Origin Story

Castella originated in 16th-century Japan, introduced by Portuguese missionaries and traders during the Nanban trade period. Its name derives from the Portuguese term "Pão de Castela," meaning "bread from Castile," reflecting its Iberian roots. Over time, Castella was adapted to Japanese tastes and became a celebrated specialty of Nagasaki, symbolizing the region’s historical openness to foreign influences.

Classification

Castella belongs to the sponge cake family, characterized by a batter leavened primarily through air incorporation rather than chemical agents or fats. Unlike butter cakes, Castella contains no added fat, relying on whipped eggs and starch syrup to achieve its moist, tender crumb.
