EIKEN vs IELTS: They Answer Different Questions

Comparison posts usually rank the two exams. Ranking them is the mistake.

One is pass or fail on a grade. The other is a band you cannot fail.

Key takeaways

EIKEN awards a grade you pass or fail; IELTS awards a band you cannot fail.
The only bridge between them is CEFR, and each board publishes its own comparison to it.
EIKEN's speaking test is a separate second stage roughly a month later.
IELTS Speaking is 11 to 14 minutes in three parts, inside the same test event.
EIKEN's published anchors are Japanese ministry benchmarks for school stages and instructors.
The choice is usually made by whoever you need the certificate for.

The difference that decides everything

Everything else follows from how the two exams report a result.

EIKEN reports a grade. You enter for Grade 2, or Pre-1, or Grade 1, and you pass it or you do not. The level is chosen before you sit down, and the outcome is binary. That is why the ladder has eight positions and three half steps, which we set out in Pre-1 and Pre-2 explained and seven or eight grades.

IELTS reports a band. You sit one test and receive a score on a scale from 0 to 9, in half band increments. There is no entry level to choose and no failing, only a number that either meets your destination's requirement or does not.

Those are different products solving different problems. A grade system suits a learner climbing over years and needing visible steps. A band system suits an applicant who needs one number compared against one threshold.

So "which is harder" dissolves on contact. Difficulty in EIKEN is a property of the grade you entered. Difficulty in IELTS is a property of the band somebody else demands of you.

The only honest bridge is CEFR

People still need a rough sense of where a grade sits, so here is the accurate version of how that works.

The Eiken Foundation publishes a comparison of its grades against the CEFR. IELTS publishes a comparison of its bands against the CEFR. Neither board publishes a direct conversion to the other.

That means any EIKEN to IELTS table is doing two hops through a third scale, and precision is lost at both. The CEFR itself is a broad framework of ability descriptors, not a scoring instrument, so a single CEFR level covers a wide range on either exam's own scale. We found exactly that inside EIKEN alone, where score bands overlap across grades, in the CSE score overlap.

Use CEFR to orient yourself, never to plan. If a university or an immigration route names a band, that number is the requirement, and a CEFR equivalence argument will not substitute for it. The mapping between IELTS bands and the visa levels is set out in the UKVI band table, and what a specific band feels like in practice in what band 7 means.

Side by side

	EIKEN	IELTS
Result	Grade, pass or fail	Band 0 to 9
Level chosen	Before you sit	Not chosen
Speaking	Separate second stage, about a month later	Same test event
Speaking length	Interview at a public test site	11 to 14 minutes, three parts
Published anchors	Japanese ministry benchmarks	Institutional and visa requirements
Past papers	Every first stage released free with audio	Practice material, mostly commercial
Main population	Japanese school students	International applicants

The free past paper row is worth pausing on. The Foundation releases every first stage administration with audio at no cost, which we covered in EIKEN past papers are free. That is unusual, and it is a genuine advantage for the written stage that has no equivalent on the other side.

The speaking tests are not comparable

This is where superficial comparisons do the most damage, because both are called a speaking test and they sit in completely different places.

EIKEN's speaking test is a second stage. You pass the first stage, then return roughly a month later to a public test site for a face to face interview conducted entirely in English. Two separate events, weeks apart, with a known date between them. The top grade uses two examiners, which we cover in Grade 1's two examiners, and the bottom two grades use an optional recorded test that cannot fail you, in Grade 4 and 5 speaking.

IELTS Speaking is 11 to 14 minutes inside the test event, in three parts with an examiner: an introduction and interview, a long turn from a task card, and a discussion.

The consequences for preparation are opposite.

EIKEN's month long gap is an asset if you use it, because you know your date and you have one skill left to work on. The risk is treating it as a rest between exams. We set out the exact gaps from the published calendar in EIKEN test dates 2026 to 2027.

IELTS gives you no such window. The speaking test arrives with the rest of it, so speaking practice has to be part of the whole preparation rather than a phase at the end. Our routines for that are in how to practise IELTS speaking at home and how to practise alone.

Usually the choice is already made

Most people asking which exam to take do not actually have the choice, and finding that out early saves weeks.

Check what your destination accepts, first and only. A university, an employer, a registration body or an immigration route names the tests it accepts and often the exact score. That list ends the debate.

EIKEN's recognition is concentrated in Japan. The published grades table ties grades to ministry benchmarks at junior high graduation, high school graduation and English instructor level, and lists Grade 1 against international admissions. The scale behind that is in why EIKEN is Japan's national English test, and the population that sits it in who actually takes EIKEN.

IELTS travels further. It appears in immigration rules, university admissions and professional registration across many English speaking countries, which is why it dominates any list of accepted tests. The survey of what different bodies actually demand is in every English requirement we have read.

If both are accepted, pick on structure rather than reputation. Someone who performs better with a known date and one skill to focus on will prefer the two stage shape. Someone who wants a single sitting and a number will prefer the band.

What transfers and what does not

Preparation splits cleanly into two piles.

The language transfers completely. Vocabulary, listening comprehension, fluency, pronunciation and the ability to hold an unscripted conversation are the same assets in both exams, and they are the slow part.

The technique does not. Clearing a fixed bar and maximising a band score are different tasks. Grade preparation rewards knowing precisely what a level requires and stopping there. Band preparation rewards sustained best performance across criteria, because every increment counts.

The speaking practice transfers most of all, which is the useful conclusion. Whatever the format, both exams put you in front of a person and ask you to talk. Nobody can revise that for you, and neither board publishes a past paper for it.

That is what SpeakShark is built for: unscripted conversation with native accent AI teachers plus instant phoneme level feedback on the sounds that keep tripping you. The free plan is three sessions a day with no card, the pricing page shows the paid tier, how it works explains the mechanics, and our comparison of speaking apps is honest about the limits, including ours.

For a third reference point on how boards describe spoken performance, Cambridge speaking criteria by level sets out published descriptors across a ladder that is spaced by CEFR level rather than by school stage.

What we could not verify

Neither board publishes a direct EIKEN to IELTS conversion, and we did not find one. Everything above about relating the two goes through CEFR and we say so each time.

We did not read a complete list of institutions outside Japan that accept EIKEN, so we describe its recognition as concentrated rather than limited to Japan.

We did not compare fees, because they vary by country and by application route and we did not read a current fee table for either exam.

We make no claim about which exam is easier at any given level, and we would treat any source that does with suspicion.

How we researched this guide

The EIKEN grade structure, the ministry benchmarks and the CEFR comparisons come from the Eiken Foundation of Japan's EIKEN Grades page, the two stage format and the approximately one month gap from its speaking tests page, the calendar from its test administration page and the free past paper release from its preparation page, all opened directly in a browser. The IELTS speaking format and length and the band scale come from ielts.org, opened directly. The CEFR global scale comes from the Council of Europe. Where we relate the two exams, we route through CEFR explicitly and label the limits of doing so.

We are a speaking improvement tool. We are not an exam preparation provider, and we are not affiliated with the Eiken Foundation of Japan, the IELTS partners or any exam board.

FAQ

Is EIKEN or IELTS harder?

The question does not have an answer, because they are not scored on the same kind of scale. EIKEN awards a grade you pass or fail, so difficulty is fixed by which grade you enter. IELTS awards a band from 0 to 9 that you cannot fail, so difficulty is set by whichever band your destination demands. Grade 1 is a demanding target and band 8 is a demanding target, and neither is the same exam problem.

Can I convert an EIKEN grade into an IELTS band?

Not directly, and any table that claims to is doing something the two boards do not. Each publishes its own comparison to the CEFR, so the only bridge between them is that third scale, and comparing through a third scale loses precision at every hop. Use CEFR to get a rough sense of where a grade sits, then check what your actual destination accepts.

Which one should I take?

Whichever the organisation you need something from accepts, which is usually decided before you get a say. EIKEN's recognition is concentrated in Japan, where the published grades table ties grades to ministry benchmarks for school stages and for English instructors. IELTS is the currency for immigration, university admission and professional registration across many English speaking countries.

How do the speaking tests differ?

Structurally, more than most comparisons admit. EIKEN's speaking test is a separate second stage held roughly a month after the written paper, at a public test site, and it is face to face. IELTS Speaking is 11 to 14 minutes with an examiner in three parts and is part of the same test event. So EIKEN gives you weeks of warning and a separate trip; IELTS gives you one sitting.

Does taking one help with the other?

The English improves either way, and the exam technique mostly does not transfer. Two stage pass or fail preparation trains you to clear a fixed bar; band scale preparation trains you to produce your best sustained performance across four criteria. The overlap is the language itself, which is the part worth working on regardless of which test you end up sitting.
