Earthquake Insurance for Foreign Residents in Earthquake-Prone Japan: A Rational Assessment of Necessity and Cost
Coverage scope of earthquake insurance, actual payout examples from major past earthquakes, regional insurance rate differences, and cases where you should—or shouldn't—get coverage, explained with foreign residents' actual living situations in mind.
Before deciding on earthquake insurance, you need to grasp Japan's earthquake risk with objective figures. According to Japan Meteorological Agency statistics, Japan experiences approximately 60 earthquakes of magnitude 4.0 or greater per year on average, around 8 earthquakes of magnitude 5.0 or greater annually, and 5 to 10 earthquakes of magnitude 6.0 or greater per decade. This frequency is overwhelmingly higher than other major developed nations worldwide.
Reviewing major earthquakes causing residential damage over the past 30 years—the Great Hanshin-Awaji Earthquake (1995), the Niigata Chuetsu Earthquake (2004), the Great East Japan Earthquake (2011), the Kumamoto Earthquakes (2016), the Hokkaido Eastern Iburi Earthquake (2018), and the Noto Peninsula Earthquake (2024)—damage of a scale that changes individuals' lives has occurred roughly once every five years.
Many foreign residents have never experienced earthquakes in their home countries and believe "it won't happen to me in Japan." However, government agencies have announced that the probability of a Tokyo Metropolitan earthquake and Nankai Trough earthquake occurring within the next 30 years exceeds 70%. For residents of major cities like Tokyo, Osaka, Nagoya, Fukuoka, and Sendai, it is realistic to view earthquakes as a risk you will "definitely experience someday."
Earthquake Insurance Covers Damage Not Covered by Fire Insurance
A crucial feature of Japan's insurance system is that damage caused by earthquakes is not covered by fire insurance. Even if you have fire insurance, damage from earthquake-triggered fires, tsunami damage, and building collapse or household goods destruction caused by earthquakes will not be compensated at all unless you have separate earthquake insurance.
This is the point that confuses foreign residents most easily. In some countries, home insurance includes earthquake damage as standard, so many people move in assuming "I have fire insurance so earthquake damage is covered too."
Earthquake insurance can only be purchased as a package with fire insurance, and the coverage ceiling for earthquake insurance is 30–50% of your fire insurance's household goods compensation amount. For example, if you have fire insurance with 2 million yen in household goods coverage and add earthquake insurance at 50% of that amount, your household goods damage from earthquakes would be compensated up to a maximum of 1 million yen.
Earthquake Insurance Rates Vary Significantly by Region and Building Type
Because earthquake insurance is based on a government reinsurance system, there is little difference in insurance premiums among insurance companies. Rates are determined by prefecture and building type, with annual insurance premiums per 1 million yen in household goods coverage ranging as follows:
High earthquake risk areas (Tokyo, Kanagawa, Chiba, Shizuoka, Ibaraki, Tokushima, Kochi): approximately ¥8,000–¥12,000 annually for wooden apartment buildings; ¥4,000–¥6,000 for reinforced concrete apartments.
Moderate earthquake risk areas (Osaka, Aichi, Fukuoka, Miyagi, Pacific coast of Hokkaido): approximately ¥4,000–¥7,000 annually for wooden buildings; ¥2,000–¥3,500 for reinforced concrete.
Low earthquake risk areas (Aomori, Akita, Yamagata, Niigata, Shimane, Tottori, Sea of Japan coast of Hokkaido): approximately ¥2,500–¥4,500 annually for wooden buildings; ¥1,300–¥2,300 for reinforced concrete.
Discount programs include: building age discount (10% for buildings constructed after 1981 meeting new seismic standards), seismic grade discount (10–50%), and seismic isolation building discount (50%). For apartments, you can obtain certificates of construction year and seismic grade by inquiring with the building management association.
Cases Where You Should—or Shouldn't—Get Coverage
The cost-effectiveness of earthquake insurance depends on your total household goods assets, expected length of stay, and your residential area's risk level. There is no blanket rule that everyone should get it, so consider the following criteria:
Strongly recommended cases: ① Planning to live in a high earthquake risk area (Tokyo Metropolitan area, Tokai, Shikoku, Miyagi) for one year or longer; ② Total household goods assets exceed 1 million yen (with furniture, appliances, musical instruments, PC equipment, and clothing); ③ Household with children where early restoration of the living foundation including infant supplies and educational materials is important; ④ Cases with special coverage that includes temporary lodging fees and evacuation rent after earthquakes.
Cases worth considering carefully: ① Planning to stay in a low earthquake risk area for less than one year; ② Minimal household goods with only the rental property's furnishings; ③ Alternative housing secured in case of disaster (such as student or company dormitories); ④ Plan to save the insurance premium amount and self-insure instead.
Earthquake Insurance Payouts Are Tiered by Damage Level: Partial, Half, or Total Loss
Earthquake insurance payouts are structured so that the insurance payment amount is determined by the damage assessment level. For household goods, partial loss (10–30% of total household goods damage) receives 5% of the household goods insurance amount; minor half-loss (30–60%) receives 30%; major half-loss (60–80%) receives 60%; and total loss (80% or more) receives 100%.
This tiering is not intuitive to foreign residents, so many mistakenly assume "I have earthquake insurance for 1 million yen in household goods, so I'll get 1 million yen." In reality, if earthquake damage to your household goods is assessed as partial loss, you receive only ¥50,000; you only receive the full 1 million yen if it is deemed total loss.
In the Great Hanshin-Awaji Earthquake, average payouts to insured households centered on ¥200,000–¥800,000 (20–80% of household goods insurance amounts). Even in cases other than complete total loss, replacing furniture and appliances, paying for temporary lodging during evacuation, and repurchasing clothing and tableware can cost tens of thousands of yen, so the insurance can significantly accelerate your recovery.
Getting Coverage, Claiming After Disaster, and Assessing Your Risk Tolerance
You can apply for earthquake insurance at the same time as fire insurance. You can also add it mid-term: simply contact your current fire insurance company and say "I want to add earthquake insurance"—they will calculate the premium for the remaining period and add it as a special provision. After an earthquake, the typical process for filing a claim involves taking photos of the damage, creating a list of damaged items, and a site survey by the insurance company. In major earthquakes, insurance adjusters may be overwhelmed, so payouts can take months. It's wise to store your fire and earthquake insurance policy numbers and emergency contact information in multiple places—with family, at work, and on your smartphone.
For foreign residents, you may also need to contact your embassy immediately after an earthquake to confirm your residency status. In parallel with filing your earthquake insurance claim, also register with your home country's embassy emergency contact network, keep copies of your residence card, and pre-arrange communication methods with family and friends (LINE, WhatsApp, Signal, etc.) as part of your disaster preparedness.
Earthquake insurance is a form of pure protection: you pay the premium regardless of whether an earthquake occurs. But that's the nature of insurance—it's a mechanism to avoid catastrophic unexpected loss, and its cost is not something to begrudge when nothing happens. As a foreign resident, it's important to assess your personal risk tolerance across three dimensions: your future outlook in Japan, the cost of rebuilding your household goods, and the financial burden if you need to evacuate to your home country. At an additional annual cost of around ¥10,000–¥20,000 combined with fire insurance, earthquake insurance offers a way to accelerate your recovery after a disaster. Consider it as one realistic safety net for living securely in Japan, an earthquake-prone nation.
