How to Choose a Vertical Video Ad Production Partner in Japan
Four Vendor Types, Engagement Models and Reading Quotes

Japan's vertical video ad market grew to „204.9 billion in 2025 (155.9% of the prior year) and is forecast to reach „564.8 billion by 2029 (CyberAgent, March 2026). As the market grows, so does the number of creatives you need. For overseas companies, finding a production partner who understands the nuances of Japanese can make or break results. This article walks through partner types, engagement models, what goes into a quote, the production process and what to watch when working from overseas, and closes with a list of questions to ask before you sign.

⚔ Key points

01šŸ“ˆ Why outsource vertical video for Japan

Start with market growth. According to Dentsu's "2025 Advertising Expenditures in Japan," internet advertising reached „4.0459 trillion of the „8.0623 trillion total, a 50.2% share and the first time it passed half. CyberAgent's survey puts Japan's vertical video ad market at „204.9 billion in 2025 (155.9% of the prior year), forecast to reach „277.1 billion in 2026 and „564.8 billion in 2029.

A growing market also means more ads competing in the same feed. Against that backdrop, overseas companies outsource vertical video for Japan for three main reasons.

Production partners come in many forms, though. What you get, and what you need to watch for, depends on who you hire. The following sections lay out the differences.

šŸ’” About the numbers in this article: Market size figures come from public surveys and listed-company disclosures. Guidance on how to run production and what to watch for comes from the du-o team's production and campaign experience; it is practical guidance, not statistics. Prices and timelines vary widely by company and project, so this article does not give price or turnaround ranges.

02šŸ¢ Four types of production partner

The partners you can hire for vertical video ads in Japan fall into four broad types. Rather than one being better than another, choose based on whether they fit your goals and setup.

TypeStrengthsWatch-outsBest fit
General production house (companies that make TV commercials and web video across the board)High quality in shooting, lighting and art direction. Strong at brand filmsBuilt around crafting each piece, so may not suit large numbers of variations or test volumes. May not have performance data from vertical adsWhen you want a flagship creative for brand awareness
Influencer / creator agencyCan cast creators with followings, so the post itself reaches people. Natural, conversational delivery comes easilyUsing content as ads (running it as paid media) often costs extra and needs a separate contract. Creators' freedom makes it harder to run tests with a controlled messageExpanding awareness, or building buzz from creators' posts
Ad agency with a production teamCan handle media buying, planning and production together. One point of contactIf production is subcontracted, you can end up far from the people making the work. The split between media fees and production costs can be hard to seeWhen you want to hand off both media and production together
Vertical-ad specialistFocused on short vertical ads and used to testing while producing at volume. Has set approaches for subtitles, openings and so onStrengths in genres and talent pools vary by company. Highly crafted brand films may not be their forteWhen your goal is acquisition and you want to keep creatives rotating

* Classification by the du-o team. In practice, many companies span more than one type.

If your goal is to swap creatives based on results, as with app installs or e-commerce purchases, prioritize a partner who can deliver volume and fast testing. If you want to convey a brand's world in a single piece, you will weigh quality more heavily. If you have both goals, splitting the flagship piece and the test volume between different partners is one option.

03šŸ“ Four engagement models

Contracts with production partners broadly take one of four forms. Price levels vary widely by company, so this section looks at the character of each model.

ModelWhat it isBest fitWatch-outs
One-off (per video)Each video is planned, quoted and produced separatelyWhen you want to test the fit first, or for a specific campaignEvery video means a new quote and review, so management effort grows with volume
PackageNumber of videos, lengths, revision rounds and so on are set and ordered togetherWhen you want several videos at once for testingCheck exactly what the package covers (resizes, number of subtitle languages, number of performers, etc.)
Monthly retainerA set number of videos or amount of work each month, produced on an ongoing basisWhen you want to run testing and improvement every monthCheck whether unused videos roll over, early termination terms and who will be on the team
Performance-basedPayment depends on results such as installs or acquisitionsWhen you want to keep upfront costs downDefine what counts as a result and how it is measured, who sees which data, and which side keeps the rights to the creatives

A sensible sequence is to start with a one-off or a package of a few videos, confirm the quality of communication and output, then move to a monthly retainer. Whatever the model, confirm in writing beforehand what is included and what costs extra.

04🧾 What a quote should include

If you compare only the total, it is easy to miss differences in scope. At a minimum, check that the following items are spelled out somewhere in the quote or contract.

ItemWhat to check
Planning and scriptingWho writes the script. Whether it includes rebuilding the message for Japan, or only translating your draft
Talent and usage rightsBeyond the appearance fee, the period, platforms and countries the footage can be used in. Terms for extending the period
ShootingNumber of shoot days, studio or location, scope of equipment and crew
Editing and subtitlesCut editing, on-screen text, number of subtitle languages, whether narration is included
Music and font licensingWhether background music, sound effects and fonts are licensed for paid advertising. Terms for using audio provided by platforms
Revision roundsHow many are included, and where extra charges start (major script changes, reshoots, etc.)
Copyright and secondary useWhich side owns the finished video. Whether it can be reused in other ads, on websites, in stores and so on
Variations and resizesWhether variations with a swapped opening, different lengths and non-9:16 exports (1:1 or 16:9) are included
Asset deliveryWhether you receive only the finished video, or also raw footage and project files
ReportingWhether a review of results and suggestions for the next round of production are included

The items most often overlooked are talent usage rights and music licensing. Even if everything is fine at the shoot, extending the run or using the ad in another country can require extra fees or replacements. Rights handling differs by country and contract, so check with a professional for important projects.

05šŸ”„ The production process and where delays come from

Producing vertical video ads generally follows this flow.

  1. Discovery: share the product, target audience, goals, past results and off-limits expressions
  2. Planning and scripting: decide on the opening type, message angle and structure, and write the script
  3. Script approval: finalize the shoot after internal and legal review
  4. Casting and pre-production: settle talent, location, props and shoot date
  5. Shoot
  6. Editing and subtitles: produce a first cut, get feedback and revise
  7. Final approval and delivery: deliver with export formats and sizes aligned
  8. Launch and review: look at results and feed them into the next script

In the du-o team's experience, most schedule slips come not from production itself but from waiting for script and first-cut approvals. Things tend to stall when too many people are reviewing, no one has been named as the final decision-maker, or another department (legal or brand) joins the review late.

šŸ’” How to avoid delays: Name one final decision-maker at the first meeting. Share off-limits expressions and required elements (logos, disclaimers, labels such as "åŗƒå‘Š" (ad) or "PR") before scripting starts. Consolidate feedback into one set instead of having each reviewer send comments separately.

Labels that show content is advertising (such as "åŗƒå‘Š" or "PR") have been subject to regulation under Japan's Act against Unjustifiable Premiums and Misleading Representations (the stealth marketing rules) since October 2023. For how to display them in specific cases, check the Consumer Affairs Agency's materials or consult a professional.

06šŸŒ Working with a Japanese production partner from overseas

When an overseas company works with a production partner in Japan, a few issues come up that don't arise in purely domestic deals.

Communication

Money and contracts

Many overseas brands have no track record in Japan yet. It helps to treat the first few videos as a period for testing how easy the working relationship is, not just the output.

07🚦 Red flags and good signs

By the meeting and quote stage, you can already see a fair amount about how a partner works. These are the signs the du-o team looks for.

Red flagsGood signs
The quote is a lump sum with no mention of talent usage rights or revision roundsScope is spelled out item by item, and conditions that trigger extra costs are explained
They promise results, such as "You will definitely see results"They explain concretely how testing will run and which metrics will guide decisions
They can't show past work, or only have horizontal videoThey can show vertical work along with its goals and genre
They ask to create the ad account in their own nameThey assume access will be granted to an account in your name
Asked about a script's intent, they only say "This is how it's done in Japan"They can explain in words why they chose a phrase or structure
Contacts change often and it's unclear who is overseeing productionThe point of contact and the person responsible for production are clear
They show no interest in checks around disclosure labels such as "åŗƒå‘Š" or "PR"Their proposals take platform review standards and disclosure rules into account

08ā“ Questions to ask before signing

Finally, here are questions you can use as-is when talking to candidate companies. Beyond the content of the answers, whether they come back quickly and concretely is itself useful information.

ā“ FAQ

Should I hire a Japanese production company, or have a production company in my own country make a Japanese version?
If you want results in Japan, we recommend involving creators who understand how Japanese viewers think. Script phrasing, how subtitles are broken up and how talent speaks are hard to fill in through translation. Even if you use a production company at home, bringing in Japanese creators for the Japanese script and talent selection reduces mismatches.
Which engagement model should I start with?
A sensible approach is to produce a few videos as a one-off or a package, confirm the output and how easy the working relationship is, then move to a monthly retainer. Whatever the model, confirm in writing beforehand what is included and what triggers extra charges.
What should I watch for when comparing quotes?
Compare like for like on scope, not just totals. The period and scope of talent usage rights, music and font licensing, revision rounds, resized and variation exports, and whether raw footage is delivered can change your real costs significantly.
How can I review a Japanese script from overseas?
Ask for the Japanese script to be translated back into English (back-translation), along with an explanation of why each phrase was chosen; that makes it easier to judge. At the editing stage, giving time-coded feedback with timestamps reduces confusion about where to make changes.
Can I let my production partner create the ad account?
We recommend creating ad accounts in your company's name and granting the partner access. If ads run from an account in the partner's name, you may be unable to take over campaign data and account history when the contract ends.
