OECD Survey on Drivers of Trust in Public Institutions 2026 Results: Japan
Table of contents
The OECD Trust Survey explores people’s perceptions of different public institutions in their country and the degree to which they trust their government. These perceptions range from day-to-day interactions with public institutions to decision making on complex policy issues. It showcases evidence on people’s experiences with and expectations of government reliability, responsiveness, fairness, integrity and openness. The 2025 survey, which followed earlier rounds in 2021 and 2023, includes 33 OECD countries and 5 OECD accession countries. The survey covers a representative sample of the adult population of each participating country. It was carried out between 10 September and 20 October in Japan, aligned with data collection in a majority of participating countries.
Between 2021 and 2025, Japan recorded an increase in trust in the national government. High or moderately high trust rose considerably, from 24% in 2021 to 46% in 2025, above the OECD average (40%).
Share of population who indicate different levels of trust in their national government (on a 0-10 scale), 2025
Note: ‘High or moderately high’ corresponds to the aggregation of response options 6-10 to the question “On a scale of 0 to 10, where 0 is not at all and 10 is completely, how much do you trust the national/federal government?”; neutral to option 5 and “low or no” to response options 0-4.
Trust in public institutions in Japan varies across institutions, and tends to resemble the OECD averages for several political and administrative institutions. In 2025, trust was higher in law-and-order and administrative institutions than in political institutions, in line with OECD-wide patterns. 56% trust the police, 59% trust in the courts, while trust in political parties stands at 29%. 45% trust the civil service, similar to the OECD average.

Note: ‘High or moderately high’ corresponds to the aggregation of response options 6-10 to the question “On a scale of 0 to 10, where 0 is not at all and 10 is completely, how much do you trust [institution]?”. Country-specific terms may have been used in the survey implementation for some public institutions. The labels in the figure are used to facilitate cross-country comparison.
Findings from the OECD Trust Survey 2025 indicate that trust gaps are generally largest along political dimensions, especially partisanship and political agency, while gaps linked to socio-economic conditions (such as financial hardship, education, or perceived discrimination) are typically narrower, and differences by age and gender are usually the smallest. In Japan overall, the pattern of which characteristics matter most is in line with the OECD-wide pattern.
In terms of gap size, the divides in Japan are larger than the OECD average for political agency/voice (49 percentage points (p.p.), compared to an OECD gap of 47 p.p.); and for financial hardship (25 p.p. compared to OECD 18 p.p.). Trust gaps by education are pronounced but smaller than the average OECD education trust gap of 14 p.p: trust in the national government is 8 percentage points higher among people with a post-secondary degree (52%) than among those without an upper secondary education (44%). Age patterns differ from the OECD average: young people in Japan report more trust (52%) than those aged 50+ (48%). Among women in Japan, the share with high or moderately high trust in the national government is 6 percentage points smaller than among men (compared to OECD 7 p.p.).
Share of population with high or moderately high trust in the national government by population group, 2025
Note: ‘High or moderately high’ corresponds to the aggregation of response options 6-10 to the question “On a scale of 0 to 10, where 0 is not at all and 10 is completely, how much do you trust the national/federal government?”.
Perceptions of day-to-day dealings with public institutions in Japan are broadly in line with the OECD average, with Japan scoring above the OECD average on 6 out of 13 indicators. This provides a snapshot of how well people feel public services and frontline interactions work in practice (for example, how easy it is to access services, get information, and have issues resolved).
Across OECD countries, people who report more positive day-to-day experiences with government also tend to report higher trust in the national government, particularly those who are more satisfied with administrative services, feel benefit applications are treated fairly, and believe the public sector uses data legitimately.
In Japan, satisfaction with administrative services stood at 70% in 2025; perceived fairness in benefit applications increased from 40% (2021) to 56% (2025); and perceived legitimacy of public sector data use increased from 30% (2021) to 44% (2025). Overall, this indicates broad improvement in day-to-day experiences, which, in OECD-wide results, are meaningfully associated with trust.

Note: The figure presents the unweighted OECD averages and values for Japan of the share of respondents who choose a response of 6-10 on the 0-10 scale for the above questions. Satisfaction with public services is restricted to recent service users.
Overall, people in Japan rate decision making on complex policy issues above the OECD average on 1 out of 15 indicators, pointing to a less favourable public assessment of how well the governmental system handles complex, long-term issues, incorporates citizen input, weighs competing interests, and acts in the public interest.
At the OECD level, when it comes to more complex aspects of governance, trust is most strongly associated with positive perceptions that the government uses evidence in decision-making, that it can balance the interests of different generations, and that people like you have a say in what the government does.
In Japan, positive perceptions of the use of evidence stood at 41% in 2025; views on balancing intergenerational interests reached 28% in 2025; and political voice increased from 29% (2021) to 49% (2025). Taken together, this indicates mixed perceptions in aspects of complex decision-making that, at the OECD level, are strongly associated with trust.

Artificial intelligence (AI) is rapidly becoming embedded in the way governments design, deliver, and manage policies. Understanding how people expect governments to use AI, and the conditions under which they find that use acceptable, is therefore essential for shaping credible strategies and maintaining trust. For the first time, the 2025 OECD Trust Survey gathered evidence on familiarity with AI and public expectations about its potential benefits in government. In Japan, 23% say they understand AI “well enough to explain it to someone else” when asked to rate their familiarity with it.
When asked about future AI use in the public sector, 42% of Japanese people believe the government will use AI to provide more tailored services, while 49% think AI will be used to reduce costs. 33% are confident the government will protect personal information when using AI, 31% believe human oversight will be maintained, and 32% think the government will be transparent about how AI is used. Finally, 31% believe the government will ensure fair treatment when AI is deployed in public services. Overall, across the six dimensions, people in Japan are close to the OECD average about the potential use of AI by government agencies.
Levels of confidence in the potential of government AI use to fulfil the respective expectation, OECD, 2025
Note: The figure shows the OECD averages of responses to the question “Thinking about how government agencies could use AI in the future, how confident are you that government agencies will achieve the following outcomes?” “Confident” corresponds to a response of 6-10 on the 0-10 scale, “neutral” to 5 and “not confident” to 0-4 on the 0-10 scale. The OECD average is calculated as the unweighted average of weighted country averages.
