Beano is also perhaps the world's most entertaining Japanese snack food in that it is wasabi-powder covered pieces of baked soy bean paste. Not only is Beano spicy (in the special wasabi way), salty, and crunchy: it also causes extremely violent gas. If you do not understand why this may be, I urge you to look over the primary ingrediants again: wasabi & soy beans. This does make this snack food the anti-American version of Beano, which is a food additive that is supposed to suppress gas.
