01How we build

Watch a website come together

Five stages, one team, no hand-offs between agencies. Scroll to see each stage take shape.

  1. 01

    Discover

    We map your goals, users and the pages that earn money before anyone opens a design tool. You get a sitemap, a content plan and a fixed-price scope.

    sitemap.json
  2. 02

    Wireframe

    Every page is laid out in grey first, so structure, copy hierarchy and calls to action are agreed before colour gets in the way.

    Design

    Your brand becomes a design system: type, colour, spacing and components that stay consistent as the site grows.

    Launch

    Performance budgets, accessibility checks and SEO migration run before go-live. Then we watch real-user metrics and keep improving.

    Metadata, structured data, redirects, GA4 and conversion tracking set up before launch.

03Performance

Speed is a feature your customers feel

Most visitors in Tokyo reach you on a phone, often on a mobile network. We set a performance budget before we write code and test against it on every release.

05Built for Tokyo

Websites that read naturally in Japanese

Japanese users expect detail, precision and speed. Getting the language and typography right is where most international agencies fall short.

  1. Japanese typography

    Subsetted Japanese web fonts, correct line-breaking rules and comfortable line heights, so pages look right and still load fast.

  2. Mobile first, really

    Layouts, forms and checkouts are designed for phones first, because that is where most Tokyo visitors arrive.

  3. Local integrations

    Convenience store and QR wallet payments, LINE sharing and forms that handle Japanese names and addresses properly.

06FAQ

Web development in Tokyo: questions we hear

Do you build websites in Japanese and English?

Yes. We design bilingual sites from the start, with separate layouts where the languages need them, proper hreflang tags and a CMS that lets your team manage both versions.

How do you handle Japanese fonts without slowing the site?

Japanese fonts are large, so we subset them, load them in stages and fall back to system fonts while they arrive. Text stays readable immediately and the page stays fast.

Can you integrate Japanese payment methods?

Yes. We integrate payment providers that support Japanese methods such as convenience store payments, bank transfers and popular QR wallets, alongside cards.

How do you work with clients in Tokyo?

We work remotely with scheduled calls in Japan Standard Time, shared project boards and milestone reviews, so you see progress every couple of weeks.

How long does it take to build a website?

A marketing website usually takes six to ten weeks including bilingual content. Web applications and e-commerce builds are delivered in milestones.
