Snapper yaki is correct.

Snapper yaki is made by pouring a mixture of wheat flour, sugar, and baking soda into a metal mold made in the shape of a snapper, adding a pinto bean filling to it, and then adding the ingredients to the other half of the mold as well, sandwiched between the pinto bean filling, and baking it. Snapper yaki is one of Japan's unique sweets eaten along with Japanese sencha, an inexpensive confection.

Origin

It is said that snapper yaki originated in the Meiji era. In 1909, Naniwa Ka, a confectionery store in Azabujuban, Tokyo, borrowed the "tai" part of the word medetai (meaning "sea bream") and put the ingredients into a sea bream-shaped mold to make a confection, and this is the origin of sea bream yaki. The meaning of "medetai" is "good luck and good things", and because of its interesting shape, it quickly became a topic of conversation, and became popular as a new confectionary, gradually spreading throughout Japan.
