Takoyaki (たこ焼き, lit. „grilled octopus“) are a popular kind of street food which you come across around nearly every corner in large Japanese cities, especially in the Kansai region (Ōsaka, Kyōto, …).
These came from the Tenjinbashi-suji in Ōsaka.
Edit: correct translation
Mate, if you write Kyōto, you also have to write Ōsaka
While we’re being pedantic,
It doesn’t literally mean that, it’s more like “grilled octopus”.
You‘re both right! Thanks for pointing that out, edited post for correctness.
