I was offered DCC at a tourist-heavy knife shop in Japan this week, but the offer was made on the payment screen and the clerk said "you want to be charged in yen, right?" as soon as the interface showed up. A quick nod and she touched the Japanese flag and the receipt generated in JPY and the charge posted in JPY.

It displayed a Japanese flag and a US flag and the prices in each. The DCC markup was about 3% over the Visa rate for the day.

I had rarely encountered DCC in Japan, and I guess still have, but had gone for several weeks without seeing it at all until this knife shop.
