New website for an international arbitration and corporate law firm in Tokyo: real cost vs local agencies (2026)

The verdict in three sentences

For an international arbitration and corporate law firm in Tokyo, a new website from a local agency typically costs 2 to 5 million JPY (about 13,000 to 33,000 USD), and the city's premium studios quote well above that. Kolonell works on a fixed grid in dollars: Starter 2,900 USD, Growth 4,900 USD, Premium 8,900 USD, with native English or French copywriting, a project manager reachable during Tokyo business hours and delivery in 3 to 6 weeks. The real decision is less about the build price than about who writes the partner profiles, seat experience and Japanese content with the rigor general counsel expect.

What does an arbitration firm website really cost in Tokyo in 2026?

The yen ranges are prudent 2026 ballparks drawn from typical local agency quotes and public rate pages, converted at roughly 150 JPY to 1 USD. Kolonell prices are never converted: they are set in dollars for this market. Tier details are on the international offer page.

What the site must prove to general counsel and boards

The general counsel of an industrial group, a board or a state entity does not choose an arbitration firm from a home page. They check partner reputation, the seats where partners have appeared, the rules they practise under (ICC, LCIA, SIAC, HKIAC, ICSID, JCAA), the languages of proceedings and sector experience. The site has to make all of that verifiable in under a minute.

Pages to plan for a firm in Marunouchi or Toranomon:

• Partner and counsel profiles: bar admissions, bengoshi or registered foreign lawyer status in Japan, working languages, roles (counsel, arbitrator, expert).
• Commercial and investment treaty arbitration: types of disputes handled, sectors (energy, construction, joint ventures, M&A), never naming a matter without authorization.
• Cross-border corporate work: inbound investment into Japan, joint ventures, post-acquisition disputes.
• Insights: dated, signed notes on changes to arbitration rules.
• Contact and intake: a minimal form that works with your conflict-check process.
• Privacy notice: purposes of use in line with the APPI, Japan's Act on the Protection of Personal Information, supervised by the PPC.

Lawyer advertising in Japan is governed by bar association rules, and the Japan Federation of Bar Associations publishes rules on lawyer advertising. A firm with partners admitted in New York or England must also respect those bars' rules. This is not legal advice: final review of the content belongs to your professional responsibility partner.

Kolonell built the website of TR Signing Group (trsigninggroup.com), a signing services company in New Jersey: a different trade, with the same need to look precise and trustworthy to legal professionals.

Hidden costs and the three-year total

The Kolonell math: 8,900 + 2,000 + 1,000 + 6,600 = 18,500 USD at the low end, 8,900 + 5,000 + 2,500 + 19,800 = 36,200 USD at the high end. The gap comes mostly from the build; translation and maintenance weigh about the same on both sides.

When a Tokyo agency is the better choice

To be candid: if your main clients are Japanese general counsel who read Japanese first, a local agency able to write formal legal Japanese with the right level of keigo brings value that outside translation does not always match. The same applies if procurement requires a domestic vendor invoicing in yen, or if you want in-person workshops at your offices. Kolonell fits when English is the firm's reference language and Japanese comes second, handled by a legal translator.

Questions to ask any provider:

• Who writes the partner profiles, and in which source language?
• Does the contact form limit the data collected before conflict checks?
• Who owns the domain, the CMS and the hosting accounts?
• How is the Japanese version handled: translation, review, updates?
• What does maintenance cost after the included period, and what does it cover?

Mini case study

Illustrative example: Kanda Ridge Partners, a fictional five-partner firm in Marunouchi focused on construction and energy arbitration. The managing partner receives a local agency quote of 3,800,000 JPY, about 25,300 USD. She compares it with Kolonell Premium, the multilingual tier, in English and Japanese set in the quote, at 8,900 USD, plus a Japanese legal translation at 3,200 USD (market assumption) and a photo session at 1,400 USD (market assumption). Year-one total: 8,900 + 3,200 + 1,400 = 13,500 USD, about 11,800 USD below the local quote. She keeps the local agency in mind for Japanese-language press relations.

FAQ

How much does an arbitration firm website cost in Tokyo in 2026?

A mid-size local agency typically quotes 2 to 5 million JPY, about 13,000 to 33,000 USD. At Kolonell the grid is fixed: 2,900, 4,900 or 8,900 USD depending on the tier.
