Shopify support for the Japan market
Shopify Japanwithout the language gap.
I help ecommerce brands run Shopify in Japan or from Japan to overseas — setup, localization, copy, market readiness, and the ads and tracking layer behind it. One bilingual partner in Tokyo, instead of three handoffs.
Tokyo-basedEN / JP bilingualShopify build + growth
Who this is for
Overseas brands selling into Japan
You want a Japanese-language store that actually reads naturally to local shoppers — not a translated version of your global site.
Japanese brands going outbound
You need an English experience that helps overseas customers buy without losing the Japanese-market store you already trust.
Founders without a JP-side partner
You don't have someone bilingual on the team to brief, review, and own the Japanese side of your Shopify and growth work.
What I cover
One workflow for Japan-market Shopify growth.
Store foundation
Shopify setup & localization
Theme setup, navigation, product taxonomy, multi-currency, geolocation routing, and a JP-first storefront experience that doesn't feel translated.
EN / JP communication
Direct bilingual communication with you, your team, suppliers, agencies, and JP-side stakeholders so requirements don't get lost in translation.
Market readiness
Product & page copy support
Product page copy, landing pages, and brand story sections written for the Japanese market — clear pricing logic, trust cues, and supplement-/regulation-safe wording where needed.
Market readiness review
Pre-launch and ongoing reviews of pricing presentation, payment options, shipping clarity, JP-side trust signals, and what local shoppers expect from a serious store.
Growth execution
Ads, tracking & creative support
Meta and Google Ads setup, conversion tracking via GA4 and the Shopify pixel layer, and creative direction tied to actual funnel performance — not vanity metrics.
Continuous improvement
Weekly funnel reviews from homepage to checkout, small UI/UX fixes, and reporting that turns into the next decision instead of sitting in a deck.

How it usually starts
01
Project fit check
Tell me your store, market, and goal. I review the context and reply with the clearest next step — not a generic proposal.
02
Scope & sequence
We agree on what to build, fix, or test first. Setup work and growth work are sequenced so spend doesn't run into a leaky funnel.
03
Build, ship, review
I deliver the work, monitor the funnel weekly, and make the next move based on what the data is actually showing.

Common questions
Do you only work with Japanese-language stores?
No. The page is called Shopify Japan because Japan is involved in some way — either you're selling into Japan, you're a Japanese brand going outbound, or you need someone bilingual to bridge both sides. English-only stores with a Japan link are still a fit.
Can you handle paid ads as well as the build?
Yes. Paid ads, tracking, and creative direction are part of the same workflow. They're often paused at the start so the storefront and tracking are ready before spend ramps up.
Do you redesign the whole theme or work within Shopify settings?
Both are possible. Most projects stay within standard Shopify and theme settings to keep ownership simple. Full custom theme work is scoped separately when it's actually needed.
How do we communicate day to day?
Usually WhatsApp or email for quick approvals, with a short weekly update covering what was done, what worked, and the next move.
