This little fish is a taiyaki, or “sea bream cake”, a street food that is popular with hungry people of all ages in Japan.
Taiyaki are usually filled with a sweet, smooth bean paste made from dark red azuki beans. If you closely at the photo of this hashioki you may see a bit of bean paste escaping from the fish’s body beneath its’ jaw. I like azuki bean filling, but my favorite taiyaki filling is yellow sweet potato — not quite as sweet as azuki beans, but still delicious.
Taiyaki are made by pouring a pancake-like batter into heated metal molds. It’s fun to stand outside a taiyaki shop in a shopping arcade or at a festival and see dozens of taiyaki, baking in their molds, and swimming like a school of fish towards all the hungry customers.
