As a follow up, we saw our first point of sale instance of DCC at KITTE Marunouchi when Mrs. Majuki was making a purchase at one of the stores. The terminal displayed a prompt on the LCD with clear instructions of what to do to decline DCC. The cashier also presented a quote slip, similar to what I've seen in Taiwan and Singapore. I also saw the quote slip at the transit hotel that The Royal Park Hotel operates at Haneda about 5 years ago. The pending transaction amount shows the non-DCC rate, and Mrs. Majuki double checked to make sure that she was signing a receipt denominated in JPY.
