5-1. From Cost Center to Value Driver
For many Japanese companies, customer support has long been treated as a “cost center.” Call centers and inquiry desks are necessary, but the goal has traditionally been to minimize cost.However, research by Salesforce shows that 84% of customers consider the experience a company provides to be as important as its products and services. Customer support is no longer just an operational function—it directly shapes brand perception and customer loyalty.
At the same time, inquiry volumes are increasing while labor shortages are intensifying. According to McKinsey & Company, roughly two-thirds of customer service activities and up to 70% of customer interactions can be automated using AI. In Japan, the chatbot and AI assistant market is also expanding. DataM Intelligence estimates that Japan’s chatbot market reached approximately $414 million in 2024.
5-2. The Impact of AI on Customer Support: What the Data Shows
Global data indicates that AI-driven automation improves not only efficiency but also service quality.According to Cubeo, organizations adopting AI in customer support have achieved an average 61% increase in productivity and a 35% reduction in service costs.
AI chatbots can handle around 70–80% of routine inquiries, reducing call handling time by up to 45% and improving resolution speed by 44%.In addition, Convin.ai reports that AI-driven personalization can improve customer satisfaction (CSAT) by 12–27% and increase first contact resolution (FCR) by about 30%.
A case study by Ability.ai shows that response times can be reduced from over six hours to under four minutes, while CSAT increased from 89% to 99%.These results demonstrate that speed and consistency—core elements of customer experience—can increasingly be delivered by AI.
5-3. What Is Happening in Japan’s Customer Support Landscape
In Japan, AI is already beginning to reshape customer service operations.A study by GMO Research & AI found that 33.5% of business professionals were using generative AI in their work as of 2025. Common use cases include document creation (46.7%), idea generation (43.3%), and translation or writing support (46.7%), all of which are directly applicable to support knowledge bases and response templates.
However, adoption remains uneven. A survey by Rakuten Group shows that only 16% of SMEs in Japan have adopted AI, indicating a growing gap between large enterprises and smaller businesses.
At the same time, the market continues to grow, supported by government investment. Japan allocated approximately ¥196.9 billion to AI-related initiatives in its 2025 budget, accelerating adoption across industries, including customer service.
5-4. How Much Can Be Automated? — About 30% of Tasks Are Already AI-Friendly
A key question for many companies is how much of customer support can realistically be automated.Multiple analyses suggest that around 30% of contact center tasks can be automated using chatbots and generative AI.
Tasks well-suited for automation include:
FAQ-level inquiries (business hours, return policies, etc.)
Status checks (order tracking, account balance, reservations)
Simple updates (address changes, password resets)
In these areas, studies show that roughly 70–80% of routine inquiries can be resolved through self-service.
On the other hand, automation is more difficult for:
Complaint handling and refund negotiations
Cases requiring judgment or exceptions
Interactions involving nuanced Japanese language and cultural context
As a result, a hybrid model is emerging in Japan, where AI handles about 30% of tasks while human agents focus on more complex, high-value interactions.
5-5. The Value of AI Support Agents: Speed and Consistency
Autonomous AI support agents differ from traditional chatbots in that they can execute actions by integrating with systems such as CRM and inventory platforms.
In a case study by Ability.ai:
Response times improved from one business day to about 7 minutes
FCR increased from 35% to 55%
CSAT improved from 50% to 70%
Similarly, Convin.ai reports that companies implementing AI support agents achieved up to a 27% improvement in CSAT and up to a 40% reduction in call center costs.
In Japan, companies in industries such as aviation and e-commerce are beginning to adopt multimodal AI (text, voice, and image), combining real-time responses with sentiment analysis to improve both efficiency and customer experience.
5-6. How AI Is Transforming Human Roles in Customer Support
Rather than replacing jobs, AI is transforming them. By automating repetitive tasks, AI enables human agents to:
Focus on complex cases
Reduce stress from repetitive inquiries
Lower cognitive load through AI-assisted search, translation, and summarization
In Japan, AI is also being used for training purposes. Companies are introducing role-play tools powered by generative AI to simulate customer interactions, helping agents improve their communication and resilience.
Customer support roles are evolving from routine task execution to positions requiring judgment, empathy, and advanced problem-solving skills.
5-7. A Practical Approach for Japan: Step-by-Step Implementation
Japanese companies tend to adopt AI in a phased manner rather than jumping directly to full automation.
Typical steps include:
FAQ chatbot and knowledge search
Automating responses to basic inquiries
Supporting agents with knowledge retrieval
Agent assist (copilot systems)
Real-time suggestions during interactions
Automatic summaries and tagging
Limited-scope autonomous agents
Handling order tracking or reservation changes
Automating simple, rule-based processes
Governance and KPI monitoring
Tracking FCR, CSAT, response time, escalation rates
Continuously improving prompts and knowledge bases
This gradual approach aligns with Japan’s emphasis on quality, reliability, and customer experience.
5-8. Do Customers Really Accept AI Support?
Customer attitudes toward AI support are mixed.According to Cubeo, over 80% of customers report positive experiences with AI interactions.However, research by SurveyMonkey shows that around 79% of customers still prefer human interaction in support scenarios.
This apparent contradiction highlights a key insight:Customers do not prioritize whether support is delivered by AI or humans—they prioritize fast and accurate resolution.
In fact, case studies show that reducing resolution time (e.g., solving issues within minutes) has a greater impact on satisfaction than the type of interaction itself.
In Japan, a practical model is emerging:
Use AI for simple, quick tasks
Rely on humans for complex or sensitive issues
5-9. Bridge to the Next Chapter: Integration with Back Office Functions
While customer support automation is visible on the front end, it relies heavily on integration with back-office systems such as finance, billing, and inventory.
Refunds, invoice corrections, payment changes, and credit management all connect support interactions directly to financial outcomes.
The next chapter explores how AI is transforming back-office operations—particularly finance and accounting—and examines how organizations can balance automation with compliance and governance from a CFO perspective.
