Ambassadors

I contribute to Kubernetes SIG Docs as the Japanese localization owner within the CNCF community, and I am also an individual contributor to Kubernetes, Kubernetes CSI, and various Kubernetes SIGs. I serve as an organizer for study groups targeted at beginners, mainly covering cloud-native technologies centered around Kubernetes (https://k8s-novice-jp.connpass.com/). Additionally, I co-host broadcasts with friends on YouTube, where we share updates and news about cloud-native tools (https://www.youtube.com/@KubernetesInternal). When I give presentations, I often share findings from my research into the internal implementations of Kubernetes and its related repositories (https://speakerdeck.com/bells17).

He is passionate about cloud native technologies, especially Kubernetes, and is a professional in this field. He leads the localization of Kubernetes and CNCF documentation as a localization approver in SIG-Docs and a reviewer for several projects. Additionally, he is an active OSS contributor to Kubernetes and related projects. To encourage more people to join the community, he is part of the organizer team for Kubernetes Upstream Training.

Kensei Nakada is a software engineer, passionate about CloudNative tech. He’s a long-time Kubernetes contributor, mainly focusing on the scheduler as a SIG-Scheduling approver, and has led many major enhancements.

Kohei Ota is a Senior Field Engineer at Apple. He is a CNCF Ambassador and contributes to Kubernetes SIG Docs as the Japanese localization owner in the CNCF communities. He also organizes Docker Meetup Tokyo and CloudNative Days Tokyo; some of the biggest “container/cloud native” communities and conferences in Japan.

Why I am excited to be an ambassador: I’ve been involved with local cloud native community based in Japan. Unfortunately not many folks from Japan have tightened relationship with international community. I’m excited to be part of organizers of both sides and would love to help local experts become part of the international community!

For most of his 10+ year career, Nao has been involved in the architecture, design, and engineering of open source systems, including the Linux kernel, OpenStack, Kubernetes, and Hyperledger. Nao is currently working on cloud native and platform services. Nao had started the CNCF/Glossary Japanese translation projects and was one of the organizers of the Cloud Native Community Japan. https://community.cncf.io/cloud-native-community-japan/

Why I am excited to be an ambassador: As an ambassador, I look forward to energizing the technical/non-technical community in Japan and making connections with the global community.

Shu Muto is a Principal Software Engineer at NEC Solution Innovators, Ltd., a company within the NEC group.

He serves as one of the maintainers for Kubernetes Dashboard and holds the position of chair for SIG UI.

Since 2019, Shu has been organizing Kubernetes Upstream Training sessions in Japan, dedicated to training both contributors and mentors, and to promote the culture of open source.

• Kubernetes Upstream Training in Japan
• Kubernetes Upstream Training in remote

The following presentations were given in relation to Kubernetes Upstream Training:

• [KCSNA2019] How to Hold Upstream Training in Your Country and Get New Contributors! – Shu Muto, Kenichi Oomichi, Akihito Inoh
• [KCSNA2022] How Kubernetes upstream training has been held in Japan for four years, getting over the COVID-19 situation – Shu Muto, Xie Ziyi
• [KubeDay Japan 2024] Keynote: Empowering Japanese Contributors: Kubernetes Upstream Training – Shu Muto, Ziyi Xie

In addition, he serves as an organizer for the CNCF chapter in Japan, CNCF Cloud Native Community Japan, which was launched in November 2023.

He hopes to spread the culture of development within the open source community more than ever before and promote collaboration among developers around the world.

Toru contributes to OSS as an individual contributor. He is the author and lead developer of youki, an OCI Runtime in Rust, and I am also a maintainer of the OCI Runtime Specification. Additionally, he serves as a reviewer for runwasi and is involved in developing a world that utilizes containers and Wasm. Lately, he has developed an interest in Kubernetes schedulers. Furthermore, he has given presentations at KubeDay Japan and has spoken at various community events in Japan.

Why I am excited to be an ambassador: The area of container runtime is the unsung hero of the Cloud Native space, where the intricacies of the technology and new features often don’t get the spotlight they deserve. As a developer in this field, I want to help more people become aware of the exciting features it has to offer. I aim to encourage them to take the leap into this fascinating domain! I am also looking forward to assisting the Japanese Cloud Native community in becoming more vibrant on an international level.

Yoshiyuki Tabata is a Senior OSS Consultant at Hitachi, Ltd, responsible for API Security, especially Authentication/Authorization. As an authentication and authorization expert, he mainly consults on authentication and authorization infrastructure and API infrastructure, for example designing and building API/SSO systems in the financial, public, social, and industrial fields. He’s also a contributor to API-related OSSs such as Keycloak and 3scale and develops features based on feedback from actual projects he consulted. He’s also a conference speaker of API-related events and an author of some books and web articles about Identity and Access Management.

Why I am excited to be an ambassador: I usually consult with our customers on authentication and authorization infrastructure and API infrastructure (I have experience building systems for finance and government using Keycloak and Kubernetes), and it seems that the adoption rate of the CNCF family in general systems is still low in Japan. Also, in systems that adopt the CNCF family, there are many systems with weak security due to placing too much emphasis on developer experience and agility. Therefore, as a CNCF ambassador, I would like to use the knowledge I have cultivated through many projects (not only the knowledge as a security consultant but also the knowledge as a Keycloak contributor and a conference speaker) to disseminate solutions and know-how for a better and more secure CNCF ecosystem.
