The 'Invisible Walls' of Disability Pension — Structural Barriers from Application to Receipt
Japan's disability pension non-approval rate hit a record 13.0% in FY2024, with mental disabilities seeing a near-doubling from the previous year. From proving the date of first medical examination to doctor refusals to regional certification gaps, structural barriers exist at every stage of the application process. Why does the system fail to reach those who need it?
TL;DR
- The FY2024 disability pension non-approval rate reached a record 13.0%; for mental disabilities, it was 12.1% — roughly double the previous year's 6.4%
- Prefectural non-approval rates ranged from 24.4% (Oita) to 4.0% (Tochigi) — a 6.1-fold gap (MHLW 2015 survey)
- Structural barriers at each stage — proving first exam dates, obtaining diagnosis certificates, and preparing medical history statements — make unassisted applications extremely difficult
What is happening
The FY2024 surge in non-approval rates and the tightening of mental disability certification
Disability pension is a public pension paid to individuals whose daily lives or work are restricted due to illness or injury, serving as a cornerstone of economic support for people with disabilities. In FY2024, however, something alarming occurred within this system.
According to a survey report by the Ministry of Health, Labour and Welfare (MHLW), the non-approval rate for new disability pension claims reached 13.0% — the highest level on record, up sharply from 8.4% in FY2023.
The situation is especially severe for mental and developmental disabilities. The non-approval rate for mental disabilities jumped from 6.4% in FY2023 to 12.1% in FY2024 — roughly doubling in a single year.
Even more striking is the change in the share of cases certified below the grade standard suggested by the mental disability guideline. This figure surged from 44.7% in FY2023 to 75.3% in FY2024 — meaning that three out of four cases received a grade lower than the guideline's benchmark, or were denied entirely.
An investigation by Kyodo News, which analyzed over 2,000 applications across FY2023 and FY2024 with the cooperation of multiple certified social insurance labor consultants, confirmed that non-approval rates for mental and developmental disabilities doubled year-on-year in 2024, with all disability types combined showing a 1.6-fold increase.
The total number of disability pension beneficiaries stands at approximately 2.22 million for Disability Basic Pension and 690,000 for Disability Employees' Pension. Any tightening of certification standards carries enormous implications.
Background and context
Structural barriers at each stage — proving first exam dates, obtaining diagnosis certificates, and preparing medical history statements
The application process itself is a barrier
The disability pension application involves six major steps. Structural barriers exist at every one of them.
Identify first examination date
⚠ Medical records destroyed or clinic closed
Verify premium payment history
⚠ Unpaid periods lead to automatic rejection
Request diagnosis certificate
⚠ Doctor refusal or inaccurate documentation
Prepare medical history statement
⚠ Must reconstruct decades of history
Submit to pension office
⚠ Returned due to document deficiencies
Certification review (3–4 months)
⚠ Variation by region and reviewer
The first-exam-date wall — unable to prove "when you first sought treatment"
The starting point for determining disability pension eligibility is the first medical examination date — the date when a doctor first examined the applicant for the condition causing the disability. Yet proving this date constitutes one of the system's most formidable structural barriers.
Medical institutions are only required to retain patient records for five years. For individuals with long treatment histories, it is common for the original clinic to have already discarded records or closed entirely. The Japan Pension Service provides guidance on alternative proof methods (such as third-party statements) when direct proof is unavailable, but the process is complex and places a heavy burden on applicants.
For mental and developmental disabilities, this problem becomes even more acute. Initial symptoms may emerge during adolescence without being recognized as the "first consultation" for a condition that would later qualify for disability pension. Requiring proof of a first examination from twenty years ago is a structurally disadvantageous design for applicants.
The diagnosis certificate wall — doctors who "won't write it"
Disability pension applications require a diagnosis certificate in a prescribed format. However, a significant number of doctors refuse to prepare disability pension diagnosis certificates.
The reasons are multi-layered: physicians' value judgments that "receiving a pension will reduce motivation for treatment," the time burden of completing a complex form, and insufficient knowledge of the disability pension system itself. Together, these create a structural pattern of certificates being "unobtainable."
An equally serious problem occurs when the content of a completed certificate fails to reflect the applicant's actual living conditions. In brief consultations, the full extent of daily life difficulties may not be communicated, resulting in the disability being documented as milder than reality. This creates the risk of a condition warranting Grade 2 being assessed as Grade 3 — or denied entirely.
The medical history statement wall — reconstructing decades of memory
The "Medical History and Work Status Statement" requires applicants to describe their condition's progression chronologically from onset to present. For those with decades-long treatment histories, this demands an arduous reconstruction of memory.
Moreover, the way this statement is written can significantly influence the review outcome. Even with identical disability conditions, whether daily life difficulties are articulated appropriately can determine the certification result. The going rate for social insurance labor consultants to handle applications — typically two to three months' worth of pension payments as a success fee — itself speaks to how inaccessible the system is without professional support.
Reading the structure
Regional gap data and the structural problem of certification criteria skewed toward the medical model
Regional gaps — where you live determines the outcome
A survey published by the MHLW in 2015 shook the foundations of the disability pension system.
Comparing prefectural non-approval rates for new Disability Basic Pension claims filed over the three-year period from FY2010 to FY2012, the survey found that the gap between the highest — Oita Prefecture at 24.4% — and the lowest, Tochigi Prefecture at 4.0%, was a staggering 6.1-fold (this data predates the September 2016 guideline introduction; no comprehensive follow-up survey on the extent to which the regional gap has been corrected has been published).

The primary driver of this gap lay in differences in how certification standards for mental and intellectual disabilities were applied. With mental and intellectual disabilities accounting for 66.9% of new applications, the operational use of "Degree of Daily Living Ability" (a five-point scale) was not standardized across regions.
The ten prefectures with the lowest non-approval rates used the second level or above on the five-point scale as the benchmark for approval, while the ten prefectures with the highest non-approval rates required the third level or above. In other words, whether the same disability qualified for benefits depended on where the applicant lived.
In response, the "Guideline for Grade Assessment of Mental Disabilities" was introduced in September 2016 to centralize review standards. However, as FY2024 data shows, with 75.3% of cases being certified below the guideline's benchmarks, the guideline itself appears to be losing its intended function.
The structure of certification criteria — over-reliance on the medical model
The Japan Federation of Bar Associations (JFBA) issued a presidential statement in July 2025 demanding reform of disability pension certification criteria. A second statement followed in January 2026.
The fundamental problem identified by the JFBA is that Japan's disability pension certification criteria are over-reliant on the medical model of disability. The current criteria evaluate physical functional impairment medically and assign grades based on severity. However, particularly for mental and developmental disabilities, medical diagnoses and test values alone cannot adequately capture the realities of daily life difficulties.
Within the Social Security Council's Pension Subcommittee, disability pension reform appeared on the agenda in only approximately two of its 24 sessions. The 2025 legislative reform included no concrete changes to disability pension provisions, settling for supplementary resolutions. The structural deprioritization of reform discussions is itself part of the problem.
The narrow gate of appeals
Those who receive non-approval decisions may file an administrative review request with a Social Insurance Examiner. However, the rate at which decisions are overturned (accepted) through this process is approximately 4%. Even including re-examination requests to the Social Insurance Review Board, the probability of reversing a non-approval decision remains extremely low.
This narrowness of the "exit" underscores the critical importance — and the problem of arbitrariness — in the initial certification stage.
The "invisible walls" of disability pension cannot be attributed to a single cause. The difficulty of proving the first examination date, the diagnosis certificate barrier, the complexity of the medical history statement, regional gaps, over-reliance on the medical model, and the narrow gate of appeals — all operate in combination to create a structure where "the system exists but fails to reach those who need it."
Non-take-up is not a problem confined to public assistance. In disability pension as well, there is a need to confront the structural factors that prevent eligible individuals from applying, or that result in denials even when they do.
The legitimacy of a social security system is sustained not only by "preventing fraudulent claims" but by "reaching those who need it." The surge in non-approval rates in FY2024 is a warning that this system is losing the latter function.
