At KubeCon + CloudNativeCon North America 2025, I received the Kubernetes Contributor Award 2025 from SIG Cluster Lifecycle. The citation read: “being always available to help and for the impact he made in the Cluster API project.” I was genuinely happy, but it was also a good moment to look back on what I have actually done. So I want to write down the work that led to this award and what I learned along the way.

On February 21, 2026, Go Conference mini in Sendai 2026 was held. I gave a talk titled “Who tests the Tests?” and also enjoyed the other sessions and the after-party as an attendee. It was a great experience, so I want to write down my thoughts on the overall atmosphere of the event, my own presentation, and the community interactions in Sendai.

Sendai.go and Me

Sendai.go holds a special place in my heart. It was the very first offline conference I ever attended in person – Go Conference mini 2022 Autumn IN SENDAI. I had been speaking at Go Conference since I was a student, but back then COVID was only just beginning to settle down, so all my talks had been online. Speaking offline added a sense of liveness that’s hard to feel through a screen – seeing people actually listening, reacting in real time. I remember how much fun that was.
