After purchasing, you just need to show the QR code directly. This time, we chose Okayama Castle (the parfait exchanged on the 1st floor was really delicious, and the hot dog we paid extra for was also super tasty), the Lumiere cafe at Hotel Granvia, and Bic Camera to use the pass, and my family was very happy. I suggest listing the usable attractions on the page, which would be more convenient. The pass can also be used at various small shops in Kurashiki, but we didn't use it this time because we were too full from lunch.
