The verdict in three sentences
A licensed fintech or digital asset firm in Tokyo typically receives website quotes of JPY 2 to 6 million (about USD 13,000 to 40,000) from a mid-sized local agency in 2026, and well above that from a premium studio. Kolonell builds the same kind of corporate site on a fixed grid: Growth at USD 4,900 for a full corporate site, Premium at USD 8,900 for the multilingual tier with Japanese and English set in the quote, delivered in 3 to 6 weeks with 3 months of support. The real cost question is elsewhere: who writes the Japanese copy, who checks every licence reference and risk statement, and what the portal or integrations will cost on top.
What a Tokyo fintech site must prove before anyone signs
Institutional counterparties, corporate treasurers and sophisticated users do not read a fintech homepage for inspiration. They open it to check facts, often in this order: is the firm registered, with which authority and under which number; who holds client assets and how; who runs the company; what the risks are. In Japan, crypto-asset exchange service providers must be registered with the Financial Services Agency, and the registration details should appear on the site exactly as held. Promotional language about returns has no place there.
A credible site for this niche usually needs these pages:
- Licences and registrations, with the exact names and numbers as they appear in the official register, in Japanese and in English.
- Custody and security: how assets are segregated, cold and hot storage policy, third-party audits where they exist.
- Leadership and governance: board, compliance officer, audit firm if public.
- Products and fees, with plain-language risk warnings next to each product.
- Privacy and data handling, consistent with the Act on the Protection of Personal Information (APPI), overseen by the Personal Information Protection Commission.
- Press and disclosures, dated, so that partners see an active, transparent firm.
Your compliance team and legal counsel decide what is said; the web partner builds pages that make review easy and leave no room for unapproved claims. This is not legal advice.
Tokyo agency quotes vs a fixed grid
Local figures below are a prudent 2026 ballpark based on typical agency quotes and public rate pages in Tokyo, converted at roughly JPY 150 to the dollar. Kolonell prices are fixed and quoted in USD only.
| Option | Typical budget (JPY) | Approx. USD | Delivery | Notes |
|---|---|---|---|---|
| Freelance designer and developer | JPY 0.5 to 1.5M | USD 3,300 to 10,000 | 6 to 10 weeks | Little compliance experience, single point of failure |
| Mid-sized Tokyo agency | JPY 2 to 6M | USD 13,000 to 40,000 | 3 to 5 months | Japanese copy and meetings in person |
| Premium Tokyo studio | JPY 8 to 20M+ | USD 53,000 to 133,000+ | 4 to 8 months | Brand work, motion, large teams |
| Kolonell Starter | n/a | USD 2,900 | 3 to 4 weeks | Compact corporate site |
| Kolonell Growth | n/a | USD 4,900 | 3 to 4 weeks | Fuller corporate site, richer features |
| Kolonell Premium | n/a | USD 8,900 | 4 to 6 weeks | Multilingual tier, languages set in the quote |
Every Kolonell tier includes a project manager reachable in your time zone, native English or French copywriting, and 3 months of support. Japanese copy is a third-party translation or transcreation cost, quoted separately, and a client portal, KYC flows or exchange integrations are on quote. Details are on the international offer page.
The costs nobody puts on the first page of the quote
| Hidden cost | Typical 2026 range | Who pays it |
|---|---|---|
| Japanese transcreation of 15 to 25 pages | JPY 400k to 1.2M (USD 2,700 to 8,000) | Third party, any option |
| Legal and compliance review of copy | JPY 300k to 1.5M (USD 2,000 to 10,000) | Your counsel, any option |
| Professional photography of team and office | JPY 200k to 600k (USD 1,300 to 4,000) | Third party |
| Security review or penetration test of forms | USD 3,000 to 12,000 | Specialist firm |
| Client portal, onboarding or exchange API | On quote | Scoped separately |
| Maintenance after launch | USD 150 to 600 / month (market assumption) | On quote at Kolonell |
The compliance line is the one firms underestimate most. Every revision of a product page goes back to review, so a site with clear page templates and a single place for risk warnings saves review hours for years.
Three-year view and when a local agency is the better choice
Over three years, the gap shrinks less than people expect. Take a bilingual corporate site with no portal. With a mid-sized Tokyo agency at JPY 4 million (about USD 26,700) plus maintenance at a market assumption of USD 400 a month, the total is about USD 26,700 + 14,400 = USD 41,100. With Kolonell Premium at USD 8,900, Japanese transcreation at about USD 5,000 and the same USD 400 market assumption after the 3 included months (33 months, USD 13,200), the total is about USD 27,100. Compliance review costs are similar in both cases and excluded.
Need a professional website?
Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
A local agency is the better choice when your audience is mainly Japanese retail users, when your marketing team works only in Japanese and needs in-person workshops, or when the site is tightly bound to a Japanese-built trading platform that the same vendor maintains. Kolonell fits better when your first readers are international partners, institutions and investors, and English is the working language of management.
Questions to ask any provider: who wrote sites for regulated firms before; how risk warnings are managed across pages; whether you can edit licence details without a developer; where the site is hosted and how personal data from forms is stored; what exactly is excluded from the price.
Mini case study
*Illustrative example, fictional firm.* Kanda Ledger, a registered digital asset firm in Tokyo serving corporate clients, compares two quotes. A Tokyo agency proposes JPY 4.5 million (about USD 30,000) for a Japanese and English site in 4 months. Kolonell proposes Premium at USD 8,900, with Japanese and English set in the quote, in 6 weeks. Kanda Ledger adds USD 5,500 for Japanese transcreation from its usual translator, so USD 8,900 + 5,500 = USD 14,400. The difference with the local quote is about USD 15,600, which the firm assigns to an external security review of its onboarding forms. The client portal remains a separate project, on quote.
FAQ
Can the site be in Japanese and English?
Yes, through the Premium tier at USD 8,900, the multilingual tier, with languages set in the quote. Japanese copy is produced by a third-party translator or your team, typically JPY 400k to 1.2M for a corporate site.
How long does a fintech website take?
Kolonell delivers Starter and Growth in 3 to 4 weeks and Premium in 4 to 6 weeks, once content is available. Compliance review on your side often adds 1 to 3 weeks.
Should we show our registration number on the homepage?
Many registered firms show it in the footer of every page and on a dedicated licences page, exactly as it appears in the official register. Your compliance officer should approve the wording.
Is the client portal included?
No, gated areas, onboarding flows and integrations with trading or custody systems are on quote. A separate scoping usually takes 1 to 2 weeks.
What happens after the 3 months of support?
Maintenance is on quote, depending on update frequency and hosting. Market assumptions in Tokyo range from about USD 150 to 600 a month.
