A large plastic jar of "iriko," small dried anchovies. It's the sort of stuff I used to feed my pet turtles (when I had pet turtles). But for some Japanese it's a snack food. Sitting in front of the TV dipping your hand into the dried fish jar and eating it like Canadians might eat popcorn or potato chips. I think it's gross ... but it's probably quite healthy.
It’s probably a very common snack throughout Asia recognize. I know that Singaporeans call it "ikan bilis," and eat it either by itself or mixed with peanuts and chili sauce, and with "nasi lemak," coconut-flavoured rice. Japanese eat them as well mixed with other things - nuts at an alternative dry snack, or mixed within a bowl of hot rice for dinner.
A bag of "niboshi" in a Co-op supermarket. "niboshi" are a little larger than "iriko." Also, "iriko" are salty, but "niboshi" are not.
