Car Tax Reduction for People with Disabilities in Japan

If you or a family member has a disability handbook in Japan, you may be eligible for a reduction or full exemption on the annual automobile tax (jidousha zei shubetsu wari / 自動車税種別割). This benefit can also apply to the automobile tax on vehicle acquisition (jidousha zei kankyou seinou wari / 自動車税環境性能割) when purchasing a car, and to the light vehicle tax (kei jidousha zei / 軽自動車税) for smaller vehicles.
This is a prefectural program (todoufu ken / 都道府県), which means the specific eligibility criteria, the amount of the reduction, and the application process can vary depending on where you live. Please always confirm the specific rules with your prefectural tax office.
Who Qualifies?
All three types of disability handbooks can qualify for the car tax reduction, but the eligible grades and disability categories differ by handbook type and by prefecture. Here is a general overview of how it works in most prefectures:
Shintai Shougaisha Techou (身体障害者手帳) / Physical Disability Handbook
Eligibility depends on both the disability category and the grade. Not all grades qualify. In general, people with more severe grades in categories related to mobility are more broadly eligible. The disability categories include visual impairment, hearing impairment, balance/vestibular impairment, speech impairment, upper limb impairment, lower limb impairment, trunk impairment, and internal organ conditions (heart, kidney, respiratory, bladder, liver, and immune system).
Each prefecture publishes a detailed table showing exactly which disability categories and grades qualify. For example, lower limb impairment may qualify at grades 1 through 6 for self-driving, but only at grades 1 through 3 for caretaker driving. Internal organ conditions may qualify at grades 1 and 3 only. The specifics vary, so check your prefecture’s table.
Important: If you have more than one disability listed on your handbook, the eligibility is determined by the grade of each individual disability category, not by the overall grade on the handbook. For example, if your handbook says grade 3 overall but that is a combination of two separate disabilities each graded lower, you may not qualify. Check with your prefectural tax office.
Ryouiku Techou (療育手帳) / Intellectual Disability Handbook
In most prefectures, all grades of the ryouiku techou qualify for the car tax reduction. In Tokyo, the ai no techou (愛の手帳) follows the same principle. Check your prefecture’s rules to confirm.
Seishin Shougaisha Hoken Fukushi Techou (精神障害者保健福祉手帳) / Mental Health and Welfare Handbook
In most prefectures, only Grade 1 qualifies for the car tax reduction. In addition, many prefectures require the person to also hold a jiritsu shien iryou jukyuusha shou (自立支援医療受給者証, self-support medical care handbook) for mental health outpatient treatment (seishin tsuuin iryou / 精神通院医療) as proof that the person is receiving ongoing treatment. Both documents must be presented when applying.
Self-Driving and Caretaker Driving
Like the ETC highway toll discount, the car tax reduction has two categories:
- Self-driving (honnin unten / 本人運転): The person with the disability is the driver. This applies to shintai shougaisha techou holders whose disability allows them to drive.
- Caretaker driving (kazoku unten or joujitsu kaigo sha unten / 家族運転・常時介護者運転): A family member or regular caregiver drives the car, and the person with the disability is a passenger. This applies when the person with the disability cannot drive themselves.
For caretaker driving, the eligible grades are often more restricted than for self-driving. In many prefectures, the person with the disability must have a more severe grade to qualify under the caretaker driving category.
The caretaker driver must be someone who lives with the person with the disability (seikei wo onaji ku suru mono / 生計を同じくする者) or, in some prefectures, someone who regularly provides care (joujitsu kaigo sha / 常時介護者). “Living together” generally means being in the same household, but some prefectures also accept family members living within a short distance (for example, within 2 km in Tokyo).
Which Car Qualifies?
- One car per person. The reduction applies to one car per person with a disability. If you already receive the light vehicle tax reduction from your municipality, you cannot also receive the automobile tax reduction from the prefecture for a second car.
- Private use only. The car must be registered as a private vehicle (jikayou / 自家用). Commercial vehicles do not qualify.
- Ownership. The car is generally registered in the name of the person with the disability. However, if the person is under 18, has an intellectual disability, or has a mental health disability and does not drive, the car can be registered in the name of a family member who lives with them.
How to Apply: Step by Step
Step 1: Check your prefecture’s eligibility criteria. Before anything else, look up your prefecture’s disability car tax reduction page. Every prefecture publishes the specific disability categories, grades, and conditions that qualify. The links for Saitama and Tokyo are in the Useful Resources section below.
Step 2: Gather your documents. You will typically need:
- A disability handbook (shougaisha techou / 障害者手帳)
- The vehicle inspection certificate (jidousha kensashou / 自動車検査証), also called shaken shou (車検証)
- The driver’s license (unten menkyoshou / 運転免許証) of the person who drives the car
- For seishin techou holders: the jiritsu shien iryou jukyuusha shou (自立支援医療受給者証) as well
- For caretaker driving: proof that the driver lives with or regularly cares for the person with the disability (a residence handbook showing the same household, or a joujitsu kaigo sha no seiyaku sho / 常時介護者の誓約書, a caretaker pledge form provided by the tax office)
- Your personal seal (inkan / 印鑑)
Step 3: Apply at the prefectural tax office. For automobile tax (regular-size vehicles), apply at either:
- Your prefectural tax office (kenzei jimusho / 県税事務所), or
- The automobile tax office (jidousha zei jimusho / 自動車税事務所)
For light vehicle tax (kei jidousha zei / 軽自動車税), apply at your city or ward office (shiyakusho / 市役所 or kuyakusho / 区役所), since light vehicle tax is a municipal tax.
Some prefectures now accept applications by mail or online. Check your prefecture’s page for available options.
Step 4: Meet the application deadline. For cars you already own, the application deadline is typically the same as the tax payment deadline (usually the end of May). If you miss the deadline, some prefectures allow late applications but may only reduce the tax from the following month. For newly purchased cars, the deadline is usually within 30 days of registration. Check your prefecture’s specific deadlines.
Step 5: Reapply annually (in some prefectures). In some prefectures, the reduction continues automatically as long as your disability handbook is valid. In others, you must reapply every year. Check with your tax office whether your reduction is automatically continued (jidou keizoku / 自動継続) or requires annual reapplication.
Automobile Tax vs. Light Vehicle Tax
Japan has two separate vehicle taxes depending on the size of the vehicle:
- Jidousha zei shubetsu wari (自動車税種別割): The annual automobile tax for regular-size vehicles. This is a prefectural tax. Apply at the prefectural tax office or automobile tax office.
- Kei jidousha zei (軽自動車税): The annual tax for light vehicles (kei cars). This is a municipal tax. Apply at your city or ward office.
You can only receive the reduction on one vehicle. If you receive the light vehicle tax reduction from your municipality, you cannot also receive the automobile tax reduction from the prefecture on a different car.
What Happens When You Change Cars or Move?
Changing cars: If you sell or dispose of the car that has the tax reduction, you can apply the reduction to a new car. In some prefectures, you must wait until the next fiscal year if the previous car was transferred (name change) rather than disposed of. Check with your tax office.
Moving to a different prefecture: Since this is a prefectural program, if you move to a different prefecture, you need to reapply under the new prefecture’s rules. The eligibility criteria may be different. Update your vehicle registration at the local transport bureau (unyu shikyoku / 運輸支局) and then apply for the tax reduction at your new prefectural tax office.
Practical Tips
- Check your prefecture’s page first. The eligibility table for disability categories and grades is different in every prefecture. Do not assume that what applies in one prefecture applies in another.
- The disability category matters, not just the overall grade. If you have multiple disabilities listed on your shintai shougaisha techou, each one is evaluated separately against the eligibility table. The overall grade on the front of your handbook may not tell the whole story.
- Apply before the deadline. If you miss the automobile tax payment deadline (usually end of May), you may lose the reduction for that year or only receive a partial reduction.
- You cannot receive both. If your family has both a regular car and a kei car, you must choose which one to apply the reduction to. One car per person with disability.
- For seishin techou holders, get the jiritsu shien iryou jukyuusha shou first. Many prefectures require this handbook in addition to the techou. If you do not have one, apply at your ward office welfare desk before going to the tax office.
- Ask whether it continues automatically. Some prefectures require annual reapplication. Others continue the reduction automatically as long as nothing changes. Knowing this prevents accidentally losing the benefit.
- The tax office staff can help. If you are unsure whether you qualify, bring your disability handbook to the prefectural tax office and ask. They can check the eligibility table for you on the spot.
