Is Earthquake Insurance Necessary for Rental Apartments? Understanding the Difference from Fire Insurance and Key Points for Enrollment

Japan is one of the world's most earthquake-prone countries. Major earthquakes occur repeatedly—the 2011 Great East Japan Earthquake, the 2016 Kumamoto Earthquakes, the 2024 Noto Peninsula Earthquake—and for renters, the question "Is earthquake insurance necessary?" is extremely important.

To put it simply, earthquake insurance serves a different role for renters than for homeowners. Since the building is owned by the landlord, tenants need only protect their personal belongings. However, losses to belongings can easily reach hundreds of thousands to millions of yen, and without coverage, rebuilding life can become difficult. It's essential to first understand the differences between fire and earthquake insurance, then determine what coverage you personally need.

Fire Insurance vs. Earthquake Insurance: Fundamental Differences in Coverage

Fire insurance (tenant liability insurance), required at nearly all rental sign-ups, and earthquake insurance cover entirely different types of disasters.

Fire insurance (tenant liability) covers damage from fire, water leaks, lightning strikes, wind, and snow. It includes landlord compensation for damages you cause due to negligence (tenant liability), as well as coverage for your personal belongings (property coverage). This is the insurance effectively required by rental contracts.

Earthquake insurance specifically covers damage caused by earthquakes, volcanic eruptions, and tsunamis triggered by earthquakes. Critically, most fire insurance policies include an "earthquake hazard exclusion clause," meaning fires directly caused by earthquakes (earthquake-triggered fires) and building collapse are not covered by fire insurance at all.

During the 2011 Great East Japan Earthquake, massive fires after the quake destroyed many belongings, yet tenants with only fire insurance received no compensation. This is a critical lesson when considering whether earthquake insurance is necessary.

What Earthquake Insurance Does and Doesn't Cover for Renters

Earthquake insurance available to renters covers only personal belongings. Since the building is owned by the landlord, tenants cannot purchase earthquake insurance for the building itself.

Examples of Personal Belongings Covered

• •Furniture (sofas, beds, kitchen cabinets, dressers, etc.)
• •Appliances (TVs, refrigerators, washing machines, computers, etc.)
• •Clothing, daily necessities, and books
• •Valuables (cash and securities have partial limits)

What Is Not Covered

• •The building itself (wall cracks, roof damage, structural collapse, etc.) → covered by landlord's insurance
• •Automobiles (covered by automotive insurance earthquake/volcanic eruption/tsunami special clauses)
• •Theft losses occurring after the earthquake

However, if your belongings are destroyed by fire triggered by an earthquake, you can receive compensation from your earthquake insurance. Earthquake insurance covers not only the initial earthquake but also secondary damage resulting from it—such as tsunamis and fires—which is a key feature of this coverage.

Insurance Premium Estimates and How to Set Coverage Amounts

Earthquake insurance cannot be purchased alone; it must be bundled with fire insurance. Coverage amounts are set between 30–50% of your fire insurance coverage for personal belongings, with a maximum limit of 10 million yen.

Premiums are determined by "building structure (wood, steel, or reinforced concrete)" and "local earthquake risk (based on prefecture classification)." As a general guideline, for a one-person household in Tokyo with 5 million yen in personal belongings coverage, annual earthquake insurance premiums are roughly 10,000–30,000 yen. In higher-risk areas like Shizuoka Prefecture, premiums are correspondingly higher.

Insurance payouts are made in four tiers: total loss (100%), major loss (60%), partial loss (30%), and minor loss (5%). Since minor loss (damage of 3–20% of coverage) pays only 5%, it's important to position earthquake insurance as coverage for major disasters rather than minor damage.

To estimate your belongings' total value, list the purchase prices of major appliances and furniture. Even for a single person, total belongings often reach 2–3 million yen.

Regions and Situations Where Earthquake Insurance Is Especially Important

We especially recommend earthquake insurance in the following cases:

High earthquake-risk regions: According to the government's "National Earthquake Hazard Assessment Map" published by the Earthquake Research Promotion Bureau, the Kanto, Tokai, Kinki, Shikoku, and Pacific-facing regions of Kyushu—where Tokyo-area earthquakes and Nankai Trough megaquakes pose high risks—are classified as high-risk. Check your area's risk level before deciding whether to enroll.

If you own expensive belongings: High-end appliances, pianos, stringed instruments, camera equipment, and collectibles can represent significant economic loss in an earthquake. For particularly valuable items, consider additional coverage through special clauses.

For long-term residents or families: If you plan to stay long-term or have accumulated significant household goods, insurance is worthwhile protection. Conversely, for temporary assignments, weigh it against your total belongings value.

Enrollment Procedures and Choosing an Insurance Company

Here's how renters enroll in earthquake insurance:

At sign-up: When receiving fire insurance information from your real estate agent or insurance broker during move-in, simply request earthquake insurance be added. You can also add it to existing fire insurance later.

Choosing an insurer: You're free to choose any company, not just those recommended by your agent. Because earthquake insurance coverage is standardized by law (the Earthquake Insurance Law), all insurers offer identical coverage and rates. However, fire insurance terms and discounts vary, so compare quotes from multiple companies.

Discount programs: Many insurers offer "seismic discount" (up to 50% off) based on building seismic performance, as well as discounts for longer contract terms. If your building has a confirmed seismic grade, check whether you qualify.

Earthquake Preparedness Goes Beyond Insurance

Earthquake insurance is important, but true disaster preparedness combines it with physical preparation. Here are practical steps renters can take:

• •Prevent furniture toppling: Install anti-tip struts or mats on bookshelves, refrigerators, and kitchen cabinets. Many products available for rental apartments don't damage walls.
• •Prepare an emergency kit: Assemble three days' worth of food, drinking water, first aid supplies, a portable charger, and copies of important documents in one place.
• •Know evacuation locations and routes: Familiarize yourself with your nearest designated shelter and multiple evacuation routes in advance.
• •Check hazard maps: Use the Ministry of Land, Infrastructure, Transport and Tourism's "Hazard Map Portal" to assess earthquake, flood, and landslide risks in your area.

While considering earthquake insurance, combine it with these physical preparations to create a secure rental living environment. Adopt the mindset "I protect my own assets," and start preparing today so you won't panic when disaster strikes.
