Taiyaki: a fish-shaped sweet

たい焼き

Taiyaki is a filled cake baked in a sea-bream-shaped mould. The familiar version has a wheat-flour shell and sweet red-bean filling: the fish is its shape, not its meat.

What is inside the fish?

Shell, filling and shape

A thin shell encloses the filling. Naniwaya, a long-established Tokyo shop, makes its batter from flour and water; other recipes differ. Custard, sweet potato and chocolate are among the alternatives to red-bean paste. Ingredients such as milk and eggs depend on the recipe.

Head first or tail first?

Either is fine. There is no national rule about where to start, nor a requirement that every tail contain filling. A freshly baked cake can be broken in half and left briefly before eating; whether its shell is thin and crisp or soft and substantial depends on the maker.

02

How the mould makes the cake

Batter is added over red-bean filling in a fish-shaped mould.

Batter and filling go between two faces

The maker puts batter and filling into a metal fish mould, closes the matching faces and heats the cake. The mould shapes both surfaces while the shell cooks around the filling. Pouring, turning and heating routines vary between makers.

Multi-cavity plate

One fish at a time—or several

An itchō-yaki iron has a pair of hinged mould faces for one cake. A multi-cavity plate bakes several fish together. The playful labels tennen, “wild,” and yōshoku, “farmed,” refer to these arrangements. They do not describe the ingredients or provide an official quality grade.

From round cakes to fish

A relative of imagawayaki

Taiyaki is a fish-shaped relative of imagawayaki, round cakes with a filling. Origin accounts connect the sea-bream shape with good fortune: tai echoes medetai, meaning auspicious or celebratory. The exact beginnings remain disputed.

A shop founded in 1909

Naniwaya was founded in 1909 and figures prominently in accounts of taiyaki’s beginnings, although its founder is not an uncontested sole inventor. The shop’s fourth-generation proprietor describes a large prewar network, contraction around the war and a move from Kudan to Azabu-jūban around 1948.

Izumi Kyōka mentions taiyaki alongside imagawayaki in his street-market story Hoshimise (露肆). The passage places the sweet among the foods sold by night-stall vendors.

The fish that swam into popular culture

“Oyoge! Taiyaki-kun” appeared on the television programme Hirake! Ponkikki in 1975, and the single was released that December. Sung by Masato Shimon, it turned a fish-shaped cake into a familiar animated character. The recording came decades after the food had become established.

Changing the shell, filling and format

Chewy white cakes and flaky pastry

Some white taiyaki use tapioca flour for a chewy texture. Croissant-style versions use layered dough instead of the usual batter; Ginnoan describes its product as having 24 layers. These are different approaches to the shell, not simply different fillings.

A mould can change the animal

Aquamarine Fukushima’s Gombe-yaki uses the shape of a coelacanth and is sold with chocolate, cream or red-bean filling. A different mould gives this local version its distinctive shape and name.

Beyond a freshly cooked shop snack

Taiyaki also travels as a frozen product. Commercial versions may be thawed or reheated in different ways; follow that product’s instructions. A frozen supermarket cake and a freshly baked shop cake share a recognisable form without necessarily sharing the same recipe or texture.

Related fish-shaped sweets abroad

Bungeoppang in Korea

South Korea’s Culture Portal traces bungeoppang to the arrival of Japanese taiyaki in the 1930s, during colonial rule. Its name refers to a crucian carp rather than a sea bream. It developed into a familiar Korean street snack with its own name and variations.

What can you now explain?

Does taiyaki usually contain fish?

No. Tai refers to the sea-bream shape. The familiar filling is sweet red-bean paste.

What makes the scales and fins?

The shaped surfaces of the metal mould.

What does itchō-yaki mean here?

Baking a single fish-shaped cake in one hinged iron.

Are “wild” cakes an official higher grade?

No. “Wild” and “farmed” are informal labels for single-mould and multi-cavity production.

What does the year 1909 securely establish?

Naniwaya’s foundation. It does not by itself prove an uncontested invention date for all taiyaki.

Did the 1975 song introduce the food?

No. The food was already established; the song gave it a popular fictional character.

How can white taiyaki differ from the familiar version?

Some use tapioca flour to make a chewy shell; recipes and fillings vary.

How is bungeoppang related?

Korean cultural sources trace it to the introduction of taiyaki in colonial Korea in the 1930s; its name refers to crucian carp.

Must you start at the head?

No. Head-first and tail-first are preferences, not a national eating rule.
