Information Architecture for a Japanese–English Website That Goes Beyond Translation
Accurate translation matters on a Japanese–English website. It may not, by itself, give a first-time overseas reader the context needed to understand the organisation or service. Information architecture decides who is reading, what they need to understand first, and which pages should correspond across languages.
Translation, localisation and information architecture have different jobs
Translation expresses content in another language. Localisation adjusts expression and practical information for a reader. Information architecture establishes the order of information and the route to a decision. None makes the others unnecessary.
1. Set the first question for each audience
Overseas customers, partners and candidates may need background that a Japanese reader already understands. A person in Japan may instead need practical local information such as scope, location or a contact route first. For every language, write down what a first-time reader is trying to decide on that page.
2. Separate shared facts from added context
Company names, service scope, conditions and evidence often need to remain aligned. Business context, explanations of specialist language, FAQs and the next action can change in order or depth for the reader. The purpose is not a one-to-one page count; it is responsible management of the facts that matter.
3. Make page relationships and switching clear
Pages with the same job should be easy to reach through a language switcher. Where one language has a page with no exact equivalent, give visitors a natural way to understand the difference. For search engines, language-specific URLs and the technical implementation of corresponding-page relationships, including hreflang where appropriate, need careful checking.
4. Do not treat paired and language-specific pages as the same problem
| Example | Japanese–English relationship | Architecture check |
|---|---|---|
| Company information or the same service | Corresponding pages with the same job | Shared facts, audience context, switch destination and URL relationship |
| A Japan-only event or programme | May be genuinely language-specific | Audience, guidance needed in the other language, entry and return path |
| Overseas trade or recruitment guidance | May require a different structure from the Japanese page | Context, evidence and contact route needed by an overseas reader |
Matching page counts is not the goal, but neither is leaving gaps unexplained. Recording the audience, job, owner and switch destination helps distinguish an intentional difference from a missed update.
5. Build a review path that continues after launch
Agree who checks specialist terminology, organisation-specific facts and brand language; when a new Japanese page should be reflected in English; and how an untranslated page is handled. A visible owner and publication status are easier to sustain than a rush to translate everything just before launch.
Move from planning to operation in sequence
Use the Japanese–English website planning guide to set audiences, page scope and review ownership. Once the page structure is defined, establish roles and publication states with the bilingual CMS operations guide.

Starting with the existing site and material, we can distinguish the facts that should stay aligned from the context each audience needs.
