Japan’s 2024 open-source picture is mixed: organizations reported growing business value and broad confidence in open-source security, yet fewer organizations contributed code and fewer had formal governance practices than the global comparison. Those findings come from 106 Japanese respondents to the Linux Foundation’s 2024 Japan Spotlight Insights Report: Open Source Trends, Challenges, and Opportunities in Japan, published in October 2024—not from a census of Japanese companies or a technical security audit.
What the 2024 Japan report measured
The report analyzes Japan responses to the Linux Foundation’s 2024 World of Open Source Survey, conducted from March through May 2024. Respondents had to be at least somewhat familiar with open source, identify a perspective they could represent, and provide employment information. The Japan sample contains 106 completed responses, with a reported margin of error of ±8.2 percentage points at a 90% confidence level.
Chart denominators vary. Some results exclude people who answered “Don’t know or not sure,” so percentages describe the respondents included in each question rather than every organization in Japan. The results should therefore be read as reported opinions and practices among survey participants.
Value is growing, but perceived importance trails the global result
| Measure | Japan | Global comparison |
|---|---|---|
| Respondents saying open source is valuable to their organization | 70% | 93% |
| Respondents reporting that business value from open-source use increased during the previous year | 76% | Not stated |
The distinction matters. Seventy percent said OSS was valuable, while 76% separately said the business value their organization derived from OSS had increased over the prior year. The second figure describes direction of change, not the share that considers OSS important overall.

In the report’s foreword, Linux Foundation Vice President of Japan Operations Noriaki Fukuyasu summarized the pattern as “More than two-thirds of survey respondents recognize OSS as valuable to their organizations, and three-quarters report increased business value from OSS this year.” That is a summary of survey responses, not an independently measured market statistic.
Security confidence exceeds formal governance
| Security-related response | Japan | Global comparison |
|---|---|---|
| Believe OSS is more secure than closed software | 72% | 86% |
| Report a formal OSS component-review process | 35% | Not stated |
| Have internal OSS manuals or checklists | 30% | Not stated |
| Require secure-development training | 20% | 24% |
These numbers measure beliefs and self-reported controls. They do not establish that open source is inherently safer. Security depends on how components are selected, maintained, configured, monitored and patched, as well as on the security of the surrounding product.
The gap between 72% security confidence and 35% reporting formal component review suggests that many organizations may rely on trust without a consistently documented process. A practical governance baseline would include an inventory of dependencies, ownership for each component, vulnerability monitoring, an update policy, license review and a documented exception path.
Japan’s technology priorities differ sharply from the global pattern
The survey asked, “Which technologies do you believe would benefit the most from being open source?” Japan respondents most often selected the following categories:

| Technology | Japan respondents | Global comparison |
|---|---|---|
| Artificial intelligence and machine learning | 28% | 46% |
| Augmented reality, virtual reality and 3D simulation | 24% | 4% |
| Cybersecurity | 24% | 28% |
The report connects Japan’s unusually high AR/VR and 3D-simulation interest with gaming, robotics and industrial simulation. That is the report’s interpretation of the response pattern, not a separate measurement of investment in those sectors.
AI/ML still ranked first in Japan, but its 28% mention rate was well below the 46% global figure. Cybersecurity was comparatively close to the global result. Because respondents could identify technologies they believed would benefit from openness, these percentages indicate perceived opportunity rather than adoption, spending or project performance.
Contribution is lower, and contributors describe practical friction
| Contribution measure | Japan | Global comparison |
|---|---|---|
| Organizations reporting that they contributed code to OSS projects | 27% | 42% |
Among Japanese respondents who contributed, 87% cited learning and personal development as a motivation. The main reported obstacles were:
- 49%: lack of time
- 47%: difficulty understanding contribution guidelines and processes
- 37%: communication barriers, including language differences
The pattern points to an enablement problem as much as a willingness problem. Organizations seeking more upstream participation can reserve contribution time, recognize it in performance planning, provide Japanese-language explanations where possible, pair newcomers with maintainers, and document the path from issue selection to review and release.
How contributors say their work is funded
For a question based on 59 Japan respondents and 114 total mentions, contributors identified several funding sources:
| Funding source | Share of mentions |
|---|---|
| Project-related service revenue | 34% |
| Employer funding | 32% |
| Government grants | 24% |
These options were not mutually exclusive: one respondent could name more than one source. The results therefore show a blended funding model rather than market share or the proportion of contributors supported by a single channel.

For technology leaders
Treat rising business value as a reason to measure OSS deliberately. Track where components reduce development time, improve interoperability or enable new products, and assign accountable owners for critical dependencies.
For security and compliance teams
Convert confidence into evidence. Maintain a software bill of materials, define review criteria, monitor advisories, set patch-service levels and train developers. The survey’s 20% training figure indicates that secure-development education is not yet universal among respondents.

Best Value
For engineering managers
Contribution targets should address the barriers respondents named. Protected time and clear contribution playbooks are more actionable than asking developers to volunteer after delivery work is complete.
For public agencies and ecosystem builders
Government grants were one of the reported funding sources, while communication and process clarity remained obstacles. Grant programs, shared maintainership and bilingual documentation could reduce the cost of participation for smaller teams and first-time contributors.
Limits you should keep in mind
- The sample has 106 Japanese respondents and a stated ±8.2-point margin of error at 90% confidence; it is not a census.
- Results are self-reported and may reflect the knowledge and perspective of people familiar with open source.
- Question-specific denominators change, especially when “Don’t know or not sure” responses are excluded.
- Security responses describe perceptions and reported practices, not vulnerability rates or independent audits.
- The report is a 2024 snapshot. The Linux Foundation announced a subsequent Japan report in December 2025, so this edition should not be presented as the latest available evidence about current conditions.
Bottom line for readers
Japan’s 2024 survey profile is neither an adoption failure nor a security verdict. Respondents reported that open source was creating more business value, and many trusted its security, but formal review, training and code contribution lagged the global comparison. The clearest opportunity is to turn interest—especially in AI, cybersecurity and AR/VR-related fields—into repeatable governance and well-supported upstream participation.
