11-1. The Reality: “60–70% of Work Activities Are Technically Automatable”

According to recent analyses by McKinsey & Company, existing technologies—including generative AI—could technically automate activities that account for 60–70% of current work time.

This is not a distant vision, but a potential based on technologies that already exist today.However, many organizations are still far from realizing this potential.

Analyses in the same body of research suggest that the main reason for unrealized ROI is not the technology itself, but rather poor problem framing—specifically, where to start automation. High-volume, repetitive tasks such as data entry, ticket routing, and routine approvals are consistently identified as the most effective starting points.

For SMEs, the key is not to attempt full automation at once.Even automating around 30% of total operations, while reallocating the remaining 70% to human judgment, communication, and creativity, can deliver substantial impact.



11-2. Japan’s SMEs: AI Adoption Still at “1 in 6”

A 2025 survey by Rakuten Group of 300 Japanese SMEs found that only 16% are currently using AI, meaning five out of six companies have yet to adopt it.

The main barriers identified include:

  • Lack of technical expertise (34%)

  • Concerns about ROI (31%)

  • High implementation costs (28%)

Additionally, 40% of non-adopters stated they do not fully understand the benefits of AI.

This highlights that the biggest bottleneck is not technology itself, but rather an information gap and lack of concrete use-case understanding.

This aligns with findings from the G7 SME AI Adoption Blueprint, which emphasizes that SMEs struggle with:

  • Identifying use cases

  • Evaluating ROI

  • Scaling implementations



11-3. Start by Deciding “Which Tasks to Automate First”

Organizations that succeed in AI adoption share a common trait:they are deliberate about where to start automation.

Workflow-focused analyses suggest that employees often spend 20–40 hours per week on repetitive tasks, and automating these can yield ROI within 30–60 days in many cases (based on vendor case studies).

Typical starting points for SMEs include:

  • Back-office processes (data entry, invoicing, reconciliation)

  • Routine customer inquiries (hours, inventory, delivery status)

  • Sales follow-up emails and proposal drafting

  • Internal FAQs (HR, expenses, policies)

These tasks are:

  • High-frequency

  • Rule-based

  • Time-consuming

They are also well-suited to no-code AI agents and SaaS tools, making them ideal for achieving early wins.



11-4. Use “90-Day Payback” as a Practical Benchmark

Sana Labs recommends that successful AI projects should aim for:

  • Payback within 90 days

  • Weekly active usage above 60%

In some enterprise cases (vendor-reported), implementations have achieved:

  • 70% reduction in compliance reporting workload

  • Up to 34× ROI

  • 95% weekly active usage

While these are vendor case examples, the underlying principle is broadly applicable:

Evaluate AI investments by asking:

  • How much does the tool cost?

  • How many hours does it save per month?

  • What is the monetary value of those savings?

Using a 3-month payback horizon provides a practical and disciplined decision framework for SMEs.



11-5. Practical Criteria for Tool Selection (SME Perspective)

When selecting AI tools, SMEs should focus on:

1. Integration capabilityCan it easily connect with CRM, accounting, chat, and storage systems?

2. Security and data governanceDoes it comply with standards such as ISO 27001 or SOC 2?Where is the data stored?

3. No-code/low-code usabilityCan non-engineers operate and adjust workflows?

4. ROI and implementation speedCan it be deployed within weeks or months—not years?

The Rakuten survey reinforces that unclear ROI and cost transparency are major adoption barriers, making vendor accountability in these areas essential.



11-6. Governance and Policy: Defining the “Acceptable Line”

AI adoption raises concerns about regulation and reputation, especially for SMEs.

In Japan, government policy emphasizes:

  • Safety

  • Trustworthiness

  • Explainability

Guidelines from agencies such as the Japan Fair Trade Commission and METI outline key risk areas:

  • Privacy and security

  • Intellectual property

  • Misinformation (hallucinations)

  • Fairness and bias

For SMEs, the practical approach is not to navigate these issues alone, but to:

  • Follow industry guidelines

  • Leverage vendor compliance features

  • Seek expert advice when needed



11-7. Talent Shift: Developing “People Who Can Use AI”

The biggest constraint for SMEs is not technology readiness, but organizational readiness.

The G7 blueprint and studies by Access Partnership show that:

  • Only 33% of small organizations fully understand AI benefits

  • Compared to 74% in large enterprises

This indicates a shortage of people who can translate AI into business use cases.

A practical approach for SMEs includes:

  • Assigning one AI lead per department

  • Running small, continuous experiments

  • Sharing both successes and failures internally

Hands-on experimentation is often more effective than formal training programs.



11-8. Risk Management: Dependency, Black Boxes, and Data Leakage

AI-driven management introduces several risks:

  • Vendor lock-in

  • Black-box decision-making

  • Data leakage

To mitigate these risks:

  • Maintain human-in-the-loop approval for critical decisions

  • Always verify outputs against source data

  • Use tools with data protection features (e.g., zero data retention, on-prem options)

Japan’s policy direction strongly emphasizes “trustworthy AI”, making transparency and safety critical evaluation criteria alongside speed.



11-9. A Five-Step Roadmap for SMEs

A practical roadmap for SMEs can be structured as follows:

Step 1: Identify “time-draining tasks”List recurring tasks and evaluate frequency, clarity, and cost.

Step 2: Run small PoCsAutomate 1–2 processes and aim for ROI within 90 days.

Step 3: Build data and governance foundationsClarify data locations, access rules, and permissions.

Step 4: Expand cross-functional workflowsGradually automate end-to-end processes across departments.

Step 5: Transition to AI-first managementIncorporate AI assumptions into budgeting, hiring, and strategy.

The key catalyst is achieving one successful use case within three months.



11-10. A Message from Japan: “Cautious but Committed”

As demonstrated throughout this book, Japanese companies may not be the fastest adopters of AI, but they are steadily advancing with:

  • Strong execution capabilities

  • Careful, field-driven implementation

The combination of:

  • Labor shortages

  • High quality requirements

  • Complex business practices

is shaping a unique “AI Management OS” in Japan.

For global audiences, Japan represents a valuable testbed for AI-driven management.

Solutions that succeed here typically meet high standards in:

  • Accuracy and reliability

  • Regulatory compliance

  • Human-AI collaboration

For SMEs in Japan, the opportunity is not simply to import AI tools, but to build their own AI-driven operating models.

The “60–70% automation potential” does not imply the disappearance of human roles.Rather, it enables leaders and employees to choose what not to do—and focus on what truly matters.

That is the essence of AI-driven autonomous management.
