Key Trends and Drivers
Shift application security left through secure-by-design and SBOM adoption
- Japanese enterprises are moving application security earlier into software design, development, and procurement. This is visible in Japan’s policy direction around secure-by-design and software bill of materials (SBOM). METI and Japan’s National Cybersecurity Office jointly signed international SBOM guidance in September 2025, positioning SBOM as a way to improve software vulnerability management and supply-chain transparency. IPA has also continued to guide developers on vulnerability handling from the planning and design phase.
- Japan’s manufacturers, financial institutions, public agencies, and technology providers rely on packaged software, cloud components, open-source libraries, and third-party development partners. This creates exposure beyond internal code. The country’s policy focus is therefore shifting from only detecting vulnerabilities after release to making software component visibility part of development and procurement governance.
- SBOM, secure coding, software composition analysis, and vulnerability response workflows are expected to become part of vendor qualification, especially in regulated and critical sectors. Japanese buyers will likely expect application security vendors to support audit-ready reporting, software supply-chain visibility, and integration with developer pipelines rather than standalone scanning.
Treat APIs as core infrastructure, not only integration points
- API security is becoming a dedicated application security priority in Japan as companies connect mobile apps, payment systems, customer portals, cloud services, and partner platforms. APA Group adopted Akamai API Security in July 2025 after API usage expanded across hotel booking, check-in, guest services, and internal operations. CTC also signed a Japan reseller agreement with Cequence Security in January 2025 to provide API visibility, monitoring, and managed API security assessment services.
- Japanese businesses are using APIs to reduce development time and connect external services, but this increases the risk of shadow APIs, unauthorized access, data leakage, and attacks on customer-facing applications. This is especially relevant for finance, hospitality, telecom, public sector, retail, and e-commerce, where APIs carry customer identity, transaction, booking, and payment data.
- API discovery, API posture management, bot mitigation, and runtime protection will become part of mainstream application security programs. Demand will intensify as Japanese enterprises consolidate WAF, API security, DDoS protection, and bot controls into web application and API protection platforms.
Expand protection from WAF to WAAP as bot and DDoS activity affects digital channels
- Japanese companies are moving beyond traditional WAF rules toward broader web application and API protection. Casio adopted Akamai Bot Manager Premier and Content Protector in December 2025 to protect its global e-commerce site from bot traffic, scraping, and automated purchase activity. Hitachi Solutions and Radware also announced a cloud application protection service in November 2025 focused on application-layer and API-targeted DDoS attacks.
- Retail and consumer brands in Japan are becoming more dependent on digital storefronts, mobile apps, and online product launches. In this environment, bot traffic can affect availability, inventory fairness, customer experience, and revenue conversion. At the same time, Japan has seen application-layer attack concerns that affect transportation, logistics, commerce, and customer operations.
- WAAP adoption will increase among Japanese retailers, manufacturers with direct-to-consumer channels, travel companies, and financial institutions. Buyers will prioritize managed protection, AI-assisted detection, policy tuning, and incident support because internal teams may not be able to manually tune controls during high-volume attacks.
Align cloud application security with government cloud and data-residency expectations
- Cloud application security in Japan is being shaped by government cloud requirements, ISMAP expectations, and the need to protect applications hosted across domestic and global cloud platforms. Japan’s Digital Agency continues to track Government Cloud progress, including Sakura Internet’s cloud development plan, while Government Cloud requirements emphasize information security and safe data storage.
- Public-sector modernization, financial-sector digitization, AI infrastructure investment, and cloud migration are increasing the number of applications hosted in cloud environments. Microsoft also announced investment in Japan from 2026 to 2029 to expand AI infrastructure and strengthen cybersecurity cooperation, including work with domestic firms such as SoftBank and Sakura Internet.
- Application security in Japan will become more cloud-native and compliance-linked. Demand will grow for cloud workload protection, container security, cloud WAF, API security, secrets management, and developer security controls that can operate across hybrid environments. Vendors with Japan-based support, ISMAP alignment, local partner ecosystems, and cloud integration will have stronger positioning.
Competitive Landscape
Over the next 2-4 years, competition will intensify around API security, WAAP, SBOM-led vulnerability management, and cloud-native application protection. Large integrators are likely to bundle these controls into managed security offerings, while global vendors will rely on Japanese partners for enterprise access. Local vendors can gain share where buyers need a developer workflow fit, Japanese compliance alignment, and services around remediation.Current State of the Market
Japan’s application security market is becoming more competitive as demand moves from periodic vulnerability testing to continuous protection across web applications, APIs, cloud workloads, and software supply chains. Competition is shaped by three forces: large domestic system integrators serving regulated enterprises, global security vendors bringing WAAP/API security platforms, and local specialists addressing Japanese development teams. The government's focus on cybersecurity industry development and SBOM adoption is also pushing enterprises to evaluate application security as part of software governance, not only as a technical control.Key Players and New Entrants
Domestic players such as NTT DATA, IIJ, CTC, Hitachi Solutions, and GMO Flatt Security are important because Japanese buyers often prefer vendors with local delivery, Japanese-language support, and integration capability. IIJ’s Managed WAF Service, being registered under ISMAP, strengthens its position with public-sector and regulated customers. Global vendors such as Akamai, Radware, Cequence Security, and Apiiro are also gaining relevance through API security, WAF, bot protection, and application security posture management.Recent Launches, Mergers, and Acquisitions
Recent activity shows partnerships rather than large application-security M&A. CTC signed Japan’s first reseller agreement with Cequence Security in January 2025, expanding API security distribution. Hitachi Solutions launched Radware Cloud Application Protection Service in Japan in November 2025 for application-layer and DDoS protection. GMO Flatt Security formally released the DAST function for its AI security diagnosis agent “Takumi byGMO” in November 2025, showing local innovation around developer-facing testing.This report provides a detailed data-centric analysis of the application security industry in Japan, covering market opportunities and risks across a range of cybersecurity domains.
