Digital Agency Japan (デジタル庁): What It Is and What It Controls
Japan's Digital Agency (デジタル庁), established 1 September 2021, leads government digital transformation and can direct other ministries' IT spending. What it controls, who leads it, and what it means for technology and cloud vendors.
Japan’s Digital Agency (デジタル庁) is the government body responsible for digital transformation across the state. It was established on 1 September 2021, reports directly to the Prime Minister rather than sitting under an existing ministry, and holds an unusual power for a Japanese agency: it can review and coordinate the IT budgets of other ministries.
That budget leverage is what makes it commercially significant. For a technology vendor, the Digital Agency is often the body that sets the standard even when a different ministry signs the contract.
Japan spent much of the 2010s quietly lagging its OECD peers on digital government, a gap that the pandemic made impossible to ignore. The Digital Agency (デジタル庁), launched in September 2021 under the Suga administration, was the policy answer. Four years on, it sits at the centre of Japan’s digital transformation agenda, holding unusually strong cross-ministerial convening power and a growing regulatory footprint.
For companies operating in Japan, the Digital Agency is no longer a novelty. It is a primary counterparty for any organization whose business touches public services, identity, data, cloud, cybersecurity, or platform regulation.
Mandate and legal basis
The Digital Agency was established by the Digital Agency Establishment Act (Digital-cho Setchi Ho, 2021), passed alongside the Act on the Formation of a Digital Society. The latter set out the policy vision; the former created the institutional machinery.
The agency reports directly to the Prime Minister and is headed by the Minister for Digital Transformation. Under the Takaichi cabinet, that role is held by Hisashi Matsumoto, who has signaled that cybersecurity and inclusive digital delivery are his top priorities. The current Digital Minister operates alongside a Vice-Minister for Digital and a digital-policy-focused Director-General.
The statutory mandate is wide. The agency is charged with planning and coordinating Japan’s national digital society strategy, leading the digitalization of government services, setting interoperability standards across ministries and local governments, overseeing the MyNumber identity system, and serving as a central authority on data policy and procurement.
Structure and reach
The Digital Agency is deliberately hybrid.
Roughly half of its staff are career civil servants seconded from other ministries, particularly the Ministry of Internal Affairs and Communications (MIC), METI, and MOF. The other half are private-sector specialists recruited on fixed-term contracts: software engineers, product managers, designers, and data scientists drawn from Japanese and international tech firms. This mix is unusual in Japanese government and has given the agency both its strengths and some of its public friction points.
The agency does not operate large line-ministry budgets in the traditional sense. Its influence comes from coordination authority, standard-setting, and procurement leadership. When the Digital Agency endorses a standard, chooses a cloud vendor, or designates a service-delivery approach, that choice typically propagates across the Japanese public sector.
Key policy priorities
Four programs define the Digital Agency’s current agenda.
The MyNumber system
MyNumber (マイナンバー) is Japan’s 12-digit personal identification number, issued to every resident. Originally launched for tax and social security purposes, MyNumber has become the backbone of Japan’s digital identity framework.
The Digital Agency is responsible for expanding the scope of MyNumber services, integrating it with the health insurance card, driver’s license, and passport systems, and resolving the data-quality and data-linkage issues that have dogged the system since launch. For companies in financial services, healthcare, insurance, and HR technology, how MyNumber evolves directly affects product design, onboarding flows, and KYC procedures.
Digitalization of government services
The agency is driving the migration of administrative processes online, from passport renewals and driver’s license updates to corporate tax filings and social security applications. The Government Cloud (Gov Cloud) program selects authorized cloud providers for central and local government workloads, a decision with major commercial consequences for global hyperscalers and domestic cloud vendors.
Cybersecurity and data governance
Cybersecurity policy is shared across the Cabinet Cybersecurity Center (NISC), the Digital Agency, MIC, and the Ministry of Defense, with the Digital Agency playing a particularly active role on government systems and critical service continuity. The agency also influences data policy through its work on cross-border data flows, the Act on the Protection of Personal Information (APPI) implementation for the public sector, and interoperability with allied digital partners.
Open data and GovTech
The Digital Agency has pushed the Japanese government toward machine-readable open data as a default, and has built a growing GovTech ecosystem by commissioning services from Japanese and international technology providers. Open data policy is particularly relevant for firms in logistics, mobility, construction, finance, and AI, where government datasets can be a commercial input.
How the Digital Agency interacts with other ministries
The agency’s cross-ministerial mandate requires close coordination with:
- MIC, which retains jurisdiction over telecommunications, broadcasting, and local government digital infrastructure
- METI, for digital industrial policy, platform regulation, and economic security
- MHLW, for MyNumber integration with health and pension systems
- Personal Information Protection Commission (PPC), for privacy rulemaking
- NISC, for national cybersecurity policy
- The Fair Trade Commission, for digital platform competition issues
Understanding which agency leads on which file is essential. Issues that look like digital questions often sit under the jurisdictional lead of another ministry, with the Digital Agency providing technical and coordination input.
Implications for companies operating in Japan
The Digital Agency is now a primary public affairs counterparty for any technology, platform, data, or digitally-enabled business operating in Japan.
Selling to the government: the certification path
For a technology vendor, the Digital Agency is less a policy counterparty than the body that controls the door to the public-sector market, and that door has specific, sequential gates. To bid at all, a supplier needs the government’s unified qualification (全省庁統一資格); to sell cloud or SaaS into government, it generally needs to be on the ISMAP register (the Information system Security Management and Assessment Program), the security-assessment list that is effectively a precondition for cloud procurement. The largest prize sits on the Government Cloud (ガバメントクラウド), the shared platform the Digital Agency runs and that central and local government are migrating onto. These are not abstractions: certification and standards positioning have become a prerequisite for commercial entry, and the standards applied to the Government Cloud propagate outward into almost everything procured against it.
We map the qualification and ISMAP gates in detail in our guide to selling to the Japanese government, and the platform itself in our overview of Japan’s shift to a domestic Government Cloud.
Regulatory design input
On digital regulation, the Digital Agency is an important voice even where it is not the lead regulator. Firms with views on AI governance, platform regulation, data portability, or cross-border data flows should engage the agency alongside METI, the PPC, and the Fair Trade Commission.
Identity-linked product design
Products that touch identity, KYC, onboarding, or public service integration should be designed around MyNumber’s current state and its likely trajectory. Getting this wrong creates rework later.
Talent and hiring
Because the agency itself hires senior private-sector talent on fixed terms, it is also a useful signal of the Japanese government’s thinking on digital priorities. Monitoring who joins and leaves the agency is a legitimate strand of market intelligence.
Challenges the agency still faces
Four years in, the Digital Agency is no longer a startup, but it is still maturing. Issues on the public record include data-quality problems in the MyNumber system, ongoing friction with local governments over digitalization, tension between private-sector and career civil service cultures, and the challenge of delivering coherent cross-ministerial outcomes in a system built for vertical ministry control.
None of this is fatal. It does mean that engagement strategies need to account for the agency’s real operating constraints, not an idealized version of its mandate.
Why this matters for public affairs in Japan
The Digital Agency sits at the intersection of public policy, technology, and economic security, and its decisions increasingly shape the commercial environment for firms well beyond the traditional tech sector. Organizations that treat the agency as a strategic counterparty, rather than a procurement desk, will be better placed as Japan’s digital regulation continues to evolve.

The scale underneath My Number
Japan publishes the annual volume of each administrative procedure. The figures for the My Number information-provision network give a sense of what the Digital Agency is actually operating:
| Procedure | Legal basis | Volume/year |
|---|---|---|
| Recording and management on the information-provision network | My Number Act Enforcement Reg. Art. 26(6) | ~216,900,000 |
| Notification in response to a data request | Art. 26(1) | ~216,900,000 |
| Identifier notification to enquiring agencies | Art. 27(1) and 27(5) | ~54,700,000 |
This is infrastructure rather than paperwork. Roughly 217 million inter-agency data exchanges a year run across that network, which is why the Digital Agency’s authority over other ministries’ IT budgets matters commercially: it is not coordinating a set of websites, it is operating the layer that the rest of digital government sits on. For a technology vendor, the standards applied to that layer propagate outward into everything procured against it.

Frequently asked questions
- What is Japan's Digital Agency?
- The Digital Agency (デジタル庁) is the Japanese government body responsible for digital transformation across the state. It was established on 1 September 2021 and reports directly to the Prime Minister rather than sitting inside an existing ministry. It runs the My Number identity system, the government cloud, and the standardisation of local government IT systems, and it sets the rules that most public-sector technology procurement now follows.
- When was Japan's Digital Agency established?
- 1 September 2021. Its creation was driven by the COVID-19 pandemic, which exposed how poorly Japan's government systems handled digital delivery. Benefit payments, contact tracing and case reporting all ran into fragmented systems that could not exchange data, and the political consensus that followed made a central digital authority possible after years of stalled attempts.
- What powers does the Digital Agency have over other ministries?
- More than a normal agency, which is the point of its design. It has authority to review and coordinate the IT budgets of other ministries and to issue recommendations on their systems, giving it leverage that a conventional bureau lacks. This budget-adjacent power is why it matters commercially: for large government technology programmes, the Digital Agency is frequently the body that sets the standard even when another ministry is the buyer.
- Who leads the Digital Agency?
- A Minister for Digital Transformation sits in Cabinet, supported by a Digital Monitoring Officer and senior staff. It is also notable for recruiting heavily from the private sector rather than relying solely on career officials, which makes its working culture and its receptiveness to vendor engagement different from a traditional ministry.
- What is My Number and why does the Digital Agency run it?
- My Number (マイナンバー) is Japan's national individual identification number system, paired with a physical and digital card used for tax, social security and increasingly health insurance. The Digital Agency inherited it as the foundation layer for digital government, because most other services depend on a working identity system. Its rollout has been politically contentious, particularly around linking the card to health insurance records, which makes it a live public affairs issue rather than a settled technical programme.
- How big is the My Number system in practice?
- Larger than most people assume. The information-provision network that lets agencies exchange My Number data handles roughly 217 million recording and management operations a year under the My Number Act enforcement regulations, with a further 55 million identifier notifications. Those volumes are why the Digital Agency treats identity as the foundation layer: almost every other digital government service depends on that exchange working.
