For our trip to Japan, my wife and I picked up this card since it had a 0% interest rate, and didn't charge foreign transaction fees. Both of these were appealing since we needed to buy plane tickets from foreign carriers, train tickets, food, hotels etc. The costs alone were expensive but no sense on paying extra fees.
It worked well for the most part, but it was getting denied at way too many places like restaurants and some convenience stores, so we either had to use some of our cash or our personal VISA cards which was not convenient. I would say it was getting denied ~7-10% of the time.
