I recommend you try 2 types of Japanese popular cheap and unique snacks.
REKKA-WASABI 烈火わさび
Try this wasabi snack when you visit Japan!
It is dangerously super hot wasabi flavor!
This product is called REKKA-WASABI 烈火わさび (Price: about 180 yen), and it is a type of Japanese Okaki おかき snack, which are finger foods that are usually made from sticky rice that is baked or deep-fried.
The specialty of this snack is dangerously super hot wasabi flavor!
Usually, wasabi snacks don't really have strong flavor, but this strong wasabi flavor will kick your nose, however it surely is quite addictive. This is the best choice if you love wasabi.
It is a great souvenir and you can use it to prank or punish others.
The manufacture is a small scale company, thus, it is quite difficult to find it at stores - general supermarkets and convenience stores.
Fortunately, I did manage to find it at a shop specializing in snacks around Ueno 上野 area of Tokyo.
Check out this shop below. Grab them before they are out of stock!
