What Do You Need to Teach English in Japan?

Imagine this: You're standing in front of 30 Japanese kids who are staring at you like you just landed from another planet. One of them raises her hand and asks, very seriously, "Teacher, are you real?"


Welcome to teaching English in Japan.

It's funny, chaotic and honestly, it's one of the most rewarding things you can do with your life. But before you pack your bags and start practicing how to say arigato, there's a practical question you need to answer first:

Do you actually qualify to teach English in Japan?

Spoiler: You probably do. But let's make sure — and make sure you're ready to walk in prepared, not surprised.

Why would you teach in Japan?

Let's be honest. There are plenty of countries where you can teach English. So why do thousands of people choose Japan every year?

Because Japan isn't just a job, it's an experience. Cherry blossoms in the spring. Ramen at midnight. Bullet trains that are more punctual than your alarm clock. A culture so rich and layered that you'll still be discovering new things five years in.

Oh, and the demand for English teachers? It's huge. Japan ranked 53rd in the world for English proficiency in 2020. The government knows it, the schools know it, and they're actively looking for people like you to help fix it. That means thousands of teaching positions open up every single year — in big cities, small towns, public schools, private language institutes, universities, and more. The opportunity is real. Now let's talk about what you need to grab it.


The 7 Things You Need to Teach English in Japan

1. A University Degree (In Literally Anything)

Here's something that surprises a lot of people: Japan doesn't care what your degree is in.

History? Fine. Engineering? Fine. Philosophy with a minor in medieval poetry? Also fine.

A bachelor's degree from an accredited university is required to get a work visa in Japan — but the subject doesn't matter one bit. The degree shows you can commit to something long-term, handle responsibility, and cross a finish line. That's what Japan's immigration system cares about.

2. A TEFL/TESOL Certification — And This One Actually Matters More Than People Think

Technically, a TEFL or TESOL certification is not written into Japanese immigration law as a visa requirement.

But here's real life: walk into any reputable language school in Japan without one and watch the HR manager politely — very politely — show you the door. Most private schools expect a 120-hour TEFL/TESOL certificate as a baseline. Many public school programs strongly recommend it. Even the competitive JET Programme looks more favorably on certified applicants.

Think of it like this: your degree gets your foot in the door. Your TEFL/TESOL certification gets you the job.

But there's something even more important than the paperwork side of it. Imagine standing in front of that classroom on day one with no training. Thirty students, a whiteboard, and... now what? A solid TEFL/TESOL course teaches you how to plan a lesson, how to explain grammar without making people fall asleep, how to handle the student who understands nothing and the student who already knows everything — at the same time. It gives you tools, confidence, and a structure to fall back on when things get weird. (And they will get weird. A student once tried to convince me that "I goed to school" was correct because his friend said so. True story.)

The good news? Getting TEFL/TESOL certified has never been easier or more flexible. An online 120-hour course — like UNI-Prep's accredited program — is fully accepted by Japanese employers, internationally recognized, and can be completed at your own pace from anywhere in the world. You can finish it in as little as two weeks.

No classroom required. No commute. Just you, the course material, and a certificate that opens doors across Japan.

3. A Clean Criminal Record

This is the serious one, so let's not joke around.

Japan is thorough when it comes to background checks. For most jobs, you'll need a national-level criminal record check — for Americans, that's an FBI check. For the JET Programme, it's mandatory, and any offense beyond minor traffic violations — including juvenile records — makes you ineligible.

For other teaching positions, a criminal record doesn't automatically close every door, but anything involving drugs, violence, or children will shut the vast majority of them. Japan has a zero-tolerance culture around these issues, and schools are not going to make exceptions.

If your record is clean, this is just a form to fill out. Move on.

4. A Clean Bill of Health (And a Drug-Free Lifestyle)

Japan's drug laws are strict in a way that might catch people off guard. Cannabis is illegal in Japan — full stop — regardless of what's legal in your home country. Schools conduct drug screenings, often randomly and repeatedly throughout your contract. This is not the country to test that particular boundary.

Beyond drug testing, most employers require a basic health check when you arrive — a physical exam, sometimes a blood test. For healthy applicants, this is a simple formality.

5. Strong English (Native or Very Close to It)

Japan generally prefers teachers from the "Big 7" English-speaking countries: USA, UK, Ireland, Canada, Australia, New Zealand, and South Africa. If you hold a passport from one of these countries, you're already at the front of the line for most jobs.

But here's the truth: Japan isn't exclusively looking for passport colors. It's looking for people who can communicate naturally and confidently in English. Non-native speakers with genuinely strong English skills do land teaching jobs in Japan — it just requires a bit more effort to demonstrate that fluency upfront.

And if your English is strong but your passport isn't from the Big 7? Your TEFL/TESOL certification becomes even more important, because it directly demonstrates your teaching competence and professional commitment.

6. The Right Age

There's no minimum age written into Japanese law for a work visa, but in practice, most schools want teachers to be at least 20 years old. The upper limit is generally around 60–65, reflecting Japan's culture around retirement age.

The sweet spot schools love? Teachers in their 20s and 30s. That said, older applicants with strong qualifications and flexibility about placement location do find positions — patience and a great application go a long way.

7. Some Startup Money in Your Pocket

Moving to Japan isn't free, and this is the part that catches a lot of first-timers off guard.

Budget for around ¥500,000 (roughly $3,300 USD) in savings before you arrive. Here's where that money goes:

  • Deposit: Usually 1–2 months' rent, paid upfront

  • Key money (reikin): A Japanese tradition — a one-time "gift" payment to your landlord of 1–3 months' rent that you don't get back. Not everyone charges it, but many do.

  • First month's rent: Also upfront

  • Setup costs: Bedding, kitchen basics, phone plan, transport card

  • The gap before your first paycheck: Usually 4–6 weeks

The good news: once you're settled, Japan's teacher salaries are among the best in Asia, and living outside Tokyo can stretch your yen remarkably far.


What Kind of Teaching Jobs Can You Get in Japan?

Once you have your qualifications sorted, you have real options — and they're all quite different.

Public School ALT Roles ALT stands for Assistant Language Teacher. You'll work alongside a Japanese teacher in elementary, junior high, or high schools. The famous JET Programme is the most well-known route here — government-backed, well-organized, and a fantastic way to experience Japan outside the major cities. Applications open October–November for the following year.

Private Language Schools (Eikaiwa) These schools teach everyone from toddlers to business executives. They hire year-round, tend to be concentrated in cities, and are often the fastest route to a teaching job in Japan. If you want Tokyo or Osaka and you want to start soon — eikaiwa is often your answer.

International Schools have higher pay (we're talking ¥400,000–600,000/month), but they require a recognized teaching license, not just a degree and TEFL certificate. If you're a licensed educator, this is the premium track.

Freelance and Private Tutoring A popular side income for teachers already in Japan. Rates run ¥2,000–6,000 per hour. Not a starting point, but a great supplement.

What Schools Actually Care About (That No One Puts on the Checklist)

Here's something that often surprises new teachers: the piece of paper matters, but so does the person holding it.

Japanese school culture places serious weight on:

  • Punctuality — being late is genuinely disrespectful in Japanese professional culture

  • Reliability — showing up, doing the job, every day, without drama

  • Flexibility — being open about your placement location, even if it's not Tokyo

  • Genuine curiosity about Japan — schools want people who are excited about being there, not just collecting a paycheck before moving on

And here's a little secret that every experienced teacher in Japan will tell you: learn a few Japanese phrases before you arrive. Even stumbling through a basic sumimasen (excuse me) or onegaishimasu (please) will earn you more goodwill than you'd expect. People appreciate the effort, even when the pronunciation is... creative.
