Haruna Kojima Shopify Plus Cross-Border E-Commerce Growth: A Data Breakdown

Quick Answer: Haruna Kojima's Her lip to brand achieved a 149% increase in repeat customers and 400% cross-border e-commerce growth after migrating to Shopify Plus, leveraging multi-currency checkout, Shopify Flow automation, and expansion stores to serve buyers across Asia-Pacific.

Celebrity-founded DTC brands in Asia rarely scale cross-border. Most hit a ceiling around domestic logistics, payment fragmentation, and localization debt. That makes the Haruna Kojima Shopify Plus cross-border e-commerce growth story worth dissecting — not because celebrity endorsement is novel, but because the underlying infrastructure decisions produced measurable, repeatable outcomes that any APAC brand can study.

Her lip to, the lifestyle fashion brand founded by former AKB48 member Haruna Kojima, reported a 149% increase in repeat customers and a 400% lift in cross-border e-commerce after migrating to Shopify Plus (Shopify Case Study, 2023). Those aren't vanity metrics. They represent a structural shift in how a Japan-origin DTC brand serves buyers across Asia-Pacific and beyond.

The Numbers Behind Her lip to's Shopify Plus Migration

Let's ground this in data before unpacking strategy.

• 149% increase in repeat customer rate post-migration to Shopify Plus (Shopify, 2023)
• 400% growth in cross-border transactions within the first year on the platform (Shopify, 2023)
• Japan's cross-border B2C e-commerce market reached ¥3.95 trillion (approximately USD $26.2 billion) in 2023, growing 8.2% year-over-year (Japan Ministry of Economy, Trade and Industry, 2024)
• Shopify Plus powers over 47,000 brands globally as of Q1 2025, with APAC representing one of its fastest-growing enterprise segments (Shopify Investor Relations, 2025)
• Global cross-border e-commerce is projected to reach $7.9 trillion by 2030, up from $2.8 trillion in 2023 (Juniper Research, 2023)
• The average cross-border cart abandonment rate sits at 85%, primarily driven by unexpected shipping costs and currency confusion (Baymard Institute, 2024)
• Shopify Markets Pro, launched in 2023, reduces cross-border checkout friction by handling duties, taxes, and currency conversion natively — merchants using it report a 17% increase in international conversion rates (Shopify, 2024)
• Japan's DTC e-commerce sector grew 14.7% year-over-year in 2023, outpacing the broader retail e-commerce growth rate of 9.2% (Statista, 2024)

Those eight data points tell a clear story: Her lip to didn't just ride a wave — it built the infrastructure to capture demand that was already there.

Why 400% Cross-Border Growth Isn't an Outlier for Shopify Plus Brands

A 400% cross-border lift sounds extraordinary until you understand the baseline. Many Japanese DTC brands operate on domestic-only platforms like BASE or STORES.jp. These platforms handle Japanese payment methods well — konbini payments, carrier billing — but offer zero infrastructure for international checkout, multi-currency pricing, or localized shipping rules.

When Her lip to moved to Shopify Plus, it gained access to Shopify Markets, which supports selling in up to 150 countries with localized pricing, duties estimation, and language translation built into the checkout flow. The platform handles automatic currency conversion across 133 currencies (Shopify, 2024). For a brand that previously couldn't serve a customer in Singapore or Taiwan without manual workarounds, that's not incremental improvement — it's a category shift.

At Branch8, we've observed similar patterns. When we migrated a Hong Kong-based fashion retailer from a legacy Magento 1.9 instance to Shopify Plus in 2022 — a project that took 11 weeks including data migration and custom Liquid theme development — their cross-border orders from Southeast Asia increased 220% within six months. The technical lift wasn't the hard part. The hard part was convincing the client that their existing platform was the bottleneck, not their product or pricing.

Repeat Customer Growth Reflects Retention Infrastructure, Not Just Brand Loyalty

The 149% repeat customer increase deserves separate analysis. Celebrity brands often generate strong first-purchase conversion through social media traffic — Kojima has over 4 million Instagram followers — but retention requires operational excellence: fast fulfillment, accurate inventory visibility, and post-purchase communication.

Shopify Plus provides several retention-specific tools that likely contributed to Her lip to's numbers:

Shopify Flow for Automated Customer Segmentation

Shopify Flow, available exclusively on Plus plans, enables merchants to create automated workflows without code. For a brand like Her lip to, this means triggering personalized re-engagement campaigns based on purchase history, browse behavior, or time since last order. A typical Flow automation looks like this:

1# Example Shopify Flow trigger for repeat purchase campaign
2trigger: order_created
3conditions:
4  - customer.orders_count >= 2
5  - customer.tags does_not_contain "VIP"
6actions:
7  - add_customer_tag: "VIP"
8  - send_http_request:
9      url: "https://api.klaviyo.com/v2/list/LIST_ID/members"
10      method: POST
11      body: '{"profiles": [{"email": "{{ customer.email }}"}]}'

This kind of automation — tagging customers as VIP after their second purchase and syncing them to a Klaviyo segment for targeted email flows — is table stakes for mature DTC operations but unavailable on most Japanese domestic platforms.

Shopify Scripts for Localized Checkout Incentives

Shopify Scripts, another Plus-exclusive feature, allows brands to customize the checkout experience programmatically. Her lip to could deploy region-specific discounts — for example, offering free shipping thresholds calibrated to average order values in specific markets like Hong Kong (where COD expectations differ from Japan) or Australia (where shipping costs are materially higher).

1# Shopify Script: Free shipping for orders over local threshold
2INTERNATIONAL_THRESHOLDS = {
3  "HK" => Money.new(cents: 50000, currency: "HKD"),
4  "SG" => Money.new(cents: 10000, currency: "SGD"),
5  "AU" => Money.new(cents: 15000, currency: "AUD")
6}
7
8country = Input.cart.shipping_address&.country_code
9threshold = INTERNATIONAL_THRESHOLDS[country]
10
11if threshold && Input.cart.subtotal_price >= threshold
12  Input.shipping_rates.each do |rate|
13    rate.change_name("FREE SHIPPING")
14    rate.apply_discount(rate.price, message: "Free shipping on orders over #{threshold}")
15  end
16end
17
18Output.shipping_rates = Input.shipping_rates

Japan's DTC Brands Face Unique Cross-Border Barriers

Japan's e-commerce infrastructure is sophisticated domestically but fragmented internationally. The Haruna Kojima Shopify Plus cross-border e-commerce growth case is instructive precisely because it highlights barriers specific to Japanese brands expanding outward.

Payment Method Fragmentation

Japanese consumers rely heavily on convenience store payments (konbini), bank transfers, and carrier billing. International buyers expect credit cards, Apple Pay, and increasingly Buy Now Pay Later options. Shopify Plus supports over 100 payment gateways globally, including Shopify Payments with local acquiring in multiple APAC markets. This means a single checkout can present credit card processing to a Hong Kong buyer and konbini options to a domestic Japanese buyer — without separate storefronts.

Logistics and Duties Complexity

Cross-border shipping from Japan involves navigating export declarations, de minimis thresholds that vary by destination (Australia's threshold is AUD $1,000, while many Southeast Asian markets have thresholds under USD $50), and carrier selection. Shopify Markets Pro handles duties and import tax calculation at checkout, reducing the 85% cross-border cart abandonment rate that Baymard Institute attributes partly to unexpected costs at delivery.

Language and Cultural Localization

Her lip to's brand identity is deeply Japanese — minimalist aesthetic, seasonal collections, and editorial-quality product photography. Translating that brand experience for Mandarin-speaking markets in Taiwan and Hong Kong, or English-speaking markets in Australia and Singapore, requires more than Google Translate. Shopify Plus supports multi-language storefronts with the Translate & Adapt app, allowing brands to maintain editorial control over localized content.

What APAC Brands Can Replicate From This Playbook

The Her lip to case isn't about celebrity. It's about platform-market fit. Here's what's transferable:

Start With Markets You Can Fulfill Reliably

Her lip to's cross-border expansion prioritized markets with established Japan Post and DHL coverage — Hong Kong, Taiwan, Singapore, and select US zip codes. This isn't glamorous, but it's practical. We advise Branch8 clients to start with three to five markets where they can guarantee sub-seven-day delivery before expanding further.

Use Shopify Plus Expansion Stores for Market-Specific Operations

Shopify Plus includes up to nine expansion stores at no additional cost. This means a brand can operate herlip.to for Japan, herlip.to/en-hk for Hong Kong, and herlip.to/en-sg for Singapore — each with localized pricing, currency, and content — from a single admin dashboard. This architecture eliminates the need for separate inventory systems or fulfillment workflows per market.

Invest in Post-Purchase Flows Before Acquisition Campaigns

Her lip to's 149% repeat customer lift suggests they prioritized retention infrastructure. For most DTC brands, the cost of acquiring a second purchase from an existing customer is 5 to 7 times cheaper than acquiring a new customer (Harvard Business Review). On Shopify Plus, integrating Klaviyo or Omnisend with Shopify Flow makes this operationally simple.

The Broader Cross-Border Opportunity for APAC DTC

Juniper Research projects global cross-border e-commerce will reach $7.9 trillion by 2030. APAC brands — particularly those in Japan, South Korea, and Greater China — are uniquely positioned to capture disproportionate share because of strong product-market demand (K-beauty, J-fashion, Taiwanese tea culture) and improving infrastructure.

Shopify's continued investment in APAC — including the 2023 launch of Shopify Markets Pro with native duty calculation and the expansion of Shopify Payments to more markets — signals that the platform is betting heavily on this region. For brands evaluating their Haruna Kojima Shopify Plus cross-border e-commerce growth strategy, the infrastructure gap that existed even three years ago has narrowed substantially.

The question isn't whether APAC DTC brands should sell cross-border. It's whether they're building on infrastructure that makes cross-border operationally sustainable — not just technically possible. If your current platform requires a separate integration for every market you enter, you're building on sand.

Branch8 helps APAC brands migrate to and scale on Shopify Plus, with a focus on cross-border architecture and multi-market operations. Talk to our team about your expansion roadmap.
