Dentsu's refocus on Japan is an acknowledgement what the spending data already shows: geographic specialisation can now be more valuable than global scale.
For the past two years, I've written about the bifurcation of our industry. At one end, integrated giants: Publicis, Accenture (Deloitte on a smaller scale, and Omnicom if they execute the IPG merger flawlessly), building proprietary platforms and charging for managed services subscriptions. At the other end, specialists thriving on democratised AI tools: the creative boutique, the influencer shop, the experiential agency that does one thing superlatively.
And in the middle? The death zone. WPP with 114,000 employees but not enough integration. Dentsu outside Japan hemorrhaging $573 million in goodwill impairments this quarter alone. These agencies are large enough to carry massive overhead but not large enough to compete with giants or agile enough to match specialist quality.
The 22,000+ job losses across holding companies in 2024-2025 aren't distributed evenly, they're concentrated in this deathly middle.
Everyone understands this split now. Where the industry gets it wrong is how they define specialism.
The Specialisation Blind Spot
When we discuss specialists, we default to functional capabilities: the creative agency, the influencer shop, the retail media expert, the data consultancy. We think about the marketing value chain vertically.
But there's another axis of specialisation that 20 years of "the world is flat" made us forget: geography and culture.
From 2000-2020, geographic expertise became commoditised. Global platforms with standardised ad formats. Universal creative that "transcends culture." Centralised campaign management from global hub that gets "localised" by in-market.
But follow the growth. The three fastest-growing channels in marketing tell a different story than the "global scale wins" narrative:
1. Retail Media: $128 billion globally, $62 billion in US alone (2025)
Growing 20%+ while overall digital grows 7%. Some 85% of CPG brands now work with four or more retail media networks. In the US market, Amazon and Walmart absorb 84% of spend. Retail media success requires local infrastructure relationships that can't be scaled from global headquarters.
The winning agencies aren't those with the biggest global footprint. They're those with relationships with Carrefour in France, with local grocery chains in Southeast Asia, with regional retailers in MENA. They understand in-store activation logistics, local consumer behaviour, regional privacy regulations around retail data.
Europe's retail media market faces what analysts politely call "highly fragmented markets shaped by diverse consumer preferences" and "stricter privacy regulations." Translation: geographic and cultural expertise is the actual competitive advantage.
2. Influencer Marketing: $32.5 billion globally (2025)
Some 73% of brands prefer micro and mid-tier creators, who are inherently local. Asia-Pacific is recording the highest 35% growth rate, driven by "vernacular content" and "localised influencer marketing strategies."
Influencer marketing is local. The winning agency in Saudi Arabia isn't the one with a global influencer platform, it's the one that understands the rhythms of the Islamic calendar for campaign timing, knows which Saudi creators actually drive action versus vanity metrics, can navigate cultural and religious sensitivities that destroy campaigns when missed.
3. Experiential Marketing: $128 billion globally (2025)
Some 74% of Fortune 1000 companies are increasing budgets. B2C companies are spending $90.3 billion, B2B spending $38 billion.
You cannot run experiential marketing from a global hub. Pop-ups require local venue relationships, permitting, staffing, logistics. Brand activations at festivals demand understanding of local event culture. In-store retail media requires boots-on-the-ground coordination that global account teams pretend they can "manage remotely."
The data shows that "niche firms focusing on specific regions with more localised, personalised experiential marketing strategies" are winning business from global agencies. Because experiential is inherently, unavoidably local.
These three channels represent $288 billion in spending, growing 15-20% annually. And all three reward geographic specialisation over global scale.
Platform Disintermediation Favours Regional Specialists
Meta's Advantage+ and Google's Performance Max represent existential threats to the traditional agency model. These automated campaign tools are designed to eliminate the agency layer entirely.
Platform disintermediation is most advanced where platforms have the highest share of impressions.
The United States first. Meta and Google dominate American digital advertising. They have the scale, the data, the infrastructure to make "just upload creative and let us handle it" actually work.
But in markets where platform penetration is lower? Where local platforms compete? Where media is more fragmented? The agency still adds value that platforms can't replace.
In China, Baidu, Tencent, Alibaba, Douyin (TikTok), and Xiaohongshu each require distinct strategies. No single platform can claim "just give us your budget and trust our AI." Local agencies that understand the multi-platform ecosystem are thriving.
In Southeast Asia: Grab, Shopee, Lazada, local social platforms, plus global players. Fragmentation means complexity. Complexity means agency value.
In MENA: Different platform preferences by country (Snapchat in Saudi, Instagram in UAE), local publishers, regional media. The "upload and trust the algorithm" model doesn't work when algorithms aren't trained on your market.
The agencies most vulnerable to platform disintermediation are those dependent on US digital media, where platforms are strongest. Geographic specialists in markets with lower platform concentration have natural protection.
Then there's the factor that will force geographic specialisation whether agencies choose it or not: data sovereignty.
More than 100 countries now have data sovereignty laws. The GDPR requires EU customer data be stored in the EU. Russia, China, Germany, France, Indonesia, and Vietnam require in-country storage. Violations trigger fines of 4-6% of global revenue.
Currently, 92% of Western data sits in US-based infrastructure. This is creating a compliance crisis that global agencies structured around centralised data platforms cannot solve.
You need legal counsel who understands local data regulations. Engineers who can architect compliant infrastructure. Account teams who can explain to clients where their data actually lives and why it matters.
This isn't a "nice to have" cultural sensitivity training. This is: your agency could trigger multi-million dollar fines for your client if you get data storage wrong. And understanding data sovereignty requires deep local legal and technical expertise.
In-Housing Changes What Clients Need
Everyone sees clients bringing capabilities in-house and assumes this means "clients don't need agencies anymore." The opposite is true. In-housing is actually creating demand for best-of-breed geographic specialists.
What clients are in-housing: Strategy. Data. Centralised campaign planning. Platform management. The things that need to be close to the brand and integrated with business strategy.
What clients still need externally: Local market execution. Cultural expertise. Regional media relationships. On-the-ground activation. The last mile that corporate strategy doesn't do well.
The model emerging: Global brand strategy in-house plus best-of-breed regional execution partners.
A CPG brand doesn't need a "global agency of record" anymore. They have strategy in-house. What they need is the best retail media execution partner in each key market, the best local influencer agency in Southeast Asia, the best experiential activation partner in MENA, the best data sovereignty compliant infrastructure partner in the EU.
This is the opposite of "global AOR consolidation." This is clients selecting the actually best partner by geography and channel, not the one that promises "we can do everything everywhere."
For geographic specialists, this is opportunity. You no longer need to compete on "we have offices in 50 countries." You compete on "we're definitively the best at what we do in this region."
It's Not Just Japan
Back to Dentsu. Their fortress strategy, doubling down on Japan, potentially selling international operations, looks like retreat. It's actually the first major Western holding company recognition that geographic depth beats global breadth.
Japan: 5.3% growth with 29% margins. Ninth consecutive quarter of growth. International: $573 million in impairments this quarter, $1.4 billion last year. 3,400 layoffs. Stock down 43%.
But Dentsu isn't the first to understand this. They're just the first holding company willing to admit it publicly.
Look at China where I was based for 5 years. The largest Chinese advertising agencies likeBlueFocus, Hylink, JEBE United, Bluehalo Advertising, have built multi-billion dollar businesses by being definitively Chinese specialists. BlueFocus is worth over $3 billion. They didn't get there by promising "global reach." They got there by absolute dominance in understanding Chinese platforms, Chinese consumer behaviour, Chinese regulatory environment, Chinese cultural nuances.
When multinational brands enter China, they don't use their "global agency of record." They hire a Chinese specialist. Because trying to run Chinese marketing from London or New York is strategic malpractice.
The Chinese agencies proved the model: geographic specialisation at scale is not just defensible, it's more profitable than global mediocrity.
Platform fragmentation in China means agencies still add massive value. Cultural complexity means local expertise is mandatory. Data sovereignty requirements mean infrastructure must be local. Language barriers create natural moats.
And I'll make a prediction: Within five years, we'll see a MENA agency emerge at comparable scale.
The MENA region has all the ingredients. Market size growing from $8.18 billion to $10.78 billion (2025-2031). Platform fragmentation (different dominant platforms by country). Cultural and linguistic complexity that global agencies consistently mishandle. Data sovereignty requirements across different jurisdictions. Growing demand for local retail media, influencer, and experiential expertise. Wealthy markets (GCC) with significant marketing spend.
Right now, MENA is fragmented across multiple regional players and subsidiaries of global networks. But the agency that consolidates regional expertise, that becomes the definitive MENA specialist, will build a BlueFocus-scale business.
Not by promising global reach. By being so definitively expert in MENA that multinational brands and regional champions both choose them over global alternatives.
Japan proved it. China proved it at scale. MENA is next. And Southeast Asia after that.
For 20 years, the industry optimised for global scale. Standardised processes. Centralised planning. The growth channels made a different choice. Retail media, influencer, and experiential all reward local relationships and cultural depth. Data sovereignty regulations require it. Platform disintermediation is concentrated where global platforms dominate. In-housing clients want best-of-breed regional partners, not global compromise.
Geography is back on the map.
