After a typhoon approaches or passes through, various troubles can occur: rainwater seeping through windows and flooding your floor, window glass breaking from strong winds, or water backing up from drain outlets causing flooding. In rental properties, dealing with damage can be complicated, and it's often unclear who to contact or who should bear the costs. Let's organize the steps from when damage occurs to filing an insurance claim.

Three Essential Actions Immediately After Damage Occurs

When you experience damage from a typhoon or heavy rain, your actions in the first 24 to 48 hours are crucial.

Before beginning any repairs or cleaning, be sure to document the damage with photos and videos. Take wide-angle shots of the entire room, and also capture close-ups of damaged areas. This evidence will be crucial when filing insurance claims or negotiating with your landlord.

1. Document Evidence with Photos and Videos

2. Contact Your Property Management Company or Landlord Immediately Damage caused by structural issues with the property (such as the roof, exterior walls, or shared facilities) falls under the landlord's repair obligations. If you delay reporting, there's a risk the landlord may decide the tenant wasn't aware and defer repairs. In addition to calling, document your report in writing (email or management app) to create a record.

3. Take Steps to Prevent Further Damage If a window is broken, temporarily seal it with plastic sheeting or cardboard. If there's flooding, remove water with towels or cloths. Take these emergency measures promptly. The costs of these temporary repairs may be reimbursable through insurance claims.

Basic Principle: Cost Responsibility—Landlord vs. Tenant

Who pays for repairs depends on the cause of the damage.

Costs the Landlord Bears

  • •Damage to structural parts of the building, such as the roof, exterior walls, or common corridors
  • •Water infiltration due to weathering of window frames or design defects
  • •Water backing up from aging or clogged drainage systems

Costs the Tenant Covers with Insurance

  • •Damage to household contents (appliances, furniture, clothing, etc.) from rainwater blown in by wind
  • •Water damage to household contents from sudden flooding

In principle, repairs to the building itself (floors, ceilings, walls) are the landlord's responsibility, while damage to household contents is typically covered by household contents insurance (fire insurance) that tenants purchase.

How to File a Household Contents Insurance (Fire Insurance) Claim

Fire insurance policies that you're typically required to purchase when renting often include coverage for household contents damage from typhoons, flooding, and wind damage.

Verify What Your Coverage Includes Check your insurance certificate or your insurance company's member portal to confirm that your policy includes coverage for "wind damage," "water damage," and "flooding." While wind damage is covered by most policies, flooding (including rising water and floor-level inundation) may require an additional rider, so be sure to check.

Filing Process

  1. Report the incident to your insurance company's call center or via their online claim form
  2. Prepare a list documenting the date of damage, the situation, and all damaged items
  3. Submit photos, videos, repair estimates (or proof of purchase for appliances)
  4. The insurance company's claims adjuster will either conduct an on-site inspection or review the documents (depending on the claim)
  5. Once the payout amount is determined, it will be transferred to your designated bank account

Note that damage to appliances and furniture is usually calculated at "current market value" rather than the original purchase price. If your policy includes a "replacement cost" or "replacement value" rider, you'll receive a payout closer to the original purchase price.

Key Points for Negotiating with Your Property Management Company

If water leaks or flooding caused by the building's structural problems (such as roof cracks or aged window frames) damage your floors or walls, the landlord is responsible for repairs. However, in practice, some landlords may refuse payment citing "insufficient evidence" or "unclear causation."

Prepare to Negotiate Effectively

  • •Retain photos taken immediately after the damage and copies of your communications with the management company (including email timestamps)
  • •Ask repair contractors to identify the source of the problem in writing
  • •A professional inspection report (such as a water leak diagnosis) will strengthen your negotiating position

If discussions stall, you can also contact your prefecture's real estate industry association or the National Association for Real Estate Transaction Appropriate Promotion (RETIO) for mediation assistance.

Preparation Before Typhoon Season

It's more important to prevent damage through advance preparation than to deal with it after the fact.

  • •Clean Your Drains: Clogged drainage outlets on balconies or common corridors can cause water to back up and flood during heavy rain
  • •Check Window Locks: Make sure windows are secure and won't open in strong winds
  • •Relocate Valuables and Appliances: Move floor-level appliances and valuables to shelves or higher locations before typhoon season
  • •Review Your Insurance Coverage: Check your policy before typhoon season and add coverage if needed

Advance preparation and prompt action make the difference between minor and major damage when typhoons and heavy rains occur. Even as a renter, take responsibility for protecting your own belongings by being proactive about insurance coverage and learning effective negotiation techniques.
