Earthquake insurance is purchased as an add-on (rider) to fire insurance and covers damage caused by earthquakes, volcanic eruptions, and tsunamis.

Do you think "Since I'm renting, earthquake insurance is the landlord's responsibility"? Actually, landlords insure the building, but your household items receive zero coverage. This guide explains the necessity and mechanics of household earthquake insurance (typically ¥500–¥1,500/month) with real-world examples of what happens without it.
A clear explanation of fire and home contents insurance coverage required for rental housing. We'll detail the differences from landlord-specified insurance, the benefits of choosing your own policy, the necessity of riders for water damage, theft, and tenant liability coverage, and expert tips on keeping premiums affordable.
Important Point: Standard fire insurance does not cover fires caused by earthquakes. Without earthquake insurance or an "earthquake fire coverage rider," damage to personal belongings from post-earthquake fires may not be covered.
Annual Premium Guide: For earthquake insurance covering ¥3 million in personal property, annual premiums in Tokyo (highest earthquake risk zone) are approximately ¥5,000–¥8,000. In Sendai, Osaka, Nagoya, and similar areas, they are typically ¥3,000–¥5,000 per year.
Insurance Payout Conditions (Damage Categories):
A disaster certificate (disaster damage certificate) is an official document certifying the extent of damage caused by a disaster (earthquakes, fires, floods, etc.). It is required for earthquake insurance claims and applications for various forms of public assistance (disaster relief funds, housing support).
Steps to Obtain a Disaster Certificate:
Note for Foreign Residents: Applications at municipal offices are typically conducted in Japanese. English and multilingual support vary by municipality. During large-scale disasters, multilingual support centers are set up in various locations and can be used for assistance.
Required Documents:
Example scenario: ¥3 million in personal property coverage, residing in central Tokyo (23 wards), with annual premiums of ¥6,000:
Insurance premiums over 10 years: ¥60,000 Insurance payout if minor partial loss occurs: ¥3,000,000 × 30% = ¥900,000
At ¥6,000 per year, a single major earthquake provides substantial coverage. However, for minor damage (partial loss at 5%), the payout would be ¥150,000, which is less compelling in terms of cost-benefit.
Earthquake insurance is strongly recommended if you live in expected impact zones for the Nankai Trough or Tokyo Metropolitan Area earthquakes, such as Tokyo, Yokohama, Osaka, or Kobe. The Sendai and Tohoku regions also carry high risk in light of the 2011 Great East Japan Earthquake.
