Best Social Media Agencies in Tokyo (2026)

Introduction

Tokyo has a large and specialised social media agency market, and the 11 firms below cover its main types: SNS account operators, data-led consultancies, creator networks and agencies that help foreign brands reach Japanese audiences (or Japanese regions reach visitors from abroad).

Most of these firms sit outside Dentsu and Hakuhodo, and several pair agency work with their own software or influencer databases. The past two years brought new structures. FreakOut Holdings took UUUM fully private in February 2025 and UUUM spun out a dedicated marketing company that October, while PR group Vector set up Top Creators in September 2025 to focus on short-form video. Tribal Media House counts Hakuhodo DY ONE among its major shareholders.

Every firm here showed an active Tokyo office on a page checked in November 2026. The list was chosen for clarity of specialism, named client work and recent activity. It is unranked, and the numbers are for reference only, since the right choice depends on your brief, platforms and audience.

The best social media agencies in Tokyo

1. Comnico

Part of Lovable Marketing Group (listed) · Toranomon · comnico.jp

Comnico has specialised in SNS marketing since 2008 and employs about 140 people, with its head office in Toranomon, a Kansai office and a social media management centre in Kochi. Its group company, Lovable Marketing Group, listed on what is now the Tokyo Stock Exchange Growth market in December 2021. The firm also builds its own tools, comnico Marketing Suite and the campaign tool ATELU.

Case studies include support for Capcom’s official Biohazard account, Instagram operation for Mori Building and X consulting for Mitsubishi Pencil. Its service list runs from strategy and outsourced account operation to risk management, which suits brands wanting one partner for the whole account.

2. Hottolink

Listed (Tokyo Stock Exchange Growth) · Fujimi, Chiyoda · hottolink.co.jp

Hottolink is a data-driven marketing firm focused on earned media, with consulting built on social big data and a team of data scientists. It offers SNS consulting and account operation, with separate X and Instagram practices, alongside performance advertising, influencer work and the Instagram analytics tool hashpick.

Its published results centre on X. Case studies report review counts rising about eightfold in a year for confectioner Chateraise and about ninefold for Johnsonville Japan, plus a 140% increase in X mentions for an Alinamin Pharmaceutical product. Brands that sell through word of mouth and want UGC tracked with numbers should find this a good fit.

3. Gaiax

Listed company · Hirakawacho, Chiyoda · gaiax-socialmedialab.jp

Gaiax describes itself as a startup studio with social media as one of its focus areas, and its Social Media Lab is the agency-facing arm. The Lab handles account operation, creative production and filming, posting campaigns, influencer PR, SNS advertising and training.

Two services stand out: short drama production, and response planning for online flaming incidents. A joint IP case study with TV Tokyo appeared in Marketing LEADERS 100 in June 2026. The wider group spans education, DAOs and startup support, so ask which team will run your account.

4. Tribal Media House

Private, with Hakuhodo DY ONE among major shareholders · Shimbashi · tribalmedia.co.jp

Founded in 2007 and led by Noriyuki Ikeda, Tribal Media House covers social media operation, promotions, creative production and marketing training. It says it has supported more than 300 companies, around 75% of them national clients, and it lists fandom marketing among its specialities.

Client logos on its site include Suntory, Mazda, Japan Airlines, Sanrio and Duolingo. Recent case studies cover young-audience work for an Avex Pictures film and a VTuber music video for SS Pharmaceutical’s Allegion. In October 2026 it signed a strategic partnership with esports team operator REJECT.

5. Cyber Buzz

Listed (stock code 7069) · Sakuragaokacho, Shibuya · cyberbuzz.co.jp

Founded in 2006, Cyber Buzz runs a broad set of social services: the NINARY influencer network, the ripre product sampling service, the bridge account consulting service and the owgi operations tool. It also operates its own vertical media, including the TikTok-focused to buy.

Clients named on its company page lean towards beauty and health: Kao, Shiseido Japan, Kanebo Cosmetics, Orbis, Mandom and Rohto Pharmaceutical. MYPE, its media brand run with Kodansha’s ViVi, won the Partnership Award at the Kodansha Media Award 2026, and to buy and MYPE reached a combined 1.4 billion views that September.

6. LIDDELL

Private · Akasaka · liddell.tokyo

LIDDELL has worked in SNS and influencer marketing for about 12 years and reports more than 7,000 client companies and around 35,000 affiliated influencers. Its INFLUFECT platform handles influencer campaigns and social operations, and COMMUDA covers fan community strategy and management.

Logos on its site include Toyota, Shiseido, Sony, Uniqlo and KDDI, though it publishes few campaign details, so ask for relevant case studies. It expanded into AI during 2026, adding marketing team training and AI agent services. NHK interviewed its leadership about “smartphone farms” in July, which makes it a useful firm to ask about engagement fraud.

7. UUUM

Owned by FreakOut Holdings · Roppongi · uuum.co.jp

UUUM was founded in 2013 and built its name on YouTube creators. FreakOut Holdings made it a consolidated subsidiary in 2023 and then wholly owned, with the shares delisted in February 2025. Brand work has sat in a separate company, UUUM Marketing, since October 2025.

The firm reports more than 30,000 cumulative influencer projects and contact with about 48,000 influencers. Its services extend to casting, SNS ads, cross-border promotion and account management. Its creative studio Ichigeki Club, which blends live action and AI, won a Bronze at the ACC Awards in October 2026.

8. BitStar

Private · Shibuya · bitstar.tokyo

BitStar was founded in 2014, is led by CEO Taku Watanabe and has 162 staff, with a Kansai branch in Osaka alongside its Shibuya head office. Its work spans influencer marketing, social and ad operations, short video, talent management and a database of about 3 million accounts.

Client interviews on its site include Ajinomoto, Wacoal and Hankyu Hanshin Holdings, and it has published a TikTok case study for furniture retailer Nitori. The creator side is growing: October 2026 brought the game-creator label REC EDGE and BitStar Music. Brands wanting creators and production under one roof should look here.

9. Top Creators

Subsidiary of Vector · Akasaka · vectorinc.co.jp

Top Creators was established in September 2025 under PR group Vector and focuses on short-form vertical video. It works with creators who have hundreds of thousands to millions of followers, covering strategy, concept, production and distribution, and it operates Connect Tokyo Gourmet, a food media account with about 400,000 followers.

It is the youngest firm here and publishes no client names, so request references. Food, restaurant and retail brands have the most obvious fit, and the Vector link may help where social needs to sit alongside PR.

10. Tokyo Creative

Run by Redhorse Corporation · Yokoami, Sumida · tokyocreative.jp

Tokyo Creative is an influencer-led agency that promotes Japan to audiences abroad. It manages about 30 influencers with more than 13 million combined subscribers, and it runs a travel site in three languages with over 6,000 articles.

Clients are largely local governments and tourism bodies. Its case studies include Niigata City, Nishi-Izu Town and JETRO Ibaraki, working with English-language creators such as The Anime Man and Abroad in Japan. Most are undated, so ask for recent examples.

11. JapanBuzz

Run by FIT&Company · Shibuya · japanbuzz.info

JapanBuzz is a bilingual influencer and social media agency that has helped brands in Japan since 2012, with a Tokyo office in Cerulean Tower and a presence in London. Campaigns run across TikTok, Instagram, YouTube, note and X, with localisation, digital PR and market research alongside.

It suits overseas brands entering Japan and agencies that need a local partner. Its eight published case studies cover sectors from beauty to B2B SaaS, but client names are masked, so ask to see the full versions.

What to look for in a Tokyo social media agency

Start with the platform mix. Japanese agency service lists commonly treat X, LINE and note as core channels alongside Instagram, TikTok and YouTube, and a plan copied from another market may underweight them. Ask for results on the channels your audience uses, because a firm strong on X word of mouth may not lead on short video.

Decide whether you need account operation or creator reach. Firms such as Comnico and Hottolink centre on running and measuring brand accounts, while UUUM, BitStar and Top Creators start from creators. Many offer both, so look at which side their case studies come from.

Ask how disclosure and risk are handled. Japan’s stealth marketing rules took effect in October 2023 under the Act against Unjustifiable Premiums and Misleading Representations, and they apply to the advertiser, so undisclosed creator posts are the brand’s exposure. Check how an agency handles disclosure and flaming incidents, and take the final view with your own legal team.

Finally, look at the volume of review. An always-on account produces a steady flow of captions, vertical cuts and creator drafts, often with translation rounds when a global team is involved. Agree where the latest version lives, who approves it and how comments are tracked before the first posting calendar goes out.

How Fabric helps social media agency teams

Fabric gives a social team one workspace for its files, client feedback and account knowledge, with AI search across all of it. The setup for social content agencies suits firms running many accounts at once, with briefs, assets and reports kept together for each client.

Raw footage and creator files sit in Fabric’s cloud drive, which streams files on demand so they take no local disk space, and shared team folders hold the latest versions. Search works by meaning across documents, images and transcribed recordings, and colour search helps find assets by shade. Transcription makes uploaded video and YouTube URLs searchable, with results that jump to the timestamp, which helps when a team needs one line from a long creator interview.

Content pipelines fit Kanban, which turns a folder into a board whose cards are the files themselves. For client feedback, share a file or folder with the client as a commenter; shared links work without sign-up. Annotations then let the client leave timestamped comments on a video, draw on a frame or an image, and comment on captions in a document. The team marks each comment completed, so a round of changes works like a checklist.

Once work is approved, any file or folder can be published as a web page, such as a monthly report or a creator lookbook. Published links are view-only, with optional download, so feedback stays on the shared link.

On Team plans, self-writing docs can maintain a page for each client from meetings, Slack and the workspace, covering decisions, deliverables and open items. Team plans start from $125 a month. See plans for teams.

Frequently asked questions

What is the best social media agency in Tokyo?

There is no single answer, as it depends on the job. Comnico and Hottolink have detailed published case studies for brand accounts, UUUM reports more than 30,000 influencer projects, and JapanBuzz is built for overseas brands entering Japan.

What happened to UUUM?

UUUM is now a wholly owned subsidiary of FreakOut Holdings. FreakOut’s tender offer closed in September 2023, the shares were delisted from the Tokyo Stock Exchange Growth market in February 2025, and UUUM Marketing was set up as a separate company in October 2025.

Which Tokyo agencies suit a foreign brand entering Japan?

JapanBuzz is set up for this, with a bilingual team and market entry case studies. UUUM offers inbound and outbound support, including overseas influencer casting. Tokyo Creative works in the other direction, promoting Japan to audiences abroad, so it fits tourism and inbound briefs best.

Should I hire a social media agency or a wider marketing agency?

A specialist usually makes sense when social is the main channel or the account needs daily attention. If social is one part of a campaign with search, paid media and CRM, a full-funnel firm may be simpler, and our list of marketing agencies in Tokyo covers those.

Who is responsible for disclosing paid influencer posts in Japan?

Japan’s stealth marketing rules apply to the advertiser that supplies the product or service, and the influencer is outside the rule. Agencies can build disclosure into their process, but the brand should take its own legal advice on each campaign.
