Japan Property Insurance Companies: A Complete Comparison for Foreigners

Buying property in Japan is a major milestone — but protecting that investment requires understanding a complex insurance landscape that can be challenging for foreigners. From fire insurance mandated by lenders to government-regulated earthquake coverage, Japan's property insurance system operates differently from what most expats are used to. This guide compares the major providers, explains what you need, and helps you choose the right policy as a foreign property owner or renter in Japan.

Understanding Japan's Property Insurance System

Japan's property insurance system is divided into two main types: fire insurance (kasai hoken) and earthquake insurance (jishin hoken). Understanding how they work together is essential before comparing providers.

Fire insurance covers a wide range of risks including:

• Fire, lightning, and explosions
• Typhoons, windstorms, and hail
• Floods and water damage (burst pipes)
• Theft and vandalism
• Falling objects

Notably, fire insurance does NOT cover earthquakes, volcanic eruptions, or tsunamis. For that, you need earthquake insurance — but here's the key rule: earthquake insurance can only be purchased as an add-on to fire insurance, never as a standalone policy. Coverage is capped at 30–50% of your fire insurance amount.

Another crucial point for comparison shoppers: earthquake insurance premiums are government-regulated by the Financial Services Agency (FSA) and managed through the Japan Earthquake Reinsurance Company (JER). This means the earthquake insurance portion costs the same regardless of which company you buy from — only fire insurance premiums vary between providers.

While fire insurance is not legally mandatory in Japan, virtually all mortgage lenders require it as a loan condition. Most landlords also require renters to have fire insurance before signing a lease, so in practice, it's nearly unavoidable.

Major Japan Property Insurance Companies for Foreigners

Here's a comparison of the main insurance providers available to foreign residents and property owners in Japan:

Chubb Insurance Japan

Chubb is one of the most foreigner-friendly property insurers in Japan. As a global insurer with a dedicated Tokyo office, Chubb offers English-language support throughout the application, policy management, and claims process. Their coverage tends to be broader and more flexible than domestic Japanese insurers, making them popular with non-resident owners and high-net-worth expats. Contact: 03-6364-7000.

AIG Japan

AIG has long been a go-to insurer for international residents in Japan. They offer multilingual support and comprehensive property coverage that can be tailored to the needs of foreigners. AIG is well-suited to expats working for international companies who want seamless coverage that aligns with their home-country insurance experience.

Tokio Marine Nichido

Japan's largest and oldest insurance company, Tokio Marine Nichido offers strong coverage at competitive rates. While their primary service language is Japanese, many experienced real estate brokers and bilingual agents can help foreigners navigate the application process. Their extensive domestic network makes claims processing smooth in Japan.

Sompo Japan

Sompo Japan (part of Sompo Holdings) has a strong international network and is particularly notable for being willing to insure properties for non-resident foreign owners — a category that many domestic insurers refuse to cover. If you're buying Japanese property as an overseas investment without living there, Sompo Japan is worth prioritizing.

TRINITY Inc.

For foreigners who want full English support from a specialized broker, TRINITY Inc. is one of the best options in Japan. They handle fire insurance, property insurance, and casualty coverage with a fully English-speaking team. This is especially valuable given that most insurance documents in Japan are Japanese-only, which can lead to foreigners choosing suboptimal plans without realizing it.

Kyosai (Cooperative Insurance)

Kyosai are non-profit mutual aid cooperatives that offer significantly lower premiums than commercial insurers. Options include Zenkyoren (agricultural co-op), CO-OP Kyosai, and various labor union cooperatives. The trade-off is more limited coverage and customer service that's almost entirely in Japanese. Best suited for long-term permanent residents with strong Japanese language skills or Japanese-speaking support.

Property Insurance Costs in Japan: What to Expect

Understanding typical costs helps you evaluate quotes and choose the right coverage level.

Fire Insurance Costs

• Apartments (concrete/T-structure): ¥10,000–¥20,000 per year
• Houses (wooden/H-structure): ¥30,000–¥100,000+ per year
• Tokyo 70m² condo (5-year policy): ¥4,450–¥39,200 per year depending on coverage options

Wooden structures cost significantly more to insure than concrete buildings. A 100m² wooden house in a rural area might cost ¥35,000–¥55,000 per year, while a 60m² concrete apartment in Tokyo might cost ¥20,000–¥30,000 annually.

Tip: Longer policy terms (5–10 years) typically offer 15–20% savings compared to annual renewals, but you pay upfront. Many buyers purchase multi-year policies at the time of purchase.

Earthquake Insurance Costs

• Annual earthquake insurance: ¥6,500–¥32,600 per year
• 2-year combined policy: approximately ¥5,000–¥20,000 for the earthquake portion

Remember: earthquake insurance premiums are government-set and identical across all providers, so you can't shop around on price for this component.

What Affects Your Premium

What Does Japan Property Insurance Cover?

Standard Fire Insurance Coverage

Earthquake Insurance Payout Levels

Earthquake insurance payouts in Japan are standardized:

Note: Earthquake insurance coverage is capped at 30–50% of your fire insurance amount. So if you have ¥20 million in fire coverage, your earthquake coverage can be at most ¥10 million.

How to Apply for Property Insurance as a Foreigner

Eligibility Requirements

To apply for property insurance in Japan as a foreign national, you generally need:

• Valid residence card (Zairyu Card) or special permanent resident certificate
• Japanese bank account for premium payment
• Domestic phone number (for most providers)
• Property details: address, building type, year of construction, floor area
• Japan-based emergency contact (some providers)

Non-residents purchasing Japanese property as an investment face more restrictions. Sompo Japan and Chubb are among the more accommodating options for overseas buyers.

The Application Process

1. Gather property information — building structure, age, floor area, replacement value
2. Request quotes from multiple providers (use a bilingual broker for best results)
3. Compare fire insurance options (earthquake insurance costs are fixed)
4. Submit application with residence card and property documents
5. Pay premium via Japanese bank account or credit card
6. Receive policy documents (in Japanese — request English summaries if available)

Tips for Foreigners Navigating Japan's Insurance Market

Use a Bilingual Broker The language barrier is the single biggest challenge for foreigners buying insurance in Japan. Most policy documents, renewal notices, and claims forms are in Japanese only. Working with a bilingual insurance broker (or a specialist like TRINITY Inc.) dramatically reduces the risk of misunderstanding your coverage. This is well-documented at resources like Living in Nihon and other expat guides.

Don't Just Take the Real Estate Agent's Recommendation Many real estate agents in Japan have affiliated insurance providers and may steer you toward their preferred insurer. While convenient, this may not offer the best value. Always get independent quotes. For additional perspective on the home-buying process and what to watch out for, For Work in Japan provides useful context on navigating Japan's real estate ecosystem as a foreigner.

Consider Whether You Need Non-Resident Coverage If you're buying Japanese property without residing there, standard residential insurance may not apply. Check with providers like Sompo Japan or Chubb about non-resident property insurance options. For more on the financial and practical considerations of property decisions as a foreigner, see Gaijin Buy House's article on selling vs. renting property when leaving Japan.

Check Employer Coverage First Many international companies and some Japanese employers provide basic property or contents coverage for expat employees. Check what your employer's policy covers before purchasing additional insurance.

Factor In Earthquake Insurance Seriously Japan is one of the world's most seismically active countries, experiencing over 1,500 earthquakes per year. Despite this, only about one-third of Japanese households hold earthquake insurance. Given the potential for devastating earthquakes in major cities — Tokyo, Osaka, Nagoya — earthquake insurance is strongly advisable for property owners.
