If that were the reason, then mainland China wouldn't do so with the prevalence of Union Pay cards.

This would be likely the case.
But I doubt as in any other country, the cashier would be trained and understand that it'll cost more to charge in home currency than in JPY. So by the book they will explain it, but probably to only お客様、日本円とドル、決済はどちらがいいでしょうか？ (Sir, madam, would you like to be charged in JPY or USD?) and will offer a choice, but that's about it. They'll not go into the detail about DCC which they have no understanding of.
