Docomo is closing physical shops and pushing service to My docomo and phone lines exactly as price competition and past network-quality complaints make retention harder; an agentic frontline that resolves billing, plan and d POINT questions transactionally — co-engineered alongside NTT's own tsuzumi LLM rather than against it — turns the group's AI strategy into measurable frontline economics.
NTT Docomo is Japan's largest mobile carrier by subscribers, with the d POINT membership base among Japan's largest loyalty programs and d Payment among its top wallets.
Public factDocomo has been reducing the Docomo Shop physical network for years, shifting service load to My docomo, chat and phone — while an older subscriber segment still expects patient keigo voice service.
Public factNetwork-quality complaints in dense urban areas in 2023-24 were publicly acknowledged and drove churn pressure and remediation capex.
Public factParent NTT developed the tsuzumi lightweight Japanese LLM, commercially launched in 2024 — group policy will favor NTT AI assets somewhere in any conversational stack.
Public factahamo's online-only support model concentrates a digital-native segment whose entire service experience is chat — a natural first surface for full automation.
Reasoned inferenceRetention offers today are likely dialer- and shop-led with capacity limits, leaving most at-risk subscribers uncontacted before port-out.
Seller hypothesis — validateValidate with the account team before outreach: Where tsuzumi and NTT DATA assets are mandated in the conversational stack — and where gaps are acknowledged · Current retention-desk and dialer save rates, capacity and offer-matrix governance · Docomo Shop reduction roadmap and the volume actually shifting to remote channels · Incumbent contact-center vendors and any group BPO arrangements
Strong internal engineering — sell infrastructure, models, governance, or selected capabilities
Evidence: NTT group owns its own LLM (tsuzumi) and a massive engineering arm in NTT DATA, so a pure external platform sale is implausible; but tsuzumi is a lightweight model aimed at efficiency, not a full agentic voice frontline — the winning posture is co-building: NTT models and infrastructure where mandated, Gemini-class speech and the orchestration/communications layer where quality gaps are conceded.
Why they won't build the full stack: Even with group engineering, a production agentic frontline — telephony, barge-in voice, offer-matrix governance, evaluation at 100% coverage — is a multi-year build Docomo's competitive position cannot wait for; a co-build delivers measurable retention economics now while respecting group AI strategy.
NTT publicly launched the tsuzumi LLM commercially in 2024 and has made AI and data centers central to group strategy in investor materials.
GTM implication: Do not pitch against the group model — architect the proposal so tsuzumi has a declared place, and sell the agent platform, voice quality and communications layer around it.
Docomo's consumer ARPU remains under pressure from price competition and discount brands, keeping retention economics and cost-to-serve on the management agenda.
GTM implication: Lead with retention save-rate economics, the metric that most directly defends consumer revenue.
Docomo publicly committed remediation capex to network-quality complaints in dense urban areas during 2023-24.
GTM implication: Churn pressure from the quality episode makes proactive, well-governed retention outreach an easier internal sell now than in a stable year.
| Workflow | Why it matters here | Value | Complexity | Speed | Channels |
|---|---|---|---|---|---|
Churn-risk retention and win-back outreach 100% of the at-risk base contacted in-channel with matrix-bounded offers; save rate and offer economics attributed per conversation. | Every port-out to a discount brand compounds ARPU pressure; the at-risk base is far larger than outbound capacity can touch. Friction today: Dialer campaigns reach a fraction of at-risk subscribers in working hours; offers depend on which operator answers; ahamo users get email blasts. | VoiceApp chatSMSLINE | |||
Billing, plan and d POINT service desk One keigo-grade conversation resolves bill explanation, plan optimization and points questions with writes back to the systems of record. | Bill-shock, plan-change and points questions are the highest-volume contact classes across a 90-million-line base and the d POINT economy. Friction today: IVR trees route to queues; d POINT, billing and plan questions span systems a single human agent swivel-chairs through. | VoiceApp chatWeb | |||
Docomo Shop overflow and appointment desk Pre-visit triage resolves what needs no counter, books what does, and preps documents — shop capacity reserved for genuinely physical work. | A shrinking shop network concentrates demand on remaining stores; booked-out counters push frustrated customers to phone lines. Friction today: Shop visits require reservations; simple device and procedure questions consume counter slots that data migration cases need. | App chatVoiceWeb |
Voice & channel orchestration, telephony, conversational execution, session/state, routing, integration build. Capability coverage validated during implementation.
API access to these systems is the critical-path dependency.
Identity-bound sessions, policy-bounded actions, 100% audit logging, human approvals at defined points, in-tenant intelligence.
All figures are modelling estimates from the labeled inputs above — nothing here is customer-provided yet. The pilot's first job is replacing these assumptions with NTT Docomo's measured baseline. Package price covers implementation only; recurring usage billed separately.
Why this package for NTT Docomo: The estate spans consumer mobile, ahamo online-only support, d POINT/d Payment and Docomo Shop overflow — multiple business units and workflows from day one, which is Transform scope; a retention pilot seeds it.
Packages cover implementation and integration only. Recurring costs are billed separately: Tilicho Labs platform usage (~$0.15/call-min indicative, usage only), Google Cloud consumption, telephony/carrier charges, managed operations, and support & optimization. No package includes unlimited usage.
“The group has declared AI central to NTT's future; applying it to Docomo's own frontline — the largest consumer service operation in the group — is the most visible, measurable proof point that strategy can produce.”
“This is a co-build: tsuzumi and NTT assets where group policy wants them, Gemini-class multilingual voice quality and the communications layer where they win — one governed orchestration layer over BSS, d POINT and CRM instead of another monolith.”
“Shop closures moved workload to channels staffed for yesterday's volumes; elastic agentic capacity absorbs the shifted load without rebuilding the physical network's cost base in a call center.”
“Your retention capacity touches a fraction of the at-risk base and your shops are booked out; an agent that saves subscribers at 9pm and triages shop visits changes both curves at once.”
“APPI-aligned handling, offer-matrix enforcement, human gates on exceptions and 100% logged conversations — tighter conduct control than any dialer floor, with audit trails regulators can actually read.”
“Retention economics are directly measurable: save rate times ARPU against conversation cost, benchmarked against the dialer baseline in your own data — a consumption-priced pilot, not a platform bet.”

Customer-safe by construction: drafts are composed only from customer-facing fields. Account tier, build-vs-buy classification, priority score, internal routing, and partner-commercial detail are not inputs to the composer, so they cannot appear in a draft. Money figures are always framed as modelled from the customer's own volumes. Read before sending — you own what goes out.
Japan's largest mobile carrier runs one of the country's biggest service operations — tens of millions of subscribers, the d POINT economy, and a shrinking Docomo Shop network pushing ever more service to remote channels — inside an NTT group that owns its own LLM, making this a co-build at national scale.
Workshop with consumer CS and marketing leadership: quantify the uncontacted at-risk base and dialer save economics, then scope a retention pilot co-designed with NTT group AI stakeholders.
Entry: Churn-risk retention and win-back outreach · Transform package · 14–20 weeks phased across units. Human fallback throughout; success thresholds agreed before build.
