Introduction: Why focus on the most recent four years
The written portion of Japan's national sign-language interpreter certification exam shifts its focus over time as laws are revised and society changes. A full run of the data tells you the "all-time staples," but to grasp the most recent trend in what is being tested, an analysis narrowed to the latest four years (2021-2024) is essential.
In this article I pull out only the data from those recent four years to reveal both the "staple themes that appear without fail every year" and the "new-trend themes that never appeared in 2011-2016." Read alongside the all-time trend analysis, it brings your study priorities into much sharper focus.
How I analyzed the data
I systematically organized the contents of the five textbooks that make up the exam syllabus, then used my own record of which terms had actually appeared, following the steps below.
| Item | Definition |
|---|---|
| Recent period | 2021, 2022, 2023, 2024 (four years) |
| Earlier period | 2011, 2012, 2013, 2014, 2015, 2016 (six years) |
| Staple themes | Terms tested in all four of the recent years |
| Near-staple themes | Terms tested in three of the recent four years |
| New-trend themes | Terms tested in the recent four years but with no record of appearing in the earlier six years |
Between the earlier period and the recent period there is a gap of 2017-2020 (no past-exam data), so this is not a fully continuous data set. Even so, a six-year vs. four-year comparison has more than enough precision to detect shifts in what is being tested.
The 7 staple themes (tested four years running)
The themes that appeared every single year across the recent four years are the following seven. These are the most important themes of all - the ones you can flatly call "guaranteed to appear" - and you need to understand them perfectly.
| # | Term | Category | All-time |
|---|---|---|---|
| 1 | Japanese Federation of the Deaf (Zen Nihon Rou-a Renmei) | Mindset of a sign-language interpreter | Tested every year |
| 2 | I Love Communication (the JFD handbook) | Mindset of a sign-language interpreter | Tested every year |
| 3 | Honorific expressions (respectful, humble, polite forms) | How language works | Tested every year |
| 4 | Social work | Introduction to social work | Tested nearly every year |
| 5 | Health management for sign-language interpreters | Interpreter registration system | Tested nearly every year |
| 6 | Hearing aids | Basics of hearing disability | Tested nearly every year |
| 7 | Basic Act for Persons with Disabilities | Introduction to disability welfare | Tested often |
Point: Six of the seven staple terms also rank in the TOP 10 across the full nine-year run. The "Basic Act for Persons with Disabilities" appeared in six of the nine years all-time, but in the recent four years it has appeared every single year - a sign that its importance has been rising in recent years.
The 28 near-staple themes (tested in 3 years)
Twenty-eight themes were tested in three of the recent four years. This is the group with the next-highest study priority after the staple themes.
| # | Term | Category | Frequency |
|---|---|---|---|
| 1 | Act on Welfare of Physically Disabled Persons | Introduction to disability welfare | Nearly every year |
| 2 | Comprehensive Support for Persons with Disabilities Act | Basics of disability welfare | Nearly every year |
| 3 | Act for Eliminating Discrimination against Persons with Disabilities | Introduction to disability welfare | Nearly every year |
| 4 | Convention on the Rights of Persons with Disabilities | Introduction to disability welfare | Nearly every year |
| 5 | Act on Certified Social Workers and Certified Care Workers | Basics of disability welfare | Nearly every year |
| 6 | Certified Sign-Language Interpreter examination | Interpreter registration system | Nearly every year |
| 7 | ICF (International Classification of Functioning, Disability and Health) | Introduction to disability welfare | Nearly every year |
| 8 | Real-time captioning (yoyaku hikki) | Basics of hearing disability | Nearly every year |
| 9 | Sign-language ordinances | Mindset of a sign-language interpreter | Nearly every year |
| 10 | National Training Center for Sign-Language Interpreters | Interpreter registration system | Nearly every year |
| 11 | Sign-language volunteer workers | Volunteer activities | Nearly every year |
| 12 | The social model (of disability) | Introduction to disability welfare | Nearly every year |
| 13 | Integration | Language development in deaf children | Nearly every year |
| 14 | Cochlear implants | Basics of hearing disability | Nearly every year |
| 15 | Neck-shoulder-arm disorder (keikenwan shougai) | Interpreter registration system | Nearly every year |
| 16 | Duty of confidentiality | The philosophy and work of interpreting | Nearly every year |
| 17 | Biestek's seven principles | Introduction to social work | Nearly every year |
| 18 | Homophones (doon-igigo) | How language works | Nearly every year |
| 19 | Four-character idioms (yojijukugo) | Japanese language (idioms & four-character compounds) | Nearly every year |
| 20 | Idiomatic phrases (kan'youku) | Japanese language (idioms & four-character compounds) | Nearly every year |
| 21 | History of deaf education | Language development in deaf children | Nearly every year |
| 22 | Communication support services | Basics of disability welfare | Nearly every year |
| 23 | Act on Information Accessibility for Persons with Disabilities | Introduction to disability welfare | Nearly every year |
| 24 | Conductive and sensorineural hearing loss | Basics of hearing disability | Nearly every year |
| 25 | Hearing tests (audiometry) | Basics of hearing disability | Nearly every year |
| 26 | The three elements of interpreting (comprehending the source, converting, producing) | The philosophy and work of interpreting | Nearly every year |
| 27 | Deaflympics | Basics of hearing disability | Nearly every year |
| 28 | Sign-language interpreting in disasters | The philosophy and work of interpreting | Nearly every year |
Adding the 28 near-staple terms to the 7 staple terms gives 35 terms in all. By my reckoning, that covers the great majority (an estimated 15-17) of the 20 general-knowledge questions in the recent four years.
Comparison with the earlier period (2011-2016)
Of the seven staple terms, four - the Japanese Federation of the Deaf, I Love Communication, honorific expressions, and social work - were already tested frequently in the earlier period too. In other words, they are "super-staples" that have not changed in more than ten years.
The Basic Act for Persons with Disabilities, on the other hand, was tested in three years during the earlier period but has been promoted to every year in the recent four. Themes whose importance grew after Japan ratified the Convention on the Rights of Persons with Disabilities (2014) - such as the social model and the ICF - have also risen in frequency recently.
| Term | Earlier (of 6 years) | Recent (of 4 years) | Change |
|---|---|---|---|
| Japanese Federation of the Deaf | 6 years | 4 years | Unchanged (super-staple) |
| Honorific expressions | 6 years | 4 years | Unchanged (super-staple) |
| Basic Act for Persons with Disabilities | 3 years | 4 years | Rising frequency |
| The social model | 0 years | 3 years | New trend |
| ICF | 0 years | 3 years | New trend |
| Act on Information Accessibility for Persons with Disabilities | — | 3 years | New law |
| Deaflympics | 0 years | 3 years | New trend |
The 106 new-trend themes
There are 106 themes with no record of appearing in the earlier period (2011-2016) that were tested for the first time in the recent four years (2021-2024). These are the exam's "new face," and they are highly likely to keep appearing going forward.
The breakdown of those 106 terms by number of appearances is as follows.
| Appearances | Number of terms | Examples |
|---|---|---|
| 3 years (near-staple) | 14 terms | The social model, ICF, Act on Information Accessibility for Persons with Disabilities, Deaflympics |
| 2 years | 35 terms | Reasonable accommodation, Sign-Language Policy Promotion Act, remote sign-language services, CRPD |
| 1 year | 57 terms | SDGs, young carers, supported decision-making, CART |
Worth noting: Many of the 106 new-trend terms relate to the legal reforms and international developments that followed Japan's ratification of the Convention on the Rights of Persons with Disabilities (2014). It reflects the exam actively incorporating "the latest welfare policy."
How the new trends break down by category
Looking at which categories the 106 new-trend terms cluster in lets you predict where future questions are heading.
| Category | New-trend terms | Main themes |
|---|---|---|
| Introduction to disability welfare | 28 terms | The social model, reasonable accommodation, CRPD, Act on Prevention of Abuse of Persons with Disabilities |
| Basics of hearing disability | 15 terms | Deaflympics, remote sign-language services, telephone relay service |
| The philosophy and work of interpreting | 14 terms | Disaster interpreting, medical interpreting, legal/court interpreting |
| Introduction to social work | 12 terms | Strengths perspective, empowerment, advocacy |
| Language development in deaf children | 10 terms | Bilingual deaf education, the "9-year-old wall," language deprivation |
| Mindset of a sign-language interpreter | 9 terms | Sign-language ordinances, Sign-Language Policy Promotion Act, language rights |
| Other | 18 terms | Japanese language (new loanwords), volunteer activities, registration system |
"Introduction to disability welfare" tops the list with 28 terms. Laws and systems tied to the Convention on the Rights of Persons with Disabilities have expanded dramatically, and keywords that never appeared in the earlier period - such as "the social model," "reasonable accommodation," and "supported decision-making" - have become frequent.
Putting this to work in your study plan
Here are concrete steps for building the data in this article into your study plan.
Step 1: Master the 7 staple terms perfectly
The seven terms tested four years running are confirmed to appear. Go beyond the definitions and dig down into the related laws, systems, and historical background.
Step 2: Cover the 28 near-staple terms
Adding the 28 terms tested in three years brings you to 35 terms, which covers the bulk of recent questions. Focus your reading on the relevant sections of the textbooks.
Step 3: Skim the 106 new-trend terms
The 14 terms tested in "3 years" and the 35 terms tested in "2 years" in particular are highly likely to keep appearing. Nail down their definitions and background.
Step 4: Study alongside the all-time data
There are "cycles" in what is tested that the recent four-year data alone cannot reveal. Combining it with the all-time trend analysis lets you build a more precise study plan.
Priority summary: 7 staple terms → 28 near-staple terms → 14 new-trend terms (3 years) → 35 new-trend terms (2 years) → the rest. Study in this order and you will get the most out of limited time.
