multi-platform (including Shopify Japan localization)
- • Japan-local team with regional perspective
- • Import fulfillment and B2B support available
Limitations
- • No Chinese-language support
- • Yakujiho compliance capability not explicitly disclosed
- • Broad service scope may mean shallower platform-specific depth
Best for: International brands (especially Southeast Asia or Singapore-based) needing multi-platform coverage with English as the primary communication language.
3. Humble Bunny
A Tokyo boutique agency founded in 2009 with over 83 brands launched in Japan, including Finnish outdoor children's brand Reima and Israeli skincare brand Dr. Fischer. Known for performance marketing and creative production, covering Amazon, Rakuten, Yahoo! Shopping, and ZOZOTOWN.
Strengths
- • 15+ years of Japan market experience
- • Strong creative production + paid advertising
- • Verified case studies with measurable outcomes
Limitations
- • No Chinese-language support

4. Next Level Global
An Amazon Service Provider Network (SPN)-certified agency providing bilingual (English + Japanese) digital marketing and marketplace management. Notably offers ACP (Attorney for Customs Procedures) services — a differentiated capability for brands that need import compliance support alongside marketplace management.
Strengths
- • Amazon SPN official certification
- • ACP customs compliance services
- • B2B sales development support
Limitations
- • No Chinese-language support
- • Rakuten operational depth below Amazon focus

5. Japan EC (N-Marketing)
A Nagoya-based agency with a bilingual Japanese + Chinese team, primarily serving Chinese and Taiwanese brands entering Rakuten, Amazon, and Yahoo! Japan. Operates its own warehouse in Nagoya for centralized fulfillment, offering same-day order dispatch and returns handling.
Strengths
- • Native Chinese communication
- • Own warehouse with fast fulfillment
- • Covers Rakuten, Amazon, and Yahoo!
Limitations
- • English capability unclear — limits global brand fit
- • Yakujiho compliance not explicitly addressed
- • Smaller scale may limit capacity for complex accounts
Best for: Small-to-mid Chinese or Taiwanese brands prioritizing Chinese communication and local warehouse logistics.
Why Asian Brands Face Unique Challenges in Japan
Most of the agencies above perform well for Western clients, but brands originating from China, Taiwan, or Southeast Asia face a distinct set of challenges that most agencies are not fully equipped to handle:
Three-Language Coordination Gap
Brands operate internally in Chinese, Japan requires Japanese-native content, and global stakeholders communicate in English. Agencies supporting only two languages create translation gaps or coordination friction at one layer.
Yakujiho Is a Hard Compliance Gate
Beauty, skincare, and health product claims are strictly regulated under Japan's Pharmaceutical and Medical Device Act (Yakujiho). Violations result in immediate listing removal — not fines. Many general-purpose agencies lack systematic review processes for this.
Platform Cold-Start Complexity
Rakuten and Amazon Japan have fundamentally different advertising logic, review systems, and promotional calendars. Brands scaling quickly need operational depth on both — not just the ability to "open a store."
End-to-End Coordination Need
Chinese brands often need to handle customs, labeling, warehousing, and marketplace operations simultaneously. Single-platform specialists cannot coordinate across the full supply chain.
5 Questions to Ask Any Japan EC Agency Before Signing
-
Q1: Do you have case studies in my product category — specifically on both Rakuten and Amazon Japan — with actual performance data?
⚠ Agencies that deflect to general "experience" claims without concrete numbers are a signal.
-
Q2: Who handles Yakujiho compliance review? Is there an internal process or an external legal consultant?
⚠ If the answer is "the brand handles it," you carry the risk.
-
Q3: What does a monthly report include? Can I see a sample?
⚠ Summary sales reports without traffic source, ad efficiency, or ranking data mean limited visibility.
-
Q4: If I want to expand or reduce service scope in 6 months, how does the contract handle that?
⚠ Rigid contracts with high exit fees transfer risk entirely to you.
-
Q5: Are the people managing Rakuten and Amazon the same team or different specialists?
⚠ One person covering both platforms usually means insufficient depth on at least one.
