Haruna Kojima Shopify Plus Cross-Border Growth: How Her Lip To Hit 400%

Quick Answer: Haruna Kojima's Her lip to brand achieved 400% cross-border sales growth and 149% repeat customer increase after migrating to Shopify Plus, using Shopify Markets for multi-currency selling, Shopify Flow for retention automation, and localized checkout experiences across APAC markets.

A Japanese celebrity-founded fashion label posts 400% cross-border sales growth and a 149% lift in repeat customers within months of re-platforming. That's not a hypothetical—it's the documented outcome of Haruna Kojima's Her lip to after migrating to Shopify Plus (Shopify case study, 2023). For any DTC brand in Asia-Pacific weighing a platform move, those numbers represent a concrete benchmark worth dissecting.

What makes the Haruna Kojima Shopify Plus cross-border growth story especially instructive isn't the celebrity factor. It's the operational playbook behind it: a deliberate migration strategy, a multi-currency storefront architecture, and a retention engine built on Shopify Plus's native tools. Let me walk through how it worked—and what other APAC brands can replicate.

The Business Problem Behind the Platform Move

Her lip to launched in 2018 as a premium women's fashion brand targeting Japan's domestic market. Haruna Kojima, one of Japan's most recognized former AKB48 members, built a brand with strong organic demand but a technology stack that couldn't keep pace.

The original infrastructure created friction at every layer. Page load times were slow. International shoppers encountered currency confusion and checkout abandonment. According to Baymard Institute's 2023 research, the average cart abandonment rate in fashion e-commerce sits around 69.8%—and cross-border shoppers abandon at even higher rates when pricing isn't localized.

Her lip to needed three things simultaneously: faster domestic performance, a cross-border sales channel that didn't require a separate storefront, and a loyalty mechanism to turn one-time international buyers into repeat customers. That combination of requirements pointed squarely at Shopify Plus.

Why Shopify Plus Was the Right Platform for This Growth Plan

Not every platform migration delivers results this dramatic. The reason Shopify Plus worked for Her lip to comes down to three architectural advantages that matter specifically for cross-border APAC brands.

Shopify Markets for Multi-Currency, Multi-Language Selling

Shopify Markets—launched in late 2021 and significantly enhanced through 2023—lets merchants sell in local currencies and languages from a single store instance. For Her lip to, this meant a Japanese customer sees JPY pricing and Japanese-language content, while a customer in Hong Kong sees HKD, and a US-based buyer sees USD. No duplicate stores. No inventory sync nightmares.

According to Shopify's own data, merchants using Shopify Markets see an average 13% increase in conversion rates from international buyers simply by presenting local pricing (Shopify Markets documentation, 2023).

Checkout Extensibility and Shopify Functions

Shopify Plus merchants get access to checkout extensibility APIs, which means custom discount logic, localized payment methods, and region-specific shipping rules—all without forking the checkout. Her lip to could implement Japan-specific Konbini payment support alongside international credit card processing through a single checkout flow.

Shopify Flow for Retention Automation

The 149% repeat customer increase didn't happen by accident. Shopify Flow—Shopify Plus's no-code automation tool—enables post-purchase sequences, VIP tagging, and restock notifications that run without developer intervention. For a brand with limited engineering resources, this is the difference between "we should do retention marketing" and actually doing it.

Deconstructing the 400% Cross-Border Sales Increase

A 400% increase sounds enormous, and it is. But context matters. Her lip to was selling primarily to Japan pre-migration. Cross-border revenue was a small base, which means percentage growth is amplified. That said, a 4x multiplier on any revenue stream within months of a migration is operationally significant.

Here's what drove it, based on publicly available details from Shopify's case study:

Reduced Friction for International Shoppers

Localizing currency alone removes one of the top three reasons international shoppers abandon carts, according to a 2023 report by Flow Commerce. When Her lip to switched to presenting prices in local currencies with duties and taxes calculated at checkout, the drop-off rate for non-Japanese visitors fell sharply.

Faster Page Performance

Shopify Plus stores on the Online Store 2.0 architecture consistently benchmark faster than legacy custom-built storefronts. Google's Core Web Vitals data shows that sites loading in under 2.5 seconds (LCP) have 24% lower bounce rates compared to sites loading in 4+ seconds (Google Web Vitals report, 2023). For a fashion brand where product imagery is heavy, this performance gap translates directly to revenue.

SEO Visibility in International Markets

Shopify Markets generates hreflang tags automatically, telling search engines which version of a page to serve to which country. This is a technical detail that many custom builds get wrong. Proper hreflang implementation helped Her lip to appear in search results across multiple APAC markets without duplicate content penalties.

A quick example of what Shopify generates automatically:

1<link rel="alternate" hreflang="ja" href="https://www.herlipto.jp/" />
2<link rel="alternate" hreflang="en" href="https://www.herlipto.jp/en/" />
3<link rel="alternate" hreflang="zh-Hant-HK" href="https://www.herlipto.jp/zh-hant-hk/" />
4<link rel="alternate" hreflang="x-default" href="https://www.herlipto.jp/en/" />

Manually managing hreflang across markets is error-prone. Automation here is a genuine advantage.

How the 149% Repeat Customer Lift Actually Worked

Repeat purchase rate is the metric that separates sustainable DTC brands from one-hit wonders. According to Shopify's analysis of its merchant base, repeat customers spend on average 67% more than first-time buyers (Shopify Commerce Trends 2024).

Her lip to's Haruna Kojima Shopify Plus cross-border growth strategy leaned heavily on post-purchase retention. Here's the likely operational stack:

Automated Post-Purchase Flows

Using Shopify Flow, Her lip to could trigger personalized follow-up emails based on purchase category, geographic region, and order value. A first-time international buyer gets a different sequence than a returning domestic customer.

Customer Segmentation via Shopify Plus Tags

Shopify Plus's customer tagging system, combined with Flow automation, enables VIP tiers without a third-party loyalty platform. Customers hitting certain spend thresholds get tagged automatically, unlocking early access to drops or exclusive discount codes.

Localized Retention Content

An English-speaking customer in Singapore receives retention emails in English with SGD pricing. A Taiwanese customer sees Traditional Chinese with TWD. This isn't trivial—it's the kind of personalization that requires either a massive MarTech stack or a platform that handles localization natively.

What APAC DTC Brands Can Replicate From This Playbook

Her lip to's success isn't unique to celebrity brands. The operational principles apply to any APAC DTC company with international demand.

Start With a Single-Store, Multi-Market Architecture

Running separate stores per market is operationally expensive. Inventory fragmentation, duplicate content management, and inconsistent branding all compound over time. Shopify Markets or Shopify Markets Pro (powered by Global-e) lets you start with one store and expand.

At Branch8, we migrated a Hong Kong-based fashion brand from a custom PHP storefront to Shopify Plus in eight weeks. The brand had been running three separate store instances—one for Hong Kong, one for Taiwan, one for Southeast Asia. We consolidated everything into a single Shopify Plus store using Shopify Markets, which cut their monthly hosting and maintenance costs by roughly 35% while tripling the number of markets they could actively serve. The team went from managing three admin dashboards to one.

Invest in Retention Before Acquisition

Most brands over-index on paid acquisition. The Her lip to case study demonstrates that platform-level retention tools—automated flows, segmentation, localized re-engagement—can deliver outsized ROI. According to Harvard Business Review, increasing customer retention by 5% can increase profits by 25-95%. That math holds especially true in cross-border commerce, where customer acquisition costs are 2-3x higher than domestic.

Localize Beyond Language

Currency and language are table stakes. True localization means local payment methods (GrabPay in Southeast Asia, LINE Pay in Taiwan and Japan, Alipay in mainland China), local shipping carriers, and culturally relevant merchandising. Shopify Plus's payment gateway flexibility supports over 100 payment providers, making this operationally feasible.

Does This Growth Strategy Scale Beyond Fashion?

Absolutely. The cross-border growth pattern Her lip to demonstrated maps to any product category with international demand and high repeat-purchase potential: beauty, supplements, specialty food, home goods, and consumer electronics accessories.

Statista projects global cross-border e-commerce to reach $7.9 trillion by 2030, up from $2.1 trillion in 2023 (Statista, Cross-Border E-Commerce Worldwide, 2024). The APAC region is the fastest-growing segment of that market, driven by rising middle-class spending power in Southeast Asia and mature digital infrastructure in Japan, South Korea, and Australia.

The technical requirements remain consistent across categories: fast storefronts, localized checkout, automated retention, and clean international SEO. The Haruna Kojima Shopify Plus cross-border growth case just happens to be one of the cleanest documented examples of execution.
