I bought both of these today. I tried a bite of each too... in the name of research. The one above is a "Yuzu and Spice", according to the cashier where I bought it. It has a little bite... much like Chili Pepper Kit Kats. Not bad.
These are the Okinawa and Kyushu special edition. This flavor is beni imo, or sweet potato. They are perfect for an area where sweet potatoes abound.
