They're pretty common streetfood in Japan. Batter, a piece of octopus, maybe some green onion, a bit of ginger, topped with katsuo (dried, shaved, bonito flakes), Japanese mayonnaise and a savory sauce. Personally I skip the mayo, but they're delicious! You do have to be careful not to eat them too soon, because they're really hot!

And wow to his skill and speed!
