Why Hello World Japan Exists

Hello World Japan started from a simple frustration: building a life in Japan as an engineer is harder than it should be, and the information you need is often scattered, outdated, or written for someone who is not in your situation.

Some of that information is bureaucratic. Some of it is cultural. Some of it is just painfully practical: what kind of visa path makes sense, how to judge a company, what your rights are at work, what “good salary” actually means, and which parts of Japan's tech market are worth paying attention to.

Where this came from

I am Shih-Wen Su, originally from Taiwan. I first came to Japan in 2013, fell in love with the country quickly, and found my first engineering job here before I could even properly read hiragana and katakana.

That first chapter in Japan taught me a lot, including some very expensive lessons. I had a dream startup job, then ran into some of the worst work experiences of my life: broken trust, bad incentives, unclear protections, and the reality that as a foreign engineer, you can be very vulnerable when you do not fully understand the labor system around you.

I left Japan, came back in 2018, and spent the next several years working more deeply inside the local tech industry, eventually leading and mentoring both Japanese and foreign engineers. Over time, one pattern became obvious: many of the struggles foreign engineers face in Japan are surprisingly similar, even when the companies and job titles look very different.

That is the real reason this site exists. Not to sell a fantasy about moving to Japan, but to make the path clearer, fairer, and less lonely.

How the site changed

Hello World Japan originally started more like a community project for foreign IT talent. That spirit is still here, but the site has become more focused over time.

Today, the direction is simpler: straightforward Japan guides for engineers.

That means we prioritize practical content over vague inspiration. We write about:

  • Visas — engineer visas, HSP points, PR paths, and the real paperwork behind them
  • Work — hiring signals, job platforms, labor rules, career growth, and what companies actually care about
  • Money — remittances, taxes, salary realities, banking, and financial tradeoffs that shape daily life
  • Life in Japan — the systems, habits, and practical knowledge that make long-term life here easier

Who this is for

This site is mainly for engineers who are in one of these situations:

  • you want to move to Japan and need a more realistic picture of how the market works
  • you are already in Japan and trying to make better career, visa, or money decisions
  • you are technically strong but do not yet understand the local systems around work and life here

It is also for Japanese teammates, hiring managers, and community builders who want to understand what foreign engineers actually struggle with once they arrive.

What we believe

Japan can be a great place to build a career. But good outcomes do not happen automatically. People need better information, better expectations, and sometimes just a more honest explanation of how things work.

We try to write the kind of guides I wish existed when I first came here: concrete, calm, skeptical when needed, and written by someone who has already learned a few things the hard way.
