Best Marketing Agencies in Tokyo (2026)

Introduction

These 11 agencies are the strongest full-funnel, performance and growth firms we could verify in Tokyo in 2026. They range from the advertising business of CyberAgent to smaller specialists in lifetime value and embedded digital teams, and each was chosen for its services, recent activity and published client or partner record.

Spending is moving their way. Dentsu’s annual survey estimated Japanese advertising at ¥8.1 trillion in 2025, with internet advertising up 10.8% to ¥4.0 trillion. Ownership has also tightened around the two largest groups: Dentsu Group holds about 52% of Septeni and 75% of Dentsu Digital, while Hakuhodo DY Holdings took a 51.15% stake in Digital Holdings, the parent of Opt, through a tender offer that settled in December 2025. AI agents for running campaigns and generating creative now feature in the published work of most firms here.

Every firm below has an active office in Greater Tokyo in 2026. The list is unranked, since the right choice depends on your channels, budget and how much of the work you plan to keep in-house.

The best marketing agencies in Tokyo

1. CyberAgent

Listed · Shibuya · cyberagent.co.jp

CyberAgent has sold internet advertising since 1998 and describes itself as one of the largest market share holders in Japan. Advertising makes up roughly half of group sales, alongside media, games and investment, and the company reports that the business grew 6.1% in its 2025 financial year. It works from Abema Towers in Shibuya.

The firm’s distinguishing feature is its investment in AI and production. AI Lab, founded in 2016, has about 100 researchers, and the Kiwami Prediction series generates video, banner, text and landing page creative. Kiwami AI Odaiba Studio adds LED walls and 4D volumetric capture. CyberAgent does not name many clients on its corporate pages, so ask for category-specific case studies.

2. Septeni

Listed, majority owned by Dentsu Group · Nishi-Shinjuku · septeni-holdings.co.jp

Septeni was founded in 1990 and about 90% of its revenue comes from internet advertising, much of it performance-based work aimed at conversions. Dentsu Group has held a majority since 2022, at about 52%, and Septeni also owns 25% of Dentsu Digital. In the first half of its 2026 financial year, revenue rose 9.5% to ¥16.7 billion.

Staffing and ICT companies together account for about 40% of revenue, and Septeni won Top Sales and Best Growth awards in Indeed’s partner programme for the second half of 2025. It can pitch alone or jointly with Dentsu. In September 2026 it agreed to make Mediahouse Holdings a consolidated subsidiary, having sold LION DIGITAL GLOBAL earlier in the year.

3. Opt

Hakuhodo DY group, through Digital Holdings · Chiyoda · opt.ne.jp

Opt is a digital marketing company focused on customer lifetime value, with services across in-house marketing support, data, advertising operations, LINE marketing and customer experience. Its parent, Digital Holdings, was the subject of a Hakuhodo DY tender offer in 2025, followed by steps to make it a wholly owned subsidiary. Opt also has offices in Osaka, Sendai and Okinawa.

Published case studies include Suntory Holdings, United Arrows, Orbis and Mitsui Fudosan. Recent recognition includes the Breakthrough Partner country award at the Amazon Ads Partner Awards 2026 and the Best LINE Mini App Award from LINE Yahoo. In June 2026 it reported building more than 100 task-specific AI agents on an internal platform called Skills Manager.

4. AnyMind Group

Listed · Roppongi · anymindgroup.com

AnyMind runs brand commerce and creator platforms from its head office in Roppongi Hills, with 17 offices across 13 markets. Listed in Tokyo since March 2023, it combines marketing with brand planning, production, e-commerce enablement and logistics, which makes it broader than a media-led agency. It bought MISM, a vertical video ad producer, and Bcode, a live streamer management company, in January 2026.

The group suits brands crossing borders in Asia. In September 2026 it reported supporting Korean skincare brand Dr.Reju-All on its online and offline expansion into Japan. Recent partnerships cover live commerce with Alibaba Cloud and Meta. Much of its published case work comes from other Asian markets, so ask for Japanese examples specifically.

5. Hakuhodo DY ONE

Hakuhodo DY group · Akasaka · hakuhodody-one.co.jp

Hakuhodo DY ONE describes itself as the digital core of the Hakuhodo DY Group. It was formed in April 2024 from the integration of two long-established digital firms, Digital Advertising Consortium and Irep, and had 3,290 employees in April 2026. Services span data technology, marketing communication and business transformation.

Its 2025 and 2026 honours include Agency of the Year at Meta’s Agency First Awards 2025, Performance Partner of the Year at Microsoft Advertising’s Agency Award 2025, and Pinterest’s PinPro Agency of the Year. In July 2026 it launched Agentic Commerce ONE with Hakuhodo, and in September it extended WISE Ads for programmatic TV to Yomiuri and Chukyo Television.

6. Dentsu Digital

Dentsu Group 75%, Septeni Holdings 25% · Shiodome · dentsudigital.co.jp

Dentsu Digital was founded in July 2016 and calls itself one of Japan’s largest integrated digital firms, with 2,596 employees at the end of 2025. It works from the Dentsu head office building in Shiodome, and its services run from consulting and digital advertising to commerce, loyalty, data, AI and cloud integration.

It won Agency of the Year at the TikTok for Business Japan Agency Awards 2026 and Meta’s Best Brand Award for 2025. Its creative record is also strong for a digital firm, with Cannes Lions 2025 Gold and Clio 2025 Grand Prix wins listed on its awards page. In October 2026 it launched an analysis service for AI search and, with Dentsu Inc., a purchase-based marketing offer.

7. Adways

Listed · Nishi-Shinjuku · adways.net

Adways is an internet advertising company founded in Osaka in 2001 and listed in Tokyo since 2006, now headquartered in Nishi-Shinjuku with 992 group staff at the end of 2025. Its agency business covers app and web marketing, and it builds its own advertising technology, including the UNICORN platform, the JANet network and the AMP series of agency tools.

App and game marketing is a natural fit. In September 2026 it expanded its support for game companies going overseas, and UNICORN announced a move towards AI agents handling ad transactions and operations. Adways also lists offices in Taiwan, the Philippines and the US. The corporate site does not name agency clients, so ask for references.

8. FreakOut

Listed holding company · Roppongi · fout.co.jp

FreakOut is an advertising technology group that develops and sells demand-side and data management platforms in Japan and overseas, with ad delivery consulting alongside. Its holding company sits in Roppongi, and the group includes UUUM and UUUM Marketing for influencer work, digital signage firms and the data company Intimate Merger.

In August 2026 it earned TikTok’s Agency badge, one of 13 certified agency partners in Japan, and it also offers HAWK, an AI agent for advertising operations. The company says HAWK cut operations workload by 87%. FreakOut is more technology-led than most firms here, which suits teams with in-house strategy that want delivery and operations support.

9. Supership

KDDI and Dentsu Group as shareholders · Toranomon · supership.jp

Supership describes itself as a data technology company, with a marketing solutions business built on data and ad delivery technology and a separate data solutions business. It lists KDDI and Dentsu Group as shareholders and had 361 employees in April 2026.

The firm’s work reaches into channels beyond standard media buying. KDDI Message Cast handles business messaging, and Supership Touch Gift distributes coupons with a touch of a smartphone to encourage in-store purchases, with a trial starting at two Lawson stores in October 2026. It fits briefs that connect telecoms data, messaging and retail.

10. Members

Listed · Harumi · members.co.jp

Members was founded in 1995 and had 3,005 employees at the end of September 2026. Its model is embedding digital staff alongside client teams, with the stated aim of helping those clients build in-house capability across marketing, data, service design and AI.

Published cases show the range. It supported in-house CRM and LINE segmentation at United Arrows, e-commerce organisation at Sunstar, customer experience work at KFC Japan and a content strategy for ANA Holdings. The model suits companies that want skills left behind when an engagement ends, and it needs a client team ready to take that work on.

11. Macbee Planet

Listed · Shibuya · macbee-planet.com

Macbee Planet was founded in 2015 and is listed on the Prime Market of the Tokyo Stock Exchange. It describes its business as LTV marketing, offering performance-based services across awareness, acquisition and retention, and had 201 employees in April 2026.

The firm is expanding through 2026. In October it announced a specialist team for global companies growing in Japan and said it would make JC&G a wholly owned subsidiary. Its site does not name many clients, so ask how performance fees are measured and which conversions count before signing.

What to look for in a Tokyo marketing agency

Start with group ties. Several firms here sit within or alongside Dentsu and Hakuhodo, which can give access to wider media, data and creative resources. Check how that affects independence in media recommendations, and whether competing accounts sit elsewhere in the same group.

Read platform awards as evidence of scale and certification in specific channels. Most large Tokyo firms publish long lists from Meta, Google, TikTok, LINE Yahoo and Amazon. They are useful for checking channel fit, particularly on LINE and TikTok. Ask who on your account holds the relevant experience.

Decide early how much you want to bring in-house. Septeni reported some large clients moving advertising operations in-house from 2025, and firms such as Opt and Members now sell support for that shift. AI agents are changing how operations are priced and staffed, so ask what is automated, what a person reviews, and how creative testing is reported. Overseas brands should also ask who will run the account in English.

Performance work creates a lot of small files: video cuts, banner sizes, copy variants and weekly reports, often across several channels. Check where those files live, how approvals are recorded and whether a client can find the current version of a creative without asking. That routine shapes how quickly a test reaches market.

How Fabric helps marketing agency teams

Fabric gives a marketing agency one workspace for files, client feedback and account knowledge, with AI search across all of it. The setup for performance marketing agencies keeps briefs, creative, reports and call notes together by client. Media buying, bidding and measurement stay in the ad platforms and analytics tools.

Creative variants can sit in Fabric’s cloud drive, which streams files on demand and takes no local disk space. Search works by meaning across documents, images, PDFs and transcribed recordings, and it reaches connected apps such as Google Drive, Notion and Gmail. A team looking for last spring’s retail campaign can find it without remembering a folder name. A Kanban board turns any folder into a pipeline whose cards are the files themselves.

Review runs through shared links. Share a file or folder with the client as a commenter, and no sign-up is needed. Commenters can leave timestamped comments on video and audio, draw on a video frame or an image and attach a comment, and highlight text in PDFs and documents. The team then marks each comment completed, so a round of feedback on ad cuts or banners works like a checklist.

For finished work, any file or folder can be published as a web page. Published links are view-only, with optional download, which suits monthly reports and final assets. Password protection covers any file or folder, and link analytics shows when each named recipient opened a link and how long they spent with it.

On Team plans, self-writing docs maintain a page for each client from meetings, Slack and the workspace, covering decisions, deliverables and open items. Fabric uses AES-256 encryption and holds CASA Tier 2, and customer data is not used to train AI models. Your own legal and technical teams should confirm what a given client contract requires.

Password protection and link analytics are included on Pro and Team plans, and self-writing docs on Team plans, which start from $125 a month. See plans for teams.

Frequently asked questions

What is the best marketing agency in Tokyo?

The answer depends on the brief. On 2025 and 2026 platform recognition, Hakuhodo DY ONE and Dentsu Digital have the longest award lists of the firms here. CyberAgent has one of the largest shares of Japanese internet advertising. Macbee Planet and Members suit narrower needs, namely performance-based LTV work and embedded teams.

What happened to Digital Holdings and Opt?

Hakuhodo DY Holdings launched a tender offer for Digital Holdings in September 2025 and held 51.15% when it settled in December. Digital Holdings then sought shareholder approval for a share consolidation to become a wholly owned subsidiary, with delisting scheduled for March 2026. Opt continues to trade under its own name and lists Hakuhodo DY Holdings as a major shareholder.

How are Dentsu Digital and Septeni related?

Both sit within Dentsu Group. Dentsu Group holds 75% of Dentsu Digital and about 52% of Septeni, and Septeni holds the remaining 25% of Dentsu Digital. Septeni is separately listed and can pitch alone or with Dentsu.

Which Tokyo agencies work with overseas brands entering Japan?

AnyMind Group supported the Korean skincare brand Dr.Reju-All on its Japanese expansion in 2026, and Macbee Planet set up a team for global companies growing in Japan that October. Septeni has reported growth from new global-brand clients. Ask each firm how much of the account team works in English.

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

The line is loose, since the largest groups do both. Firms on this list concentrate on digital channels, conversion, data and customer retention, while advertising agencies in Tokyo lead on campaigns and brand work across mass media.
