Job Hunting in Japan as a Foreign PhD — Ten Rejections Before One Offer

If you found this article at 2 AM by searching something like “can’t find a job in Japan with a PhD” — this one is for you. Because that was me.

I applied to about ten companies. Every one of them rejected me.

Targeting My Own Field

I started logically. My doctorate was in nanophotonics and photothermal measurement, so I aimed at companies making optical measurement systems — spectroscopy, thermal measurement instruments. The places where my skills should have been an obvious fit.

I applied to a major measurement-instrument maker whose products I genuinely respected. Rejected. And so it went, again and again, at the companies closest to my own field.

That’s the part nobody warns you about: the rejections that hurt most aren’t from the stretch applications. They’re from the companies where you should have belonged.

Why a PhD Can Hurt

Here is the uncomfortable truth I learned: a PhD helps you get research jobs, and can actively hurt you everywhere else.

A doctorate signals deep, specific skills. When you apply outside that specialty, companies see someone overqualified in the wrong direction — expensive to hire, hard to place, and possibly a flight risk back to research. Meanwhile, my actual research — new measurement techniques using quantitative phase microscopy — wasn’t something industry needed yet.

It is honestly a sad feeling: holding a PhD while running away from research jobs. The degree I had sacrificed sleep and health for was, in this specific game, working against me.

The Sentence That Hit Hard

Someone at the university career center told me something I still think about:

A research institute and an industry have different objectives. For an industry to hire you, your research needs to match what the industry needs.

It hit hard because it was true, and because I heard it too late to act on it. Research institutes reward new discoveries. Industry rewards needed solutions. Those are not the same thing, and a PhD student who plans to leave academia should know which game they’re training for.

What I’d Tell My First-Year Self

If I could talk to myself at the start of the PhD, I’d say this: if there’s any chance you’ll leave academia, steer your research toward what people currently need — not only toward what’s newest. You can do excellent science on problems industry cares about. The job market will treat those two paths very differently.

I’m not saying my research was wasted — it made me who I am, and (spoiler for a later article) the publications ended up mattering in an unexpected way. But the mismatch cost me dearly in the job hunt.

Surviving the Interviews

People ask about my worst interview and my best interview. My honest answer: I don’t remember either. The whole period is a blur of the same routine.

That routine usually opens the same way: a self-introduction at the start of the interview, where you share what you did during your studies. It doesn’t have to be all research — you can include your hobbies or your club experience too, and for a PhD applicant that’s often a welcome signal that you’re more than your dissertation. (And for the record: nobody ever asked me why I was leaving academia.)

What I do remember is my survival tactic, and it was almost embarrassingly simple: answer every question positively. Whatever they asked, I framed it in the most positive way I could and kept moving.

Ten rejections in, that discipline was less about strategy and more about protecting my own morale.

Rejection number ten was not the end of the story. In the next article: how an agent changed everything, and the offer that arrived exactly one year before my graduation.
