As AI is used in more and more areas of society, it’s no longer enough for technology to simply “work correctly.” Is it unfairly discriminating against anyone? Can the basis for its decisions be explained? Is personal information protected? Answering these questions is a prerequisite for continuing to use AI safely and fairly. This page explains the concept of Responsible AI and its five core principles.
What Is Responsible AI?
Responsible AI is a collective term for the ideas and practices of developing, operating, and using AI technology with awareness of ethical and social responsibility.
Alongside pursuing technical performance (accuracy, speed), it aims to ensure “fair treatment for everyone,” “transparency in decision-making,” “protection of privacy,” and “accountability when problems occur.”
Why Responsible AI Matters
As AI’s influence grows, cases of unintended harm have been reported.
Real-world cases that became problems
| Case | Problem |
|---|---|
| Gender bias in hiring AI (Amazon, 2018) | A model trained on historical hiring data was reported to rate female applicants lower.[3] |
| Racial bias in facial recognition | The MIT Media Lab Gender Shades study found commercial gender-classification systems had error rates up to 34.7% for darker-skinned women.[4] |
| Bias in healthcare algorithms | A healthcare algorithm using cost as a proxy for need was reported to underestimate the medical needs of Black patients.[5] |
| Harmful speech from chatbots | Microsoft took Tay offline after malicious users induced inappropriate outputs within the first 24 hours.[6] |
These cases demonstrate that pursuing only technical accuracy is insufficient to prevent social harm.
Regulatory trends
AI regulations are being developed worldwide.
- EU AI Act (entered into force in 2024, phased application): Regulation that classifies AI by risk level. Prohibitions and AI literacy obligations applied from February 2025, and obligations for general-purpose AI (GPAI) models applied from August 2025; full application of high-risk AI obligations has been postponed to December 2027.[2][14]
- NIST AI RMF (2023): AI risk management framework from the National Institute of Standards and Technology.[1]
- G7 Hiroshima AI Process (2023): International guiding principles and a code of conduct for organizations developing advanced AI systems.[7]
Five Core Principles

A --> C["Transparency"]
A --> D["Explainability"]
A --> E["Privacy"]
A --> F["Accountability"]1. Fairness
Fairness means that AI does not unjustly discriminate based on attributes such as race, gender, age, or nationality.
Fairness has multiple definitions, and which one to adopt depends on the use case.
| Type of Fairness | Definition | Application Example |
|---|---|---|
| Individual fairness | Treat similar individuals similarly | Apply the same interest rate to people with the same credit score |
| Group fairness | Equalize error rates across different groups | Equalize pass rates between genders in hiring AI |
| Equal opportunity | Equalize probability of positive predictions across groups | Equalize loan approval rates across racial groups |
2. Transparency
Transparency means making the way an AI system operates understandable to users and supervisors.
- Disclosure that it’s AI (“This chat is powered by AI”)
- Providing information about the data and algorithms used in decision-making
- Clearly stating the model’s capabilities and limitations
Transparency is a prerequisite for people using AI to appropriately trust or question the system.
3. Explainability (XAI)
Explainability (XAI: eXplainable AI) means presenting the reasons behind an AI’s predictions or decisions in a form that humans can understand.
Example:
Transparency (bad example): "Your loan application has been denied."
Explainability (good example): "Your loan application has been denied. The main reasons are:
① Two late payments in the past three years, ② a high debt-to-income ratio,
③ and a short credit history."Fields where explainability is important: medical diagnosis support, credit assessment, hiring decisions, criminal justice
4. Privacy
Privacy means that AI handles personal data appropriately and protects it from unintended leaks or misuse.
- Data minimization: Collect and use only the minimum necessary data
- Purpose limitation: Do not use collected data for purposes other than what it was collected for
- Consent: Obtain explicit consent for the use of personal data
- Right to deletion: Respond to requests to delete personal data
Related regulations: EU GDPR (General Data Protection Regulation), Japan’s Act on the Protection of Personal Information.[8][9]
5. Accountability
Accountability means clearly defining responsibility for the behavior and impact of an AI system, and having the capacity to explain and correct issues when they arise.
- Defining the scope of responsibility for developers, operators, and users
- Establishing escalation processes when problems occur
- Mechanisms for challenging or appealing AI decisions
Types of AI Bias
AI bias refers to an AI’s tendency to systematically make incorrect judgments about specific groups or conditions.

B --> E["Imbalanced data collection\nReflection of historical bias"]
C --> F["Feature selection errors\nOptimization target errors"]
D --> G["Existing social discrimination\nreproduced and reinforced by AI"]Training Data Bias
Training data bias occurs when the data used to train the model is itself skewed.
- Lack of representation: Insufficient data for certain groups (e.g., insufficient data for minority ethnicities in medical AI)
- Reflection of historical bias: Learning from past discriminatory decision data reproduces those patterns
Concrete example: When hiring AI learns engineering role hiring data, if men were predominantly hired in the past, the model learns to favor men (the Amazon case).
Algorithmic Bias
Algorithmic bias occurs during the model’s design and optimization process.
- Feature problems: Using features that indirectly indicate race, gender, etc. (zip code, educational background, etc.) causes indirect discrimination
- Optimization target problems: Maximizing overall accuracy can sacrifice accuracy for minority groups
Amplification of Social Bias
Amplification of social bias occurs when AI learns social biases contained in training data and then reinforces and spreads them.
- Language model example: Learning patterns that associate “doctor” with “male” and “nurse” with “female”
- Image generation example: Generating predominantly white male images for the prompt “CEO”
Key Regulations and Guidelines
EU AI Act (Entered Into Force 2024, Phased Application)
The EU AI Act is a regulation that classifies AI by risk level and imposes obligations based on that level. Since entering into force in August 2024, its obligations have been rolled out in phases over several years.[2]

D --> D1["Chatbots\nImage generation AI"]
E --> E1["Spam filters\nGame AI"]The application schedule is phased. Prohibitions and AI literacy obligations applied from February 2025, and obligations for general-purpose AI (GPAI) models applied from August 2025. Under the “Digital Omnibus on AI” — politically agreed in May 2026 and entered into force on July 27, 2026 — full application of high-risk AI (Annex III) system obligations was postponed from the originally planned August 2, 2026 to December 2, 2027, and high-risk AI embedded in regulated products (Annex I) was postponed to August 2, 2028. As of August 2, 2026, transparency obligations (Article 50) — such as chatbot disclosure, labeling of AI-generated content, and deepfake labeling — newly apply.[14][15]
NIST AI Risk Management Framework
The NIST AI RMF is an AI risk management framework published by the National Institute of Standards and Technology (NIST) in 2023.[1]
Four core functions:
- GOVERN: Building organizational systems for AI risk management
- MAP: Identifying and classifying AI context and risks
- MEASURE: Analyzing and evaluating risks
- MANAGE: Prioritizing, responding to, and monitoring risks
Anthropic Constitutional AI
Constitutional AI is a safety technique published by Anthropic.[10]
- Defines a set of principles (Constitution) that AI should follow, and the model self-evaluates and improves based on those principles
- Core principles: “Helpful, Harmless, and Honest”
- The mechanism underlying Claude’s safety
Summary
- Responsible AI consists of five principles: fairness, transparency, explainability, privacy, and accountability
- AI bias arises from three sources: training data, algorithms, and social amplification
- The EU AI Act is risk-based regulation that ranges from prohibition to voluntary response depending on the application, and its obligations also apply on a phased schedule. As of August 2026, transparency obligations apply, while high-risk AI obligations have been postponed to December 2027
- It’s important to consider social fairness and safety from the design stage, not just technical accuracy

Frequently Asked Questions
Q: Is Responsible AI something only large companies need to think about?
A: No. It’s relevant to all organizations and individuals that use AI. Even small organizations — when using AI for hiring or deploying a customer support chatbot — need to consider bias, transparency, and privacy. The EU AI Act applies to all AI systems that affect EU citizens, regardless of company size.
Q: Can AI bias be completely eliminated?
A: Complete elimination is realistically difficult. Training data reflects society’s historical and cultural biases, and completely removing them is a challenging problem. Also, fairness has multiple definitions, and satisfying all of them simultaneously is sometimes mathematically impossible.[11] A realistic approach is to “identify and mitigate serious unfairness” and “continuously monitor to detect problems early.”
Q: Is there a trade-off between explainability and accuracy?
A: Generally, deep learning models are highly accurate but hard to explain (black boxes), while simpler models like decision trees are easier to explain but tend to have lower accuracy. However, explanation techniques like LIME and SHAP have been studied as ways to explain complex model predictions after the fact.[12][13]
Q: Does the EU AI Act apply to Japanese companies?
A: It can. The EU AI Act includes providers placing AI systems on the EU market or putting them into service in the EU, as well as providers and deployers of AI systems whose output is used in the EU.[2] The application date differs by obligation type: as of August 2026, transparency obligations (such as disclosing that content is AI-generated) apply, while high-risk AI obligations have been postponed to December 2027. Japanese companies serving EU markets should check whether their AI systems fall within its scope and which application date is relevant.[2][14]
