This flavor has been recycled many times since Nestle Japan started selling limited edition KitKats, but this might be the first time I've tried it. Salted caramels were quite trendy a few years ago, and even though the sweets industry has mostly moved on, the combination is still good.
The packaging feels a little nautical, and I like that. My bar was a little melted, since it came from Japan in the summer (and I'm just getting around to it, yikes), but it still had its structural integrity, so I doubt the flavor was affected.
The chocolate had a strong caramel scent with just a hint of salt. When I bit into it, it was apparent that the wafers were very salty and that the caramel flavor seemed to come from the chocolate. The two tastes came together nicely for a savory flavor.
I do enjoy the ratio of wafer to chocolate in the larger KitKat, especially when the flavors are done well. The salt mostly kept the sweetness of the milk chocolate in check, and the bar easily defeated my craving for salty/sweet.
