BUNNMEIDOU Castella (also known as Kasutera or Nagasaki Sponge Cake)
Castella (カステラ, kasutera) is a type of Japanese sponge cake and is known for its sweet, moist brioche-style flavour and texture. It is based on cakes introduced to Japan by Portuguese merchants in the 16th century. It was then popularized in the city of Nagasaki, where it is considered a specialty. Despite its foreign origins, it is considered a kind of wagashi, or traditional Japanese confectionery.
Crafted with a perfectly balanced, light sweetness and baked to fluffy perfection by skilled artisans, this classic honey sponge cake embodies BUNNMEIDOU’s dedication to tradition and quality. Enjoy its soft, airy texture and refined flavor—an iconic taste of Japanese confectionery craftsmanship.

Nagasaki-Origin Castella
A hallmark of Nagasaki-style Castella lies in the layer of coarse sugar crystals at the bottom.
Over time, these crystals gently melt, enhancing the cake’s moist texture and adding depth to its flavor.
Please note: due to temperature and storage conditions, the sugar crystals may partially dissolve before consumption.
