The amount of damages in the event of loss of or damage to goods is determined by the market price of the goods (or by quotations on an exchange, for goods for which this is applicable) at the place and time at which the goods are to be delivered; provided, however, that if there is no market price, this is determined by the normal price of goods of the same type and with the same quality at that place and time.
運送品の滅失又は損傷の場合における損害賠償の額は、その引渡しがされるべき地及び時における運送品の市場価格（取引所の相場がある物品については、その相場）によって定める。ただし、市場価格がないときは、その地及び時における同種類で同一の品質の物品の正常な価格によって定める。
Costs, including freight charges that are no longer payable due to the loss or damage to goods, are deducted from the amount of compensation for loss or damage referred to in the preceding paragraph.
運送品の滅失又は損傷のために支払うことを要しなくなった運送賃その他の費用は、前項の損害賠償の額から控除する。
The provisions of the preceding two paragraphs do not apply if the loss or damage to goods arises at the carrier's intention or due to the carrier's gross negligence.

損害賠償
Compensation for loss one person has caused another. A debtor who does not perform an obligation as it should be performed, or cannot perform it, must compensate the creditor for the loss that results, unless the failure comes from a cause the debtor is not responsible for, judged by the contract or other source of the obligation and by accepted views in dealings (Civil Code, Article 415, paragraph (1)); and a person who, intentionally or negligently, infringes another's rights or legally protected interests must compensate for the loss that results (Article 709). It is paid in money unless otherwise agreed (Articles 417 and 722, paragraph (1)), and the parties to a contract may agree in advance the amount due if it is not performed; a sum fixed for breach (違約金) is presumed to be such an agreement (Article 420, paragraphs (1) and (3)). The Consumer Contract Act makes void the part of such an amount in a consumer contract, for its cancellation, with any penalty added, above the average loss the business would suffer from the cancellation of consumer contracts of that kind, measured separately for each category the clause sets, such as the reason for and time of cancellation (Consumer Contract Act, Article 9, paragraph (1), item (i)).
