KubeCon + CloudNativeCon Japan 2025

Sustainable growth of open-source projects requires both technological advancement and collaborative growth within a diverse community. How to create a community with vendor diversity that can collectively drive technological progress is a hot topic of concern today. It is increasingly clear that establishing the right governance structure and technical roadmap is critical during a project’s evolution.

KubeEdge, the industry’s first cloud-native edge computing open-source project, has grown from its launch in 2018 to achieving CNCF graduation this year. Over the past few years, KubeEdge has worked alongside multi-partners to implement practical applications in various fields, including satellite and smart vehicles, while fostering the robust development of multiple SIGs.

In this session, we will discuss the KubeEdge graduation journey, focusing on technical roadmap, community governance, and project maintenance. We will explore how to unite a diverse array of vendors within the community to advance our technological initiatives. Additionally, we will highlight the latest developments of KubeEdge in the fields of AI and robotics, aligning with current trends. Join us to explore how to build a mature, diverse, and technologically leading open-source community.

Tokyo Gas reimagined its largest digital membership platform to accelerate innovation after market deregulation, moving from a lift-and-shift cloud approach, taking its first step towards a truly cloud native architecture.

In this talk, the myTOKYOGAS team shares how they adopted Kubernetes, Argo CD, and Istio to transition to microservices—achieving 4x faster deployments, 30% lower costs, and 30% less operational effort. With a small team, they launched their first microservice in just months, dramatically cutting down release times and building a scalable foundation for future growth. Learn how open source helped Tokyo Gas fuel agility and sustainability at scale.

8 year ago, we started to release Playstation products powered on top of Kubernetes. At the time, it was focused on accelerating our time to market. Little did we know that it would also provide the rallying flag for bringing together multiple parts of the organization to work in a consistent manner. With common features available to all application teams, they could focus on improving the game and game developer experience, instead of re-inventing toiling wheels.

As we look to the future, we're once again able to use the Kubernetes ecosystem as a rallying point. It's enabling us to expand our availability and capabilities into new hosting environments. We're moving up the value chain by replacing once novel but now bespoke components with modern and now commodity logic.

In this talk, we'll summarize our experience bringing a common platform to Sony Interactive Entertainment, what the future holds, and how the past, present and future help Playstation to continue to provide a gaming world where Play has no Limit.

“Wa” is a traditional way of behavior embedded in most of Japanese, meaning harmony, behaving for others etc. Under the spirit of “Wa”, Let’s see project maintainer, local community leader, enterprise developer and business strategist in Japan and hear their opinions to facilitate collaboration with global community and increase contributions from Japan.

This panel, featuring instructors from Kubernetes Upstream Training Japan, explores how this initiative has accelerated open-source involvement across the country since 2019. Our panelists will share personal stories, highlighting how the training lowers barriers, boosts motivation, and drives long-term community engagement. We’ll examine the current status of Japanese contributions to Kubernetes, discuss lessons learned from past participants, and propose strategies to strengthen future growth. Attendees can expect a candid conversation about nurturing collaboration, overcoming cultural and linguistic challenges, and fostering a thriving ecosystem. Whether you’re an aspiring contributor or a seasoned leader, join us to gain practical insights into cross-cultural community-building and discover the next chapter for cloud-native innovation in Japan.

Join us on an anime-powered journey to explore the power of eBPF in cloud native. Inspired by Sailor Moon and Dragon Ball GT, this talk breaks down how eBPF enhances observability, networking, and security, using the Sailor Guardians and Gohan to make eBPF approachable. We’ll break down topics like real-time observability by comparing it to psychic flames.
And just as unchecked power in anime can lead to chaos, eBPF’s immense capabilities need to be used wisely. Drawing from Dragon Ball GT's arc where the Dragon Balls become a threat, we’ll examine best practices for safe deployment of eBPF (e.g., LSM, verifier constraints, Linux Capability restrictions). Spoiler alert: our Sailor Guardians and Gohan will come out victorious, worry not!

By the end, you’ll gain a clear understanding of how to wield eBPF safely and effectively in cloud native environments, no Super Saiyan transformation required!

SBOMs (Software Bills of Material) are essential for improving visibility and security in the software supply chain. As open-source code drives modern development, organizations face growing security risks due to limited transparency in software dependencies. Attacks like SolarWinds (2020) and Kaseya (2021) highlight the urgent need for stronger software supply chain security.
However, SBOMs are often inaccurate. This talk explores why these inaccuracies occur, how attackers exploit them, and how to address these issues. A key challenge is dependency management file analysis (e.g., cargo.toml for Rust), which struggles to track components effectively.
Enter SBOMit, an OpenSSF sandbox project leveraging in-toto attestations to create cryptographically verifiable SBOMs. By capturing supply chain steps as they occur, SBOMit enhances accuracy, mitigates tampering risks, and strengthens security. This talk examines SBOMit’s role in improving SBOM reliability across the CNCF ecosystem.
