Best TEFL Certification for Japan: What Employers Actually Accept

The best TEFL certification for Japan is not simply the cheapest or fastest option online: it is the qualification that matches what your target employer, whether that is the JET Programme, a dispatch ALT company, an eikaiwa chain or an international school, will actually accept at interview stage. Japan’s teaching market is more paperwork-driven and hierarchy-conscious than many other Asian destinations, so choosing the right course level from the outset saves months of wasted applications later.

This guide sets out exactly what Japanese employers ask for, course by course, hour by hour, using our own certification levels as the working example, then walks through realistic 2026 salaries, the visa and Certificate of Eligibility timeline, and the document checks you will face before you ever board a flight. It also explains why our membership of the Ireland Japan Chamber of Commerce matters if you are applying from Ireland.

What is the best TEFL certification for Japan right now?

The best TEFL certification for Japan is a minimum 120 hour course for entry level eikaiwa and dispatch ALT roles, but a Level 5 Ofqual regulated Diploma of 180 hours or more for JET-style public school placements, international schools and any role where you are competing against degree-holders with classroom experience. Employers rarely reject a 120 hour certificate outright, but a Level 5 Diploma consistently wins interviews when the applicant pool is large.

Which of our course levels match Japanese employer requirements?

Because Japan’s employers range from budget eikaiwa chains to prestigious international schools, it helps to see our course levels lined up against what each type of employer typically expects. The table below uses our own course pages as the reference point, since these are the exact qualifications most of our Japan-bound graduates complete.

If you already hold a degree and simply want the minimum credential a dispatch ALT company or eikaiwa will process without delay, the 120 hour course does the job. If you are applying anywhere near Tokyo, Osaka or any of the larger international school networks, the jump to a Level 5 Diploma is worth the extra study time, because it is explicitly called out by name in a growing number of Japanese job listings.

What hours and level does JET actually require?

The JET Programme itself does not mandate a TEFL certificate at all: its formal entry route runs through a Bachelor’s degree, a clean background check and, for non-native English backgrounds, evidence of at least twelve years of English medium schooling. In practice, however, JET’s own recruitment webinars and affiliated recruiters now recommend a 120 hour TEFL certificate as a practical minimum, since it strengthens an application against thousands of degree-only competitors.

What hours and level do eikaiwa chains require?

Eikaiwa chains such as the larger private conversation school groups generally accept a 120 hour TEFL certificate alongside a Bachelor’s degree, and rarely insist on anything beyond that for entry level teaching positions. Some of the more established chains now give hiring priority, and occasionally a small pay increment, to applicants holding a Level 5 Diploma, particularly for positions involving business English or corporate in-company classes.

What hours and level do dispatch ALT companies require?

Dispatch ALT companies, which place assistant language teachers into public schools on behalf of local boards of education, typically require the same baseline as eikaiwa: a Bachelor’s degree plus a 120 hour TEFL certificate. Competition for the better-paid dispatch contracts has increased, so a Level 5 Diploma is now a genuine differentiator when two similarly qualified candidates are being compared for the same placement.

What hours and level do international schools require?

International schools sit at the top of the Japanese teaching market and usually expect either a recognised teaching licence or a Level 5 TEFL Diploma of 180 hours or more, frequently alongside prior classroom experience or a postgraduate qualification in education. A 120 hour certificate alone is very rarely sufficient here, which is why our 180 hour and 300 hour Diplomas exist specifically for teachers targeting this tier of the market.

What can you realistically earn teaching English in Japan in 2026?

Pay in Japan varies more by employer type than by city, and the route you choose changes both your starting salary and how quickly it rises. The table below sets out realistic 2026 monthly figures across the four main employer categories, converted to euro at an approximate rate of €1 to ¥185 (July 2026).

JET’s own published pay scale rises in fixed steps through five years of service, reaching around ¥4.32 million a year by year four, which makes it one of the more predictable routes financially. Dispatch ALT and eikaiwa pay tends to stay flatter year on year unless you move into a training or senior teaching role, while international schools offer by far the widest range, reflecting the mix of qualifications and experience levels they hire across.

How do you apply for a TEFL job in Japan step by step?

The path from finishing a TEFL course to teaching in a Japanese classroom typically follows a predictable sequence, though the exact timing depends heavily on whether you are applying to JET, a dispatch company or an eikaiwa.

1. Complete your TEFL certification. Finish a 120 hour course for eikaiwa or dispatch roles, or a Level 5 Diploma of 180 hours or more if you are targeting JET-adjacent placements, international schools or the more competitive dispatch contracts.
2. Apply to your chosen route. JET runs a single annual application cycle (typically opening in autumn for the following summer’s intake); dispatch ALT companies and eikaiwa recruit year-round, with hiring spikes ahead of the April and September school terms.
3. Attend interviews. Expect an initial screening call, a demonstration lesson delivered over video, and for JET, an in-person or consulate interview in your home country.
4. Receive your job offer and Certificate of Eligibility (COE) application. Once hired, your employer or JET’s coordinating body files the COE application with Japan’s Immigration Services Agency on your behalf, since as the sponsored applicant you cannot file it yourself from overseas.
5. Wait for COE approval. Processing generally takes one to three months, so this is usually the single longest step in the whole timeline.
6. Apply for your work visa. Once the COE arrives, take it to your nearest Japanese embassy or consulate along with your passport and application form; visa issuance is normally quick, often within a week.
7. Travel and begin orientation. JET and most large dispatch companies run a short orientation programme in Japan before you start teaching, usually lasting a few days to a week.

Altogether, most applicants should budget three to six months from finishing their TEFL course to standing in front of a Japanese classroom, with the COE stage being the part least within your control.

Do your TEFL documents need to be legalised for Japan?

Japan has been a member of the Hague Apostille Convention since 1970, which means documents issued in another member country, including your degree certificate, TEFL certificate and criminal background check, generally only need a single apostille stamp from the relevant authority in your own home country. This is considerably simpler than the multi-step consular legalisation process required for countries such as China, Vietnam or Taiwan, which are not Apostille Convention members.

In practice this means an Irish graduate would get their documents apostilled through Ireland’s Department of Foreign Affairs rather than visiting the Japanese embassy for legalisation, and the same principle applies to applicants from the UK, the US, Canada, Australia and most of the EU. A clean criminal background check remains one of the most commonly requested documents across every route, JET included, so it is worth ordering this early given it can itself take several weeks to process.

Why does Ireland Japan Chamber of Commerce membership matter for TEFL applicants?

The TEFL Institute Group is now a Corporate Member of the Ireland Japan Chamber of Commerce (IJCC), based in Dublin. Membership does not grant anyone a visa or a job, but it strengthens our direct relationships with Japanese employer contacts, gives us better local hiring intelligence, and connects our graduates to a wider network of partners already active in the Japanese education sector, including a partnership with a dedicated Japan job board.

For Irish TEFL graduates specifically, this membership sits alongside practical routes such as the Working Holiday Visa for applicants aged 18 to 30, which is one of the few exceptions to the standard degree-plus-TEFL requirement most other routes require. Irish readers can see how this plays out in more detail on our sister site’s dedicated page on Irish teachers in Japan and chamber membership.

Is a 120 hour TEFL certificate enough for Japan?

A 120 hour TEFL certificate is enough for most eikaiwa chains and dispatch ALT companies, which treat it as the accepted industry minimum alongside a Bachelor’s degree. It becomes insufficient once you are applying to international schools, university-affiliated programmes, or any dispatch contract where you are competing against a large pool of similarly qualified applicants, all of which increasingly favour a Level 5 Diploma of 180 hours or more.

How does Japan compare with other Asian TEFL destinations?

Compared with much of Southeast Asia, Japan asks for slightly more paperwork rigour but rewards it with generally higher, more stable pay and stronger institutional support through routes like JET. South Korea’s EPIK programme runs a broadly similar government-supported model, while destinations such as Thailand, Cambodia and Vietnam tend to accept a 120 hour certificate more universally across all employer types, with fewer roles specifically demanding a Level 5 Diploma. If Japan’s document and interview process feels heavier than you expected, that rigidity is largely a reflection of Japan’s broader employment culture rather than anything specific to teaching.

What should you do after finishing your TEFL certificate?

Once your certificate is in hand, the practical next step is deciding which route matches your qualifications, budget and appetite for structure. Graduates of our 190 Hour Hybrid Level 5 TEFL Diploma are well positioned for dispatch ALT and eikaiwa applications immediately, while those holding our 300 Hour Regulated Level 5 Advanced TEFL Diploma are better placed for international school and business English roles inside Japanese companies. From there, start building your document file early: order your background check, gather your degree certificate, and get everything ready for apostille well before you plan to submit any application, since this preparatory stage is where most avoidable delays happen.

For a broader look at what daily life and budgeting look like once you arrive, our guide on the cost of living in Japan for new English teachers is a useful next read, and if you are still deciding between Japan and a neighbouring market, TEFL Japan vs South Korea lays out the practical differences for American applicants in particular. Those specifically interested in the JET route should also read our dedicated JET Programme guide, and anyone still weighing up cities can compare pay and lifestyle in our Japan city salary guide.

Choosing the best TEFL certification for Japan ultimately comes down to being honest about which employer tier you are aiming for. A 120 hour certificate will open real doors at eikaiwa chains and dispatch ALT companies, but if international schools, competitive dispatch contracts or business English roles are the goal, investing in a Level 5 Diploma from the outset will save you from re-training later once you discover a listing you cannot apply to.
