What To Check First

Vetting a legal & law firms mobile app developer in Tokyo

Here's how to tell a real legal & law firms specialist apart from a generalist agency that only adds your sector to its homepage once you're signed.

SRA Transparency Rules compliance: price indication for all six mandated service areas displayed clearly-not hidden in a PDF or buried in footer text

Solicitor/barrister profile pages with SRA registration numbers, call to the bar dates, and specialisation areas-supports E-E-A-T signals and client trust

Inquiry form design with clear matter type classification: routing different inquiry types to the correct fee earner is a conversion and compliance issue

Legal Ombudsman and SRA badges displayed correctly-check placement and link accuracy; incorrect or outdated badge display is a common SRA audit finding

Content E-E-A-T: legal article authors must be named qualified fee earners with listed specialisms-ghost-written 'thought leadership' with no named author scores poorly with Google's legal YMYL classifier

Platform Choices

Which platform suits legal & law firms apps in Tokyo?

Custom WordPress

The most common stack for Tokyo law firms. Attorney/solicitor profile custom post types, practice area taxonomy, and case study pages managed by practice managers without developer involvement. Must be custom-themed for SRA compliance display.

Next.js + Contentful

Preferred for multi-practice firms, chambers, and international law firm offices in Tokyo requiring performance-optimised practice area pages, multi-author article publishing, and CRM integration.

Clio Grow / Lawmatics embed

Legal CRM intake forms. These embed into any website and route inquiry data directly into the firm's matter management system. Should be used by any Tokyo firm with more than 4 fee earners.

LexBlog (barrister chambers)

A specialist legal blogging platform used by UK barrister chambers. Provides SRA-aware template structures and a content community. Consider for chambers with high blog publishing volume.

Common Questions

Legal & Law Firms mobile app questions from Tokyo businesses

What legal & law firms companies in Tokyo tend to ask before greenlighting an app project.

What are the SRA Transparency Rules requirements for a Tokyo law firm website?+

SRA-regulated firms in Japan must publish indicative prices for six service areas: residential conveyancing, probate, contested probate, motoring offences, employment tribunal claims (unfair/wrongful dismissal), and immigration (settlement applications)-where those services are offered. They must also display the complaint process, a link to the Legal Ombudsman, and the SRA Digital Badge. These are minimum requirements; the SRA web page guidance provides the full specification.

How much does a law firm website cost in Tokyo?+

A sole practitioner or small firm website with SRA compliance display costs £2,500–£7,000 in Tokyo. A multi-practice firm with full practice area SEO, fee earner directory, and blog is £7,000–£22,000. Barrister chambers websites are £8,000–£25,000. A Tokyo office of an international firm with multi-jurisdiction pages and CRM integration is £20,000–£75,000.

Should a Tokyo law firm invest in SEO alongside the new website?+

Legal keyword categories-'solicitors near me', conveyancing, personal injury, employment-are among the most competitive in Google's paid and organic results. A new law firm website in Tokyo without an SEO strategy will rank on page 4 or lower within 6 months. Law firm SEO requires long-form practice area pages of 1,500+ words targeting specific query types, structured data for legal services, and local citation building in Tokyo.

What should a Tokyo business look for in a contract before hiring a web developer?+

A properly scoped web development contract for a Tokyo business should include: a fixed-price quote (not hourly with uncapped scope), a detailed scope of work document, a timeline with specific milestones and delivery dates, ownership of all source code and assets on completion, a warranty period of at least 30 days post-launch for bug fixing, and clear terms for revision rounds. Avoid any contract that includes a retainer obligation as a condition of handover — this is a red flag in the Tokyo web development market.

How long does a Tokyo web project typically take from brief to launch?+

A standard business website for a Tokyo company takes 2–4 weeks from brief to launch (assuming content is provided on time). A custom web application with integrations typically takes 6–12 weeks. E-commerce sites with product catalogue setup take 3–8 weeks. The most common cause of delays in Tokyo web projects is late content delivery from the client — agree a content deadline before the project starts and the timeline holds reliably.

Should a Tokyo business hire a local web developer or work with a remote agency?+

For most Tokyo businesses, a remote web development agency delivers equivalent or better results than a local studio — at 20–40% lower cost. The key factors are: quality of portfolio (verifiable through live URLs, not PDF screenshots), communication responsiveness (same-day replies are the baseline for professional agencies), and clear ownership transfer on handover. Physical location has not been a meaningful differentiator for web development quality since 2018. Tkist Digital serves clients across Japan and 40+ countries entirely remotely.

How can a Tokyo business verify a web developer's experience before signing?+

The three most reliable verification methods for Tokyo businesses evaluating web developers are: 1) Live portfolio links — the agency should provide direct URLs to live sites they built (not PDF mockups), which you can test for speed, mobile quality, and design; 2) Client references — ask for contact details for two recent clients in a similar sector; 3) Technical audit — ask the developer to explain how they would handle a specific technical challenge for your project. A developer who cannot answer this clearly has not built what they claim. Tkist Digital provides live portfolio URLs, verified client references, and a free technical scoping call for every Tokyo project enquiry.
