信頼と成果を生むウェブサイト設計 / A Website Engineered for Trust, Credibility, and Conversion

Japanese businesses require websites that communicate institutional credibility before a visitor decides to enquire. Company registration details, representative names, postal addresses, and clear corporate information are not optional additions. They are the structural foundation of a site that converts in the Japanese market.

日本語・英語バイリンガル対応 / Bilingual JP and EN builds available · 法人番号・代表者名・所在地の掲載に対応 / Company legal info structured and integrated · APPI (個人情報保護法) compliance built in · 8 to 12 week delivery from signed brief to launch · Built for companies serving both Japanese and international markets
This is for you if

This service is for companies operating in Japan or entering the Japanese market that understand the website is a trust document, not just a sales tool.

You have been operating for years. Your current website was built by a local web production company and looks like every other site in your category. Prospective clients check your site before meetings. What they find should match the credibility of your actual business. Outdated layouts and missing corporate information undermine trust before you have said a word.

You are entering the Japanese market and your global website is not fit for purpose here. A direct translation of an English-language minimal site will not convert Japanese buyers. You need a Japan-specific build, or a Japan-specific section, that meets local expectations for information, formality, and credibility markers.

You need a bilingual site that does not read like a translation. Japanese visitors expect Japanese-native content, not rendered English. International visitors expect a professional English-language site. Both language versions need to be purpose-built, not one translated from the other.

What's broken

Four structural problems common to corporate websites in the Japanese market.

Missing or incomplete corporate information

In Japan, the absence of a legal registration number (法人番号), a physical address, a representative name, and a direct phone number is interpreted as a trust signal failure. Japanese buyers look for these details as a standard verification step. If they are missing or buried, the enquiry does not happen.

Western minimal design applied to a Japanese audience

Minimal, image-heavy, low-text layouts can perform well for international audiences. They perform poorly with Japanese buyers unless the company is explicitly positioning for international clients. Information density is expected. A sparse site communicates incomplete information, not confident restraint.

Bilingual builds that are just translated pages

Running a machine translation of English content and calling it a Japanese site is visible immediately to Japanese readers. Phrasing is unnatural, keigo (formal register) is absent, and the content structure does not match Japanese reader expectations. Bilingual builds require both languages to be written natively.

APPI compliance not addressed

Japan's Act on Protection of Personal Information requires a clearly stated privacy policy, consent for data collection, and defined procedures for handling personal data. Many corporate sites treat this as a minor footer item. In a market where compliance signals credibility, a properly structured privacy policy is part of the trust architecture.

What we engineer

Six deliverables structured for the Japanese market.

Discovery Session (Japanese and English)

A structured discovery session conducted in Japanese or English (or both) covering your business, your buyers, your competitive landscape, and the trust signals your specific audience expects. We review your current corporate information structure and identify what is missing.

Sitemap and Information Architecture

We map the full page structure for both language versions if bilingual, define user journeys for Japanese and international visitors separately, and plan the corporate information hierarchy. In Japan, the kaisha annai (会社案内 / Company Profile) section is not a secondary page. It is a primary trust destination.

Wireframes for Both Language Versions

Layout blueprints for every key page in both JP and EN. Japanese and English layouts often differ structurally because reading patterns, information expectations, and visual hierarchy conventions differ between the two audiences. We do not apply one layout to both.

Design System with Japanese Typography Standards

A complete visual design system including Japanese and Latin typefaces, spacing rules calibrated for Japanese character density, colour and component standards, and corporate identity integration. Japanese body text requires different line-height and character-spacing settings than Latin text.

CMS Development with Corporate Information Architecture

Built on WordPress, Webflow, or a custom stack. Every build includes: legal registration number (法人番号) display, representative name, postal address, phone number in header, certifications and accreditations section, and APPI-compliant privacy policy and consent framework.

Analytics, QA, and Launch Handover

Google Analytics 4 and Google Search Console configured for both language versions. Full QA across devices and browsers for both JP and EN. Launch-ready handover with CMS training in Japanese or English as required.

What changes

Four outcomes when a website is built correctly for the Japanese market.

Before
After
Before In Japan, the absence of a legal registration number (法人番号), a physical address, a representative name, and a direct phone number is interpreted as a trust signal failure. Japanese buyers look for these details as a standard verification step. If they are missing or buried, the enquiry does not happen.
After Japanese buyers do not enquire before they have verified the company. A site with complete corporate information, visible credentials, and clear contact details removes the verification barrier. Enquiries increase because the site answers the due diligence questions the prospect was going to ask anyway.
Before Minimal, image-heavy, low-text layouts can perform well for international audiences. They perform poorly with Japanese buyers unless the company is explicitly positioning for international clients. Information density is expected. A sparse site communicates incomplete information, not confident restraint.
After Japanese visitors read Japanese-native content in the correct register. English-speaking visitors read professional English. Neither audience encounters translated awkwardness. The site holds up under scrutiny from both directions.
Before Running a machine translation of English content and calling it a Japanese site is visible immediately to Japanese readers. Phrasing is unnatural, keigo (formal register) is absent, and the content structure does not match Japanese reader expectations. Bilingual builds require both languages to be written natively.
After For companies entering Japan, the website is often the first touchpoint with a prospective Japanese client, distributor, or partner. A site that reflects the correct cultural expectations of formality, completeness, and transparency signals that the company understands the market.
Before Japan's Act on Protection of Personal Information requires a clearly stated privacy policy, consent for data collection, and defined procedures for handling personal data. Many corporate sites treat this as a minor footer item. In a market where compliance signals credibility, a properly structured privacy policy is part of the trust architecture.
After A properly configured bilingual CMS means your Japanese and international content teams can update their respective language versions without breaking the other. No cross-language dependency, no developer calls for routine updates.

Common questions

Frequently asked questions about Website Design & Development

What corporate information is required on a Japanese business website?

Japanese websites are expected to display the company's legal registration number (法人番号), representative name (代表者名), postal address, phone number, and business registration details as minimum trust requirements. Many Japanese buyers will not enquire from a site that omits these. We structure this information into the build as standard for Japan-market clients.

Does information density in Japanese websites hurt conversions?

Information density is a feature in the Japanese market, not a flaw. Japanese buyers expect to find comprehensive company information, product or service details, FAQ sections, and process explanations on a single visit. A sparse site signals incomplete information. We calibrate information density to your specific audience and sector rather than applying a universal minimal standard.

How do you handle bilingual content?

We produce content architecture and wireframes for both language versions separately, because Japanese and English reader behaviour and information expectations differ. If you provide native-language copy in both languages, we implement both. If you need copywriting support in either language, that can be scoped as an add-on. We do not use machine translation as a final deliverable.

Is APPI compliance included in the build?

An APPI-compliant privacy policy framework and consent management structure are included in every Japan-market build. We integrate consent collection for analytics and contact forms, document data handling procedures, and structure the privacy policy page to meet the requirements of Japan's Act on Protection of Personal Information.

Can you build a site that serves both Japanese and international markets?

Bilingual JP and EN builds are one of our most common deliverables for Japan-market clients. The two language versions share a CMS but are structured independently, with separate layouts where required. Japanese and international visitors each receive a version purpose-built for their expectations, not a translation of the other.
