Choose web design agencies in Tokyo by the problem they can solve: entering Japan, rebuilding an existing Japanese site, or maintaining a bilingual business platform. A research studio and a production agency may both be valuable, but they are not interchangeable. Start with the audience and operating requirements, then compare proposals against the same deliverables.

A good shortlist should explain why each company belongs on it. The examples below are selected for their published services and different working models, not personal testing, verified client satisfaction or a claim that they are the city's three best agencies.

Decide whether you need discovery, a build, or both

Before requesting a quotation, write one page describing who will use the site, what they should accomplish and what prevents that today. For a hotel, the problem might be visitors abandoning an external booking engine. For an international supplier, it might be Japanese prospects not understanding the offer or finding the right enquiry route. Those call for different investigations.

A redesign is not automatically the first step. When the business proposition itself is unclear to the intended audience, commission research or a prototype test before paying for a complete production site. Conversely, a company with validated content and a straightforward publishing requirement may need disciplined implementation more than an extensive discovery programme.

Ask each prospective partner to separate what it knows from what it proposes to test. "Japanese users prefer this" is not a sufficient justification for every design decision. A useful proposal identifies the relevant audience, the evidence and the consequences for your particular service.

Three different partners to investigate

Humble Bunny publishes Japanese web-design and landing-page-optimisation services, with Japanese-market specialists and English-language support. It is a relevant conversation for an international brand that needs to connect a website with acquisition and conversion work. Ask how its proposed design decisions will be tested, and whether the quotation includes content, implementation and ongoing optimisation or only selected stages. 1

AQ offers user research in Japan, including usability testing, prototype localisation and reporting in English or Japanese. That makes it a useful candidate when understanding users is the unresolved problem. Its research offering is not, by itself, proof that a quotation will include every development, hosting and maintenance responsibility. Establish who would turn the findings into the finished site. 2

Upgrade Inc. describes a web-design and digital-marketing practice supporting businesses entering Japan. Its company page also explains that it works with a Philippines-based team in English. That is a delivery model to discuss, not a reason to accept or reject it automatically: ask who manages the project, who reviews Japanese copy and who is accountable for releases. 3

Request a relevant example from each finalist. A visually impressive campaign page does not establish experience with a large multilingual catalogue, and a complex software interface does not necessarily demonstrate persuasive hospitality content. Ask what the agency actually supplied on the example, rather than assuming everything bearing a client's name was its work.

Treat Japanese content as a workstream

The content brief should identify the source language, who writes each version and who approves meaning. Separate translation from adapting the message. You might need to explain a product category, change supporting examples or reorder questions, rather than translate an English page sentence by sentence.

Give the agency a difficult real page to discuss: a cancellation policy, technical specification or booking form. Ask how it would resolve ambiguous terminology and maintain consistency across headings, navigation and transactional messages. This reveals more about bilingual delivery than an introductory conversation conducted fluently in English.

For multilingual search, Google's documentation recommends separate URLs for different language versions and explains the role of language annotations. Ask the supplier to show the intended URL structure and how equivalent pages will be connected. Do not accept a language switcher screenshot as evidence that the underlying implementation is complete. 4

Also decide what happens when only one language is updated. A site needs an editorial owner, a translation queue and a visible way to identify stale content. Without that operating process, even a well-built bilingual launch can drift into two different versions of the business.

Make competing quotations comparable

Give every shortlisted agency the same inventory: page types, approximate content volume, languages, integrations and editorial roles. Specify whether existing material can be reused. A quotation for ten designed templates is not directly comparable with one for ten individually entered pages.

Ask for separate figures for discovery, design, development, content migration, testing and post-launch support. This is a procurement recommendation, not an estimate of Tokyo market prices. The useful comparison is the cost of the complete agreed scope, including work your own team must still perform.

Define what "integration" means. Does the supplier merely link to a booking engine, embed it, exchange data with it or redesign part of the transaction? Who investigates a failure involving two vendors? Put that responsibility in writing before a launch date depends on it.

A smaller first release can be sensible. For example, launch the core Japanese service pages and a working enquiry flow before migrating a large archive that attracts little relevant traffic. However, make that a deliberate scope decision; do not discover after signing that migration and redirects were excluded.

Test the working site, not just the presentation

Ask to review a staging version with real content, long Japanese headings and representative images. Try the enquiry or purchase journey on a phone. Have the person who will maintain the site edit a page, replace an image and recover an earlier version while the agency observes.

Accessibility should have a named target and an agreed testing method. W3C's Web Content Accessibility Guidelines provide testable requirements; a vague promise of an "accessible design" is less useful than specifying which standard and level form part of acceptance. Keyboard operation, form labels and meaningful error messages deserve explicit attention. 5

Test failures as well as success. What appears when a form submission fails, a product is unavailable or a language version has no equivalent page? Decide who receives operational alerts. A polished homepage cannot compensate for a contact form that silently loses enquiries.

Keep ownership and maintenance clear

Arrange for the business to control the domain, hosting relationship, analytics and essential third-party accounts. Give the agency the access it needs without making a departing contractor the only person able to administer the site.

The handover should identify the code repository, design files, licences, backup process and maintenance responsibilities. Clarify which components require paid renewals and what happens when support ends. These are contract questions to resolve with your advisers, not assumptions about rights automatically included in a design fee.

Choose the partner whose proposal makes the difficult decisions understandable. The strongest outcome is not simply a new website: it is a site your intended users can navigate, your team can operate and your next supplier can inherit without starting again.
