How Should a Multilingual Website Be Designed?

A common mistake is to assume that a Japanese website becomes clear once its copy is translated. Even accurate language will not help if the information order is confusing, controls are hard to find, or symbols carry an unfamiliar meaning. Users still cannot move confidently to the next action.

Translation should be the starting point for designing the full experience: seeing, understanding, choosing, and acting. The website shapes trust in the company and its services. Multilingual design is therefore a brand-experience task, not a language-only task.

“For international users” is too broad to guide design. Travelers and residents need different information, and first-time visitors encounter different barriers from repeat users. Start by stating who is using the site, where and on which device, what they need to understand, and what action they want to complete.

Then decide which languages and levels of detail are necessary. Do not translate everything with equal priority. Begin with information tied directly to action, such as emergency guidance, reservations, fees, and location. A specific audience definition also clarifies the interface structure and the ownership of ongoing updates.

Changing languages changes text length and line breaks. A compact box designed around Japanese may overflow in English and make headings or buttons difficult to read. Text embedded in images also makes translation and maintenance harder.

Use short sentences and communicate one idea at a time. Separate the roles of headings, explanations, and action buttons, and keep copy in editable text rather than images. Make the language switch easy to find on every page. A plain-Japanese option can also support machine translation and users who are still learning Japanese.

In the Hakodate Airport project, BOEL reframed the airport as the place where people first encounter Hakodate, rather than merely a transport facility. Flight and facility information was connected with tourism and regional guidance so that arriving visitors could imagine what to do next.

The same principle applies to multilingual websites. Fast access to essential information and a clear sense of the company or place should not be designed separately. When function and impression form one path, the experience can build reassurance and anticipation at the same time.

Colors and symbols may appear to communicate without words, but their meaning changes across cultures and experiences. A familiar Japanese sign may suggest something different elsewhere. Color alone can also hide status information from people who cannot distinguish it reliably.

Pair important symbols with concise labels. Combine color, shape, and position so that no single cue carries the whole meaning. Then show the interface to intended users and ask what they think it means and where they would act next. Cultural consideration is not complete until the design includes a way to validate interpretation.

A multilingual website is not finished at launch. If Japanese pages are updated while other languages remain outdated, users cannot tell which information to trust. Machine translation can support operations, but people should review content related to fees, rules, and safety.

Before launch, ask users of each target language to complete the primary tasks. After launch, review pages with high exits, search terms, and inquiry topics. Assign who updates each type of information and when. A cycle of small tests, learning, and revision keeps the experience reliable.

The goal of a multilingual website is not to maximize the number of languages. It is to help people with different backgrounds understand essential information, make their own choices, and act with confidence.

BOEL believes language, interface, guidance, and operations should be shaped from one question: with whom does the company want to build a relationship, and what should that relationship feel like? Accurate translation, low-friction journeys, and recognizable behavior must work together. Their consistency creates a brand experience that can earn trust across cultures.
