This terminal DCCs (compliantly).
I made a split payment - on my HK-issued HKD-denominated card, choice between JPY and HKD was offered (and I was able to select the former).

But when I put in Wirex card (issued by Wirecard Pte in Singapore), no DCC is offered and it goes straight to JPY charging.
DCC doesn't work on a multi-currency card (a good reason to get one if yes!)?
