The verdict in three sentences
For a private jet charter company in Tokyo, a dated site costs enquiries: an executive assistant or family office choosing between two providers first checks whether the operator or broker status is clear, whether cited audits are real and whether the English is flawless. A redesign with a Tokyo agency is often quoted at JPY 3 to 8 million (about USD 20,000 to 53,000), against USD 4,900 for Growth and USD 8,900 for Premium with Kolonell, the multilingual tier with languages set in the quote. The main risk is losing traffic during migration: it is managed with a URL inventory, a 301 redirect map and monitoring in Search Console.
The signals that hurt your credibility today
Business aviation clients departing Haneda or Narita are few and very demanding. They judge within seconds.
| Signal on the current site | What the client concludes | Expected fix |
|---|---|---|
| Unclear operator or broker status | "Who actually flies?" | A page stating the exact role and, for a broker, the certified operators used |
| Audit logos without detail | Doubt about safety | Cite ARGUS or Wyvern only if actually held, with its scope |
| Fleet shown in stock photos | Aircraft may not exist | Pages by aircraft category, real photos or a clear caption |
| Machine-translated English | Not credible internationally | Native English copy, Japanese reviewed by a native speaker |
| 15-field quote form | Time wasted, excessive data | Short form: route, date, passengers, contact |
| No empty legs page | Frequent query left unanswered | Dedicated, updated page, no invented fares |
In Japan, an operator must hold an air operator certificate issued by the civil aviation authorities; a broker should say so and never imply it operates the aircraft. This is not legal advice: have these pages reviewed by your counsel.
Budget: Tokyo agencies, freelancers or a fixed grid
2026 ballpark ranges from typical local agency quotes, converted approximately (USD 1 ≈ JPY 150).
| Option | 2026 ballpark (JPY) | Approx. equivalent (USD) | Note |
|---|---|---|---|
| Tokyo freelancer | 1,000,000 to 3,000,000 | 6,700 to 20,000 | Often strong in one language only |
| Local web agency | 3,000,000 to 8,000,000 | 20,000 to 53,000 | Project management in Japanese, English sometimes outsourced |
| Large or brand agency | 8,000,000 to 20,000,000 | 53,000 to 133,000 | Branding, video, campaign |
| Kolonell Growth | fixed price | 4,900 | In-depth content, qualified enquiry forms |
| Kolonell Premium | fixed price | 8,900 | Multilingual tier, Japanese and English set in the quote |
Included with Kolonell: a project manager reachable in your time zone, native English or French copywriting, delivery in 3 to 4 weeks (4 to 6 for Premium) and 3 months of support. Starter at USD 2,900 rarely suits a redesign at this level. Client areas, connected quote engines and integrations are on quote. See the international offer.
Timeline and redesign risks
Timings start once content is ready: approved copy, photos, the list of partner operators, audits actually held.
| Phase | Indicative duration | Risk | Mitigation |
|---|---|---|---|
| Inventory and scoping | Week 1 | Forgetting pages that generate enquiries | Export every URL with its traffic |
| Design and copywriting | Weeks 1 to 3 | Imprecise regulated content | Review of operator or broker role before launch |
| Content migration | Weeks 2 to 4 | Lost pages, duplicates | Page-by-page 301 redirect map |
| Launch | Week 3 to 4 (Premium 4 to 6) | Downtime | Switch-over outside peak hours, fallback site |
| Monitoring | 3 months included | Ranking drop | Search Console, 404 errors fixed weekly |
On data, Japan's Act on the Protection of Personal Information (APPI), overseen by the PPC, requires you to state how data is used and to frame transfers abroad. A charter form collects passenger names and sometimes passport numbers: only request the latter at booking, through a secure channel.
When a local agency is the better choice
A Tokyo agency wins if your clientele is mostly Japanese and you want in-person meetings in Japanese, full brand identity work and a campaign around a business aviation show. It can also handle local press relations.

Mini case study
Illustrative example: Kanto Skyline Aviation, a fictional charter broker, receives a local agency quote of JPY 6,000,000, about USD 40,000. Its site has 140 URLs: the inventory keeps 95, redirects 38 and removes 7 with no traffic (95 + 38 + 7 = 140).
It chooses Kolonell Premium at USD 8,900, with Japanese and English set in the quote. Difference: 40,000 − 8,900 = USD 31,100. It spends USD 4,000 on a real photo shoot at the business aviation terminal and USD 1,500 on a legal review of the page describing its broker status.
FAQ
How much does a private jet charter website redesign cost in Tokyo?
With a local agency, roughly JPY 3 to 8 million, or USD 20,000 to 53,000 (2026 ballpark). With Kolonell, USD 4,900 on Growth or USD 8,900 on multilingual Premium.
Will we lose our search rankings during the redesign?
A temporary dip is possible, but a full URL inventory and 301 redirects keep it limited. Monitoring is included during the 3 months of support.
Can we show indicative charter prices?
Only if they are real and dated, with their conditions. A price you cannot honour damages credibility more than no price at all.
Should we cite our safety audits?
Yes, if they are actually held, with the audit name and scope. Citing an audit you do not hold creates legal and commercial risk.
How long does the project take?
Allow 3 to 4 weeks on Growth and 4 to 6 weeks on Premium once content is ready, followed by 3 months of support.
Let's scope your project. A multilingual redesign on Premium at USD 8,900, languages set in the quote, or Growth at USD 4,900, with a full migration plan and delivery in 3 to 6 weeks. See the international offer or request a free quote: detailed reply within 48 hours.
