Haruna Kojima Shopify Plus Cross-Border Growth: A Replicable APAC Playbook

Quick Answer: Haruna Kojima's Her lip to brand achieved 400% cross-border revenue growth and 149% repeat customer increase by migrating to Shopify Plus, using Shopify Markets for multi-currency management, phased market expansion, localized content, and automated post-purchase flows — a strategy replicable by any APAC DTC brand.

When Heart Relation Inc. decided to take Haruna Kojima's fashion brand "Her lip to" from a Japan-only direct-to-consumer label to a cross-border commerce operation, the results were hard to ignore: a 149% increase in repeat customers and a 400% surge in cross-border ecommerce revenue after migrating to Shopify Plus (Shopify Case Study, 2024). Those numbers got our attention at Branch8 — not because they're impressive on a slide deck, but because they reflect a pattern we've seen repeatedly when APAC brands get their cross-border infrastructure right.

The Haruna Kojima Shopify Plus Cross-Border Growth Strategy Deconstructed

Her lip to launched in 2018 as a Japan-domestic brand. By 2023, it had outgrown its original ecommerce stack. The core problems were familiar to anyone who's operated cross-border from Asia:

• Currency and payment fragmentation — Japanese consumers expect konbini payments and PayPay; international buyers need Apple Pay, credit cards, and local wallets
• Shipping cost transparency — Duties and delivery fees presented at checkout kill conversion when selling from Japan to the US, EU, or Southeast Asia
• Localization beyond translation — Size charts, product descriptions, and return policies need to feel native to each market

Heart Relation solved these by consolidating onto Shopify Plus with its expansion store architecture. Rather than running separate instances for each country, they used Shopify Markets to manage pricing, languages, and duties from a single admin panel. According to Shopify's published case study, the migration delivered that 400% cross-border revenue increase within the first year (Shopify, 2024).

The takeaway isn't "use Shopify Plus." The takeaway is that consolidating your multi-market operations into a single platform with native international commerce capabilities eliminates the operational drag that kills cross-border margins.

Why Japan-to-World Is the Hardest Cross-Border Path in APAC

Japan's domestic ecommerce market generated approximately ¥22.7 trillion (USD $154 billion) in 2023, according to Japan's Ministry of Economy, Trade and Industry (METI, 2024). That scale creates a comfort trap: brands can grow to significant revenue without ever selling internationally.

But Japan-to-world cross-border is technically harder than, say, Singapore-to-world or Hong Kong-to-world for specific reasons:

Language and character encoding complexity

Japanese product catalogs use a mix of kanji, hiragana, katakana, and romaji. Automated translation tools like DeepL or Google Translate produce passable English but mangled Korean or Traditional Chinese. Her lip to invested in human-edited translations for their top 20% of SKUs by revenue, and machine translation with manual QA for the rest. This tiered approach is exactly what we recommend to clients.

Shipping economics from Japan

Japan Post suspended many international services during COVID and only partially restored them. DHL and FedEx rates from Japan are 30-50% higher than from Hong Kong or Singapore for equivalent parcel weights, according to Parcel Monitor's 2024 rate comparison data. Her lip to addressed this by using Shopify Plus's calculated shipping rates with third-party logistics (3PL) partners who consolidate parcels.

Regulatory overhead

Japan's Act on Specified Commercial Transactions requires specific disclosures that differ from standard Shopify checkout flows. Customizing the checkout — which Shopify Plus allows through checkout extensibility — was a prerequisite, not an optimization.

The 149% Repeat Customer Metric: What Actually Drove It

Repeat purchase rate is the metric that separates sustainable DTC brands from one-hit wonders. Her lip to's 149% increase in repeat customers didn't come from discounting. Based on the publicly available details and patterns we've implemented for similar brands, here's what moved the needle:

Shopify Flow automations for post-purchase engagement

Shopify Plus includes Shopify Flow, which allows no-code automation workflows. A typical repeat-purchase sequence looks like this:

1Trigger: Order fulfilled
2Condition: Customer tag = "first_purchase" AND order.shipping_address.country != "JP"
3Action:
4  → Wait 7 days
5  → Send email via Klaviyo (template: cross-border-welcome-series)
6  → Add customer tag: "intl_nurture_active"
7  → Wait 21 days
8  → Send email via Klaviyo (template: size-guide-followup)

This kind of segmented post-purchase flow — different for domestic vs. international customers — is trivially easy on Shopify Plus but requires custom development on most other platforms.

Loyalty mechanics built on Shopify's customer metafields

Rather than bolting on a heavy loyalty app, Her lip to used Shopify's native customer metafields to track engagement tiers. This reduces app bloat (a real performance concern — every third-party script adds 200-500ms to page load, per WebPageTest benchmarks) while keeping the loyalty data inside the platform.

Localized returns experience

According to Narvar's 2024 State of Returns report, 67% of cross-border shoppers check the return policy before purchasing. Her lip to used Shopify Plus's multi-language capabilities to present market-specific return policies — a detail that most brands overlook but that directly impacts repeat purchase intent.

How Does This Compare to Other APAC Cross-Border Migrations?

We migrated Chow Sang Sang — one of Hong Kong's largest jewelry retailers — from a legacy on-premise system to a headless Shopify Plus architecture serving Hong Kong, Macau, and Mainland China markets in 14 weeks. The technical parallels to Her lip to's migration are instructive:

Similar challenges

• Multi-currency pricing with market-specific margins (gold pricing in HKD vs. RMB requires daily recalculation)
• Checkout customization for local payment methods (Alipay HK, WeChat Pay, FPS)
• Product information management across languages (Traditional Chinese, Simplified Chinese, English)

Different scale, same architecture

Chow Sang Sang manages thousands of SKUs with daily price updates tied to commodity markets. Her lip to runs seasonal drops with limited inventory. But both benefit from Shopify Plus's same core capability: a single admin managing multiple storefronts with market-specific configurations.

The configuration that enables this in Shopify Plus's markets.json:

1{
2  "markets": [
3    {
4      "name": "Japan (Primary)",
5      "currency": "JPY",
6      "languages": ["ja"],
7      "duties_included": true,
8      "domain": "herlipto.jp"
9    },
10    {
11      "name": "Global",
12      "currency": "USD",
13      "languages": ["en"],
14      "duties_included": false,
15      "domain": "herlipto.com/en"
16    }
17  ]
18}

This market segmentation approach, combined with Shopify Functions for market-specific discount logic, gives brands the flexibility of separate stores with the operational efficiency of a unified backend.

Building Your Own Cross-Border Growth Plan on Shopify Plus

Her lip to's playbook is replicable, but the sequence matters. Based on our experience deploying Shopify Plus cross-border stores across Hong Kong, Singapore, Taiwan, and Australia, here's the implementation order that minimizes risk:

Phase 1: Domestic consolidation (Weeks 1-4)

Migrate your primary market to Shopify Plus first. Get your product data clean, your checkout optimized, and your post-purchase flows automated before adding international complexity. According to Shopify's own migration documentation, brands that stabilize domestically first see 35% fewer support tickets during international rollout.

Phase 2: First expansion market (Weeks 5-8)

Choose your highest-intent international market based on existing traffic data (check Google Analytics 4's geographic reports). For Japanese brands, this is almost always the US, followed by Taiwan and Hong Kong. For Hong Kong brands, it's typically Singapore or Australia.

Configure Shopify Markets for this single additional market:

• Set local currency and pricing rules
• Enable duty and tax estimation via Shopify's built-in calculator or a partner like Zonos
• Deploy translated product content for your top 50 SKUs by pageview

Phase 3: Multi-market scaling (Weeks 9-16)

Add remaining markets incrementally. Each new market should take 1-2 weeks if your foundation is solid. The diminishing effort per market is where Shopify Plus's cross-border growth platform justifies its $2,300/month price tag (Shopify Plus pricing, 2024).

The Marketing Layer That Amplifies Cross-Border Revenue

Her lip to's Haruna Kojima Shopify Plus cross-border growth marketing approach leveraged something most APAC brands underutilize: the founder's personal brand as a trust signal in new markets.

Haruna Kojima's 5+ million social media followers across Instagram and X (formerly Twitter) provided built-in international awareness. But the technical execution mattered more than the follower count:

• UTM-tagged social links routed to market-specific landing pages (not a generic homepage)
• Shopify Plus's Script Editor (now migrated to Shopify Functions) applied market-specific welcome offers automatically
• Klaviyo integration captured email subscribers by market, enabling localized email flows from day one

According to Klaviyo's 2024 Ecommerce Benchmark Report, brands using segmented international email flows see 2.4x higher revenue per email compared to one-size-fits-all campaigns. Her lip to's repeat customer growth strongly suggests they're executing on this.

For brands without a celebrity founder, the same mechanics work with micro-influencer partnerships in each target market. We've seen Taiwan-based lifestyle brands achieve comparable repeat purchase rates by partnering with 3-5 local KOLs per market, each driving traffic to localized Shopify Plus storefronts.

What APAC Brands Get Wrong About Cross-Border Expansion

After implementing cross-border Shopify Plus stores for brands across six APAC markets, the failure patterns are predictable:

Launching too many markets simultaneously

Every market you add is a support burden. Returns, customer inquiries, payment disputes — they all multiply. Her lip to was disciplined about phasing. We tell clients: unless you have dedicated support staff for a market, don't launch there.

Ignoring landed cost transparency

A study by the Baymard Institute (2024) found that unexpected costs at checkout are the #1 reason for cart abandonment at 48%. Cross-border shoppers are especially sensitive. Shopify Plus's duty and import tax estimation — powered by its partnership with Global-e — addresses this, but only if you enable it.

Treating translation as localization

Translating your site into English doesn't make it an international store. Localization means adapting sizing (Japan uses its own sizing system), adjusting imagery for cultural context, and rewriting — not translating — product descriptions. Her lip to's investment in editorial-quality English content for their global store is a competitive advantage that most Japanese brands skip.

What to Do Monday Morning

If you're running a DTC brand in the Asia-Pacific and want to replicate Her lip to's cross-border growth trajectory, here are three immediate actions:

1. Audit your international traffic today. Open GA4, navigate to Reports → User → Demographic Details → Country. If more than 10% of your traffic comes from outside your primary market and you're not selling there, you're leaving money on the table. Export this data — you'll need it for Phase 2 planning.
2. Request a Shopify Plus demo with the Shopify Markets walkthrough. Specifically ask about duty/tax estimation accuracy for your product categories and target markets. Not all HS codes are equally well-supported, and you need to know before committing.
3. Map your top 20 SKUs for localization. These are the products that will form your international beachhead. Get quotes for human translation into your target market's language. Budget $0.08-0.15 per word for professional ecommerce translation in APAC languages (ProZ.com rate index, 2024).

The path from domestic DTC brand to cross-border success isn't about grand strategy — it's about getting the infrastructure right, then executing market by market. Her lip to proved the model works. The question is whether you'll build yours before your competitors do.

If your team needs help architecting a Shopify Plus cross-border deployment for APAC markets, reach out to Branch8. We've done this across Hong Kong, Singapore, Taiwan, Australia, and Southeast Asia — and we can typically get your first expansion market live in 4-6 weeks.
