Kaki no tane
Here’s a packet of regular-flavored Kaki-P:

There’re Kaki-P where the crackers are coated in various flavors of chocolate (milk, strawberry, cafe-au-lait, etc.), which helps offset the spiciness. There’s a wasabi-flavored Kaki-P which is pretty hot (but good with beer). There’re also the occasional sold-for-a-limited-time-only flavors. Last year there was a black-pepper-flavored one.
