Japan has a pretty much variety of fish and seafood snacks; they are so handy that anyone can get a packet from a nearby convenient store.

This product available at a 7-Eleven, named "Almond Fish," contains dried young anchovies cooked in sweetened soy sauce and mixed with crushed roast almonds. The light texture of almond flakes and rich flavors of anchovies will become a good company of you as an option of healthy snacking.
 

The other one is from MUJI, dried and freshly packed full-body capelins. Most of the Japanese people love eating female capelines bearing eggs. Also, male capelines are known for the deeper flavor.

If you are a fish-lover and happen to visit Japan again, try them out.
