Haruna Kojima Shopify Plus Cross-Border Success: The Numbers

A Japanese apparel label built on a founder's personal following hits a ceiling that has nothing to do with demand. Orders come in from Taipei, Hong Kong, Singapore and Los Angeles. The storefront quotes prices in yen only, the checkout rejects half the cards, and shipping is quoted at a flat rate that either loses money or scares the customer away. The brand is not short of buyers. It is short of infrastructure.

That is the shape of the Haruna Kojima Shopify Plus cross-border success story. Her lip to, the fashion label founded by the former AKB48 member, reported a 149% increase in repeat customers and a 400% increase in cross-border e-commerce after adopting Shopify Plus, according to Shopify's published customer story. Those two numbers get quoted constantly. What almost nobody does is explain the mechanics behind them, or benchmark them against what a normal replatforming actually delivers.

That is what this piece does.

The headline finding: repeat rate moved more than acquisition

The most instructive part of the Her lip to result is which metric moved furthest in business terms.

A 400% cross-border increase is a top-line number off a small base — international was a rounding error before, and it became material after. A 149% lift in repeat customers is different. It compounds. It is applied to the entire customer file, not just the overseas slice.

Context for why that matters: repeat customers are consistently the cheapest revenue a DTC brand has. Shopify's own merchant data, published in its Commerce Trends research, has repeatedly shown returning customers converting at multiples of first-time visitors. Bain & Company's long-standing loyalty work — the origin of the widely cited finding that a 5% retention improvement can lift profit substantially — makes the same point from the P&L side (Bain & Company).

So the honest reading of the case is this: the cross-border number is the headline, the repeat number is the business.

Japan's cross-border demand was already there — the tooling wasn't

The demand side of this story is structural, not lucky.

Japan's B2C e-commerce market reached roughly ¥24.8 trillion in 2023, with apparel and accessories one of the largest goods categories, according to the Ministry of Economy, Trade and Industry's annual e-commerce market survey. METI's same survey tracks cross-border flows between Japan, the US and China, and consistently shows Chinese and US consumers buying substantially more from Japanese sites than the reverse.

In other words: overseas appetite for Japanese fashion brands is a documented, measured flow. The constraint on most mid-sized Japanese labels is not awareness. It is that their storefront cannot take the money.

Across APAC more broadly, the same asymmetry holds. Statista's e-commerce market data puts Asia-Pacific as the largest regional online retail market globally by revenue (Statista). A brand in Tokyo, Seoul or Taipei sits inside the demand pool. It just needs a checkout that behaves like a local one in each destination.

Four mechanics explain most cross-border lift after replatforming

When we look at cross-border revenue jumps after a Shopify Plus migration — in Her lip to's case and in the pattern we see across APAC engagements — the gains cluster around four mechanics. None of them are exotic.

Local currency pricing removes a visible tax on trust

Showing a Taiwanese shopper NT$ instead of ¥ is not cosmetic. Shopify's Markets documentation covers currency presentment, rounding rules and market-specific price adjustments as first-class settings (Shopify Help Center). Before Shopify Markets existed, most Japanese brands solved this with a third-party app, or not at all.

Local payment methods decide whether the order exists

Card penetration varies wildly across APAC destinations. Konbini and carrier billing matter in Japan, but a Japanese brand selling outbound needs the reverse: Alipay and WeChat Pay for Greater China, PayNow-adjacent rails in Singapore, buy-now-pay-later in Australia. The Worldpay Global Payments Report has tracked digital wallets overtaking cards as the leading global e-commerce payment method — a shift that is most extreme in Asia.

Duties and landed cost stop the post-purchase surprise

Unexpected charges at delivery are one of the most reliable causes of refund requests and one-and-done customers. Baymard Institute's ongoing checkout research puts average documented cart abandonment at 70.19%, with extra costs — shipping, fees, taxes — the single most cited reason (Baymard Institute). Duties-included checkout converts that from a nasty surprise into a line item.

Translated content that is actually maintained

Machine-translated product pages that drift out of sync with the Japanese source are worse than English-only. Shopify's Translate & Adapt and the Markets content model at least give you a maintainable structure.

A minimal market-aware price and currency block in Liquid looks like this:

1{%- assign market = localization.market -%}
2<span class="price" data-market="{{ market.handle }}">
3  {{ product.selected_or_first_available_variant.price | money_with_currency }}
4</span>
5
6{%- if localization.country.iso_code != 'JP' -%}
7  <p class="duties-note">
8    Duties and import taxes calculated at checkout for
9    {{ localization.country.name }}.
10  </p>
11{%- endif -%}

And checking which markets are actually live, via the Admin GraphQL API:

1query {
2  markets(first: 10) {
3    edges {
4      node {
5        name
6        enabled
7        primary
8        webPresence { defaultLocale { locale } }
9        currencySettings { baseCurrency { currencyCode } }
10      }
11    }
12  }
13}

Trivial code. The hard part is the merchandising and tax decisions behind it.

Benchmark honestly: 400% is not the expected outcome

This is where most write-ups of the Haruna Kojima Shopify Plus cross-border success go wrong. They present 400% as a benchmark. It is not. It is an outlier with specific preconditions.

Her lip to had three advantages that most brands do not:

1. Pre-existing international demand from founder reach. Haruna Kojima's audience predates the brand. Overseas fans were already trying to buy. The migration removed friction from demand that already existed — it did not create demand.
2. A small cross-border base. Percentage growth off a small denominator is dramatic. A brand already doing 25% of revenue internationally will not see 400%.
3. A product category with high repeat frequency. Fashion and lifestyle sustain repeat purchasing in a way that furniture or appliances do not.

For context on realistic ranges: Shopify reported roughly $292 billion in GMV across the platform for full-year 2024, and has stated that cross-border orders represent a mid-teens percentage of total orders (Shopify Investor Relations). That is the platform-wide baseline. A brand moving from 2% to 10% international revenue has done well. Moving from 2% to 10% is a 400% increase. Read the number in that light and it becomes credible rather than magical.

Replatforming pays for itself through operations, not just conversion

The part that rarely appears in case studies is cost.

Shopify Plus sits at a published starting point of roughly $2,300 per month on a three-year term, per Shopify's pricing page — before apps, before implementation, before the internal time cost of a migration. For a brand doing modest volume, that is a real line item.

The justification usually is not conversion rate alone. It is:

• Headcount avoided. Manual order routing, currency reconciliation and customs paperwork consume operations hours that scale linearly with international order volume.
• App consolidation. Markets, Translate & Adapt and native duties calculation replace three to five paid apps for most mid-market brands.
• Peak-load reliability. Drop-driven fashion brands — which Her lip to is — live and die on launch-day traffic. Shopify Plus's checkout throughput commitments matter more for a brand doing ten drops a year than for one with steady baseline traffic.

We worked with a Greater China lifestyle retailer whose original business case for Plus was written entirely around conversion uplift. It did not hold up under scrutiny. The case that did hold up was operational: the number of hours their finance team spent reconciling multi-currency settlements each month. That is a less exciting story and a more defensible one.

What APAC brands should actually measure post-migration

If you are building the business case for a cross-border replatforming, these are the metrics that tell you whether it worked — not the vanity ones.

• Repeat purchase rate by market, not blended. A blended 149% tells you nothing about whether Singapore or Hong Kong is the engine.
• Checkout completion rate by destination country. This isolates payment and duties friction from marketing quality. Compare against Baymard's ~70% abandonment baseline.
• Contribution margin per international order after duties, FX and returns. Cross-border revenue growth that destroys margin is not growth.
• Return rate by market. Sizing conventions differ across APAC. A market with strong revenue and a 40% return rate is a cost centre.
• Time-to-launch for a new market. On a properly configured Plus setup this should be days, not a quarter. If it is not, the migration under-delivered.

The Haruna Kojima Shopify Plus cross-border success is genuinely instructive — but the transferable lesson is the sequencing, not the percentages. Demand first, infrastructure second, and a repeat-rate metric you can defend to a CFO. The 400% is downstream of getting those three right.
