* Image is for illustrative purposes only.Many collectors and nihonto (日本刀) dealers who own Japanese swords believe they are "protected because we have insurance." However, a careful reading of the terms and conditions of standard moveable property comprehensive insurance or fire insurance policies reveals hidden risks: tōken (刀剣) may be classified as "weapons" and excluded from coverage, or appraisal amounts may not be recognized without a certified appraisal certificate attached.
This article provides a concrete explanation of the procedures, required documents, and key points for negotiation with insurers that sword owners actually face when using damage insurance.
There are three main types of damage insurance that can cover tōken.
Moveable property comprehensive insurance (fine art and antiques endorsement) is the most widely used. It covers unforeseen accidents — both domestic and international — such as damage, theft, fire, and water damage. Some insurers determine the coverage amount based on a declared value or assessment certificate, though if the declared amount diverges significantly from market conditions, the insurer may appoint an independent appraiser to reassess.
Fire insurance household contents endorsement can apply to tōken stored at home in some cases, but often imposes a ceiling that proves insufficient for high-value swords. Additionally, swords may be classified as "weapons" and excluded, so confirmation with the insurer before signing the contract is essential.
Transport insurance applies when tōken are relocated, shipped by mail, or transferred. Japanese swords require specialized packing even for domestic transport, and if the insurer's packing standards are not met, the claim may be denied.
In case of theft, first file a police report at your local police station and obtain the case reference number. This number is required for the insurance claim. For fire or water damage, photograph and video the damage as thoroughly as possible to document the extent of loss. Never dispose of the remains, as the insurance surveyor may need to examine them later.
Contact your insurance company promptly — typically within 30 days — to report the accident. At this stage, have the following ready:
The loss adjuster (or surveyor) appointed by the insurer will conduct a site investigation. Since most general adjusters lack expertise in tōken, the insured has the right to demand that the insurer appoint a specialist appraiser in Japanese swords. If this demand is not granted, submit an assessment report from a third-party organization (such as NBTHK or an authorized nihonto dealer) as a counterargument.
If you disagree with the compensation amount offered by the insurer, proceed to settlement negotiation. The following materials strengthen your position:
If negotiation reaches an impasse, you can utilize the Loss Insurance ADR (alternative dispute resolution mechanism). This service is free and provides neutral mediation.
Owners of particularly important or celebrated swords are advised to attach an "itemized declaration" endorsement to their policy for each piece in their collection. This practice has each sword's appraised value explicitly documented in the contract, preventing valuation disputes at the time of loss.
In standard insurance, the purchase price serves as the baseline, but the sword market fluctuates with supply and demand. Swords purchased years ago should be re-evaluated at their current market price. It is advisable to obtain a fresh appraisal from NBTHK or an authoritative dealer at least once every three to five years.
Complex issues arise if a sword is recovered after an insurance payout for theft. Most insurance policies stipulate that "if insured property for which compensation was paid is subsequently recovered, the insured may either transfer ownership of the property to the insurer or return the compensation received."
Since a tōken's ownership is tied to its registration certificate, the certificate typically remains with the victim even after theft. To reclaim a recovered sword as "your own," returning the insurance payment may be necessary in some cases. Understanding this point in advance is crucial.
Key points for sword owners to use insurance effectively:
Japanese swords are not merely property — they embody cultural heritage. By using insurance appropriately, we fulfill our responsibility to preserve their value for future generations.
