Is this a UCC question?
under UCC article two,this is about the merchantability.As the seller (the japanese company) is a merchant,it has a implied warranty of merchantability.Restate it,the machine should be able to deal with the task that CE faced.If the seller violate the warranty,the buyer can give a notification to the seller seasonably and stored the machine.Any commercially reasonable expenses related to the seller's violation of the warranty and commercial losses can be covered and CE can seek a remedy under UCC or CISG.
If the two parties write a provision about which law will be applied to the contract and some details about the implied warranty in order to make an expressed warranty in the contract,the buyer will be able to remedy the loss easier.
