On the record
Checkpoint: New CEO Takeshi Sano reveals refreshed international strategy
The call
Dentsu's Japan business is healthy and growing, but its international arm is shrinking, unsold, and exposed to AI tools that do the same work for less.
Dentsu is an advertising agency that helps companies create ads and buy media time. Its Japan business is solid and growing, but its international operations (the companies it bought like Carat and Merkle) are under pressure because Google, Meta, and Amazon let advertisers buy ads directly without needing an agency middleman, and now artificial intelligence can write copy and pick audiences faster than humans could. The real test will be whether new CEO Takeshi Sano can stop the international side from shrinking or whether Dentsu ends up selling more pieces of itself, and whether its rumored partnership with OpenAI actually makes money or just speeds up the replacement of ad workers.
Why
01
AI pressure: OpenAI ChatGPT Ads plus generative tools from Google and Meta. Dentsu itself says AI cuts up to 95% of man-hours on ad work, the same work clients used to pay agency fees for. Could AI do the core job? Yes, likely.
02
Bigger players: Publicis Groupe and the merged Omnicom-IPG. Publicis grew 5.5% and Omnicom-IPG became the biggest holding company by revenue while Dentsu grew 0.3% and lost a buyer for its international unit. Could a giant copy it? Probably.
03
What protects it. Japan, about 40% of revenue, grew 6.2% and still pays the bills while international bleeds.
What would change this call
Dentsu reports Q1/Q2 FY2026 international organic growth figures. Shows whether international arm has stabilized or continues losing ground to rivals.
New CEO Takeshi Sano unveils refreshed strategy in early FY2026. Reveals whether Dentsu has a credible plan to stop international decline.
Dentsu announces further piecemeal divestitures beyond the ANZ Merkle sale. Would indicate continued retreat from international markets rather than stabilization.

Questions people ask
- Is Dentsu profitable in 2026?
- Dentsu posted a statutory net loss of ¥327.6 billion for FY2025 (as of Feb 13, 2026), driven by a ¥310.1 billion goodwill impairment on its international arm. For FY2026 it guided to a forecast net profit of ¥69.7 billion, but that has not yet been confirmed by results.
- Could AI replace Dentsu's ad agency work?
- Dentsu itself disclosed in May 2026 that AI can achieve up to a 95% reduction in man-hours for digital advertising tasks like copywriting and targeting, the exact billable work international agencies charge for, making core services highly automatable.
- Who is Dentsu's biggest competitor?
- Publicis Groupe outgrew Dentsu with 5.5% organic growth in 2025 versus Dentsu's 0.3%. Omnicom's completion of its IPG merger on Nov 26, 2025 created a rival with over $25 billion revenue and $75.6 billion in billings, larger than Dentsu.
- Did Dentsu sell its international business?
- No. Dentsu engaged Mitsubishi UFJ Morgan Stanley and Nomura in Sept 2025 to explore a sale of its international operations, but abandoned the full sale in Feb 2026 after buyer talks collapsed, while remaining open to smaller local divestitures like the May 2026 Merkle ANZ deal.

- Is Dentsu cutting jobs?
- Yes. Dentsu announced roughly 3,400 international job cuts in Aug 2025, about 8% of its overseas workforce, tied to a ¥52 billion restructuring plan. By Feb 2026, 2,100 had been executed with 1,300 more planned, while group headcount stood at 67,454 as of Dec 31, 2025.
