Marketing Agencies in Japan: A Buyer’s Guide for Overseas Brands

Search for a marketing agency in Japan and you mostly find lists of company names and the agencies’ own service pages. Neither tells you which kind of agency you need, how the industry works or what to settle before you sign.

This guide covers the four types of agency, how the industry works behind a proposal, how hiring runs, how agencies charge and six questions to ask first. If you already know the type you want and need company names, see our ranking of the best digital marketing agencies in Japan. If creators are part of your plan, our guide to influencer marketing in Japan gives the wider picture.

What a Marketing Agency in Japan Does

A marketing agency in Japan plans, produces and runs marketing for a client in the Japanese market. Depending on its type, it takes on some or all of five jobs: strategy, creative production, media buying, campaign operation and reporting. Establish first which of the five it owns and which it passes on.

The market is large enough to support many specialists. Dentsu’s annual study, published on 5 March 2026, put advertising expenditure in Japan at 8.0623 trillion yen in 2025, up 5.1%. Internet advertising reached 4.0459 trillion yen, or 50.2% of the total, the first time it passed half.

Why Overseas Brands Hire a Local Agency

Language. Ads, landing pages, creator briefs and negotiations with media owners and talent management firms all need native Japanese.

Japan-specific media. The channel mix differs from most Western markets. In the Ministry of Internal Affairs and Communications (MIC) FY2025 media survey of people aged 13 to 79, published in June 2026, LINE was used by 92.9%, YouTube by 81.5%, Instagram by 54.8% and X by 44.7%. LINE and the Yahoo! JAPAN portal are both run by LY Corporation, so a plan built only on the platforms you use at home can miss much of the audience. See our overview of social media in Japan and our social media usage survey.

Advertising rules. Japan has its own disclosure rules for sponsored content and strict limits on claims for cosmetics, health products and foods. A partner who checks copy against them every week lowers the risk of a pulled campaign.

What You Can and Cannot Outsource

You can outsource execution: creative production, ad operation, media buying, creator casting and reporting. You should keep the decisions that define your brand: positioning, pricing, final approval of what goes live, and ownership of your data, accounts and creative files.

Teams that start with “please handle everything” often find later that the accounts, tracking and creative files all sit with the agency. That is why ownership is the first of the six questions later in this guide.

Types of Marketing Agencies in Japan

Most agencies fit one of four types, though large groups often span several. Match the type to your goal, then use the last column to find names.

Full-Service Advertising Agencies

Full-service agencies are strongest where buying power matters: television, print, transit and outdoor, usually combined with digital. They can coordinate many suppliers on one launch. When a team also manages much larger accounts, a modest budget can get less senior attention. That is how capacity is allocated, not a flaw, but it is worth raising.

This type fits a major launch that includes TV or transit, or a budget large enough to buy several media at once. Before signing, ask which team will work on your account day to day and whether digital work is in-house or with a subsidiary. Names are in our list of top advertising agencies in Japan.

Digital and Performance Marketing Agencies

These agencies run search, social and display ads, SEO and affiliate marketing, and are judged on measurable outcomes such as cost per acquisition and return on ad spend. In Japan, the dividing line is whether they handle local platforms, especially Yahoo! JAPAN and LINE advertising, as well as Google and Meta.

Check two things: whether the agency writes Japanese ad copy and builds landing pages, and whether it creates ad accounts in your company’s name (the first of the six questions below). For names, see our ranking of digital marketing agencies in Japan. For channel strategy, see online marketing in Japan.

Social Media and Influencer Agencies

These agencies run brand accounts, cast creators, manage product seeding and collect user-generated content. In Japan, many established creators work through talent management companies or multi-channel networks that handle offers and approvals. A direct message from an overseas brand is often ignored or forwarded, so the agency’s existing relationships with those companies become the real selection criterion.

A PR firm is different: it is measured mainly by media coverage, while an influencer agency is measured by posts and their numbers. Our guide to influencer PR agencies explains the overlap. If creators are central to your plan, shortlist this type, and use our comparison of influencer marketing agencies in Japan to see who operates in the market.

Market-Entry Consultancies and Localization Partners

Market-entry consultancies help you decide whether and how to enter Japan: research, entry strategy, partner search and advice on setting up a local entity. Localization partners adapt your brand and materials for Japanese customers, which goes well beyond translation. Neither usually runs campaigns, so plan on pairing them with an execution agency.

This type fits best before you decide to enter or set up a company. If you hire one alongside an execution agency, agree who owns strategy and who owns delivery. Our guide to Japan marketing strategy compares entry models, and how to sell in Japan covers the commercial side.

How the Japanese Agency Industry Is Structured

Two features explain most of what you will see in quotes and team charts: media buying tied to commissions, and layers of subcontracting.

Media Buying, Commissions, and the Role of the Big Agencies

Japan’s largest agencies built their position on buying media space and time for clients. Pricing tied to media spend, where the agency earns a margin or commission on what you spend, is still common for TV and other mass media, often alongside separate planning and production fees. Rates vary by agency, media and contract, so read each quote on its own terms.

Even with internet advertising at half of Dentsu’s 2025 total, the other half, from television to newspapers and promotional media, is where mass reach is bought and where relationships with media owners count most. The practical point: if an agency earns more when you spend more on media, ask how it sets budget recommendations and when it would advise you to spend less.

Subcontracting Chains and Why They Matter to You

The agency you sign with is often the front desk, not the whole team. Production companies, ad operators, translators and casting firms may each take part of the work, and some subcontract again. This is normal in Japan and not a problem in itself.

It affects you in three ways. Each layer can add a margin. Revisions travel down the chain and back, so they take longer and can change meaning. And when something goes wrong, responsibility can be unclear. You only need to know who does the hands-on work for each part, which is the second question below.

How Hiring an Agency in Japan Works, Step by Step

From here, the guide turns from understanding agencies to hiring one. The process usually runs in six stages, and you have work in each.

Brief, RFP, and Shortlist

A request for proposal (RFP) makes proposals comparable. Include your objective, KPIs, a budget range, the period, the media in scope, who approves on your side and the language you need for meetings and reports.

The budget range matters most. Without it, one agency proposes TV and another a small social test, and the comparison tells you nothing. To build a longlist, start from the type you need, then check our ranking of digital marketing agencies in Japan and each agency’s site.

Proposals, Quotes, and the Approval Lag

Japanese agencies tend to ask many questions before proposing, and replies take time because decisions go through internal consensus and formal approval, often called ringi. A slow reply is not a sign of low interest. Answer clarifying questions quickly, because each open question holds the process up. For more on working norms, see our guide to Japanese business etiquette.

Contract, Kickoff, and Reporting Cadence

The contract should state the scope, deliverables, who owns accounts, data and creative, whether the agency may subcontract, termination terms and payment terms. At kickoff, agree meeting frequency, attendees and the language of reports, and fix the report template before launch so the right data is collected from day one.

Without a Japanese entity, the contracting party, invoice address and treatment of consumption tax can change, and Japan’s qualified invoice system, in place since 1 October 2023, adds its own requirements. Confirm the arrangement with a tax adviser.

How Agencies in Japan Charge

Agencies use four basic fee models, and many quotes combine two. The model matters more than the total, because it shows what the agency is paid for.

Commission, Retainer, Project, and Performance Fees

Match the model to the shape of the work. Ongoing operation, such as running ad accounts month after month, fits a retainer. A single launch fits a project fee. Heavy media buying tends to come with a commission, and performance fees work only when both sides trust the tracking.

Mixed models, such as a retainer plus a media commission, are common. Ask for each to appear as a separate line so you can compare agencies like for like. For influencer campaigns, our breakdown of influencer marketing costs in Japan shows reference costs and how quotes are built.

Line Items Quotes Tend to Leave Out

Translation and localization. If it is missing, ask who writes and checks the Japanese copy, and whether that is included.

Revision rounds. If the quote does not say, ask how many rounds are included and how extra rounds are charged.

Tools and measurement. If analytics and reporting tools are missing, ask whose name each tool contract will be in, because that decides who keeps the data.

For influencer work, add secondary usage rights: using creator content in ads usually needs separate permission and a separate fee. Our guide to influencer whitelisting in Japan explains how that works.

How to Choose: Six Questions to Ask a Japanese Agency

Put these six questions to every agency on your shortlist and ask for written answers.

Who will own the ad accounts, data, and creative?

If the agency creates ad accounts in its own name, you can lose the account history, audiences and optimization data when the contract ends. The standard approach is to create accounts in your company’s name and grant the agency access. The same applies to creative and tracking: who owns the videos, images and copy made for you, and whose name the analytics accounts are in. This is where what you keep, rather than outsource, becomes a contract clause.

Which work do you do in-house, and which do you subcontract?

This tests the subcontracting chain. You do not need every partner’s name, but you should know who handles strategy, copy, design, video, ad operation, creator casting and reporting. A good answer lists in-house and external work stage by stage and names someone inside the agency who checks external work.

Who on the team works in English, and who does the actual work?

The English-speaking account manager and the people producing the work are often different, and each hand-off is a chance for meaning to shift. Ask whether the working team joins regular meetings and whether you can review reports and creative in English. Also ask how a handover would work if your account manager changes roles or leaves.

What will the monthly report include?

Agree the metrics, detail, language and frequency before launch. If creators are involved, ask whether the report will show each creator’s audience country breakdown, since a Japanese-language account can still have many followers outside Japan. Also ask whether you can see the raw data in the ad platforms and analytics tools, not only the numbers the agency selects.

How do you handle Japan’s advertising rules?

Since 1 October 2023, stealth marketing has been a violation of Japan’s Act against Unjustifiable Premiums and Misleading Representations. The Consumer Affairs Agency regulates the business supplying the product, so disclosure is the advertiser’s responsibility even when an agency briefs the creator. Hiring an agency does not move that responsibility, so write into the contract who checks each post’s label. Our guide to Japan’s stealth marketing regulation covers the details.

Claims rules work differently. Article 66 of the Pharmaceuticals and Medical Devices Act bars false or exaggerated claims about medicines, quasi-drugs, cosmetics and medical devices by any person, so agencies and creators can be parties to a violation too. The Health Promotion Act also restricts exaggerated health claims for foods. Ask who reviews copy and captions, and how.

Can you show Japan results you are allowed to publish?

Confidentiality often stops agencies naming clients, so a lack of public cases is not a warning sign on its own. Ask what can be shared instead: industry, channels and campaign type. Ask separately about work for overseas brands, because an agency used only to domestic clients may be less familiar with English reporting and approvals from a head office abroad.

When You Do Not Need a Japanese Agency

You may not need an agency if someone on your team works fluently in Japanese and knows local media and advertising rules, because much of an agency’s value is language and coordination. The same applies if your global agency already runs LINE and Yahoo! JAPAN campaigns with native-speaking staff. And if your budget is small and you are still testing demand, an agency fee can take a large share of the spend. Start with our list of free influencer marketing tools in Japan and bring in a partner once you know what works.

FAQ

What does a marketing agency in Japan do?

A marketing agency in Japan plans, produces and runs marketing for clients in the Japanese market, covering some or all of strategy, creative production, media buying, campaign operation and reporting. Which jobs it owns depends on its type. The four main types are full-service advertising agencies, digital and performance agencies, social media and influencer agencies, and market-entry consultancies or localization partners. The types table in this guide shows what each one delivers.

What is the difference between an advertising agency and a digital marketing agency in Japan?

An advertising agency centers on media buying and mass campaigns such as TV, print and outdoor, while a digital marketing agency centers on running and measuring online ads, SEO and similar channels. The first is judged mainly on reach and awareness, the second on conversions and cost per acquisition. Large advertising groups often have digital divisions or subsidiaries, so look at what the team assigned to you actually does rather than the company’s label. The types table in this guide compares both.

How do I find a digital marketing agency in Japan that works in English?

Check English at two levels: the account manager and the people doing the work. An agency can have a fluent contact while its copywriters and ad operators work only in Japanese, so ask whether they join meetings and whether reports come in English. For a longlist, start with our ranking of digital marketing agencies in Japan. An English page on an agency’s website is only a starting signal, not proof of an English-speaking team.

How do marketing agencies in Japan charge?

Most use one or more of four models: a commission on media spend, a monthly retainer, a project fee or a performance fee. Retainers suit ongoing operation, project fees suit single launches, commissions come with heavy media buying and performance fees need reliable tracking. Ask for each model as a separate line so you can compare quotes fairly. For influencer campaigns, see our breakdown of influencer marketing costs in Japan.

How long does it take to start working with an agency in Japan?

It depends on the project, but time goes into predictable places. Agencies ask detailed questions before proposing, proposals and quotes pass through internal approval, often called ringi, and contracts go through legal review on both sides. The best way to shorten the process is a clear RFP that states your budget range and names your approvers, so agencies can propose once rather than several times. The step-by-step section maps each stage.

Do I need a Japanese entity to hire a marketing agency in Japan?

Not necessarily, but having one or not changes who signs the contract, where invoices go and how Japanese consumption tax and the qualified invoice system apply. Some agencies contract with overseas companies directly, while others prefer a local entity or partner. Confirm the arrangement with a tax adviser before signing. For the wider choice between setting up a company, working through a partner or selling cross-border, see our guide to Japan marketing strategy.

Should I hire an influencer marketing agency or a general marketing agency in Japan?

Decide by your main goal. If creators will drive your campaign, a specialist influencer agency usually fits better, because it works with talent management companies, checks PR disclosure on each post and can show each creator’s audience country breakdown. If you need integrated media buying or performance advertising across several channels, a full-service or digital agency fits better. Many brands use both, each with a clear scope. Our comparison of influencer marketing agencies in Japan shows who operates in the market.
