Hi — I’m @testkun.
This is the first post on the blog.

I’ve launched a blog called “Nannyakore” (“What even is this?”).
I wanted to put down why I started it, what kind of person I am, and what I’ll write about — all in one place up front.

Why a personal blog?

I’ve written on note, Zenn, and other platforms. They’re great, and I’ll keep using them.
But I got curious: it’s easier than ever to ship a blog with Astro, so I wanted to build my own.

While working on game hardware and side projects, I also wanted a place to keep code and learnings in article form.
Honestly, I wanted somewhere that isn’t tied to one platform where I can leave my output.

Who I am

🎮 Game developer ≈ generalist | design & art | programming
~8 years at game studios in Japan and abroad → freelance (a.k.a. “unemployed” in my head)
Now I focus on game hardware while poking at all kinds of creative work.

That’s the short version.

How I became a technical artist

I joined the industry as a designer, doing background art. I started scripting to work more efficiently — that’s how I got into programming.

I began writing shaders, studied lighting and rendering, and ended up as a technical artist — bridging artists and engineers.

Roughly, a technical artist is someone who:

Combines artistic sense with technical skills and handles pipelines, tools, optimization, and more.

It’s a role that doesn’t sit purely on design or engineering alone.

From Japan to overseas

After building experience as a TA at a major Japanese studio, I moved to an overseas studio because I wanted that experience abroad.

The job looked different from Japan: stronger programming expectations, and CI/CD and Git workflows were just part of the day. That stretch really widened my range.

Now

After a few years abroad, I wanted to build hardware, not only software, so I went freelance.

These days I design and develop game hardware, poke at indie dev and programming, investments, and more — self-styled NEET.

What I’ll write about

Curiosity-driven, so topics will wander. Broadly:

Tech

  • Game dev / technical art
  • Programming (Python, WebGL, Unreal Engine, etc.)
  • AI tools and indie projects
  • Hardware and electronics

Life & misc.

  • Art / design
  • Investing and money
  • Everyday observations and interesting finds

I won’t stick to one lane — I’ll dig into whatever catches my interest.

Too many topics?

Fair. But things connect in odd ways: game dev leads to hardware, hardware needs electronics basics, AI changes how you code… I want to capture those unexpected links.

What “Nannyakore” means

In daily life I often think “nannyakore” — “what even is this?” — when I learn something new, spot a surprising mechanism, or find something cool.

I chose the title to honor that feeling and dig in my own way.

Closing

Thanks for reading.
If you’re into technical art, game dev, programming, or indie projects, I hope something here helps.

Have a good one.
