Hi @AdamGT ,
That’s a fun challenge! 
The first item on the list is indeed Japanese. It’s a bag of furikake (ふりかけ), typical dry seasoning that you sprinkle on top of your bowl of steaming rice to give it some extra taste. This one in particular has the taste of bonito, or striped tuna, called “katsuo” (かつお) in Japanese.
The way I used to use furikake is: 1) Steam some rice and separate it into portions; 2) Pour some furikake on top and give it time to absorb the heat and soften, or mix it in directly to speed the process; 3) Enjoy my seasoned rice!
However, looking at the bottom of the bag, I think this one expired in 2012, but I can’t make out the symbols to be sure if it expired then, or was produced then.
Hope that helps!
