“A golden sponge cake with centuries of Portuguese-Japanese heritage.”
A moist, golden sponge cake — somewhere between pound cake and angel food cake — with a thin layer of crunchy sugar crystals on the bottom. Brought by Portuguese traders 400 years ago and shaped by Japanese bakers over centuries into a distinctly Japanese treat.

The Inside Scoop
Did you know?
It's officially classified as a Japanese sweet, not Western — not just because it's been here for 400+ years, but because Japanese bakers transformed it so thoroughly (adding mizuame syrup, zarame sugar crystals) that it became a distinctly Japanese creation. The Portuguese original (pão de Castela) had a drier texture — a different take that evolved into something entirely its own.
How to eat
- 1Look for the thin, crunchy sugar layer on the bottom — that's the 'zarame' and it's the best part. Don't peel it off!
- 2Eat it at room temperature for the best texture — the moistness really comes through.
- 3Pairs wonderfully with milk or green tea. The Nagasaki original (Bunmeido or Fukusaya brands) is worth seeking out.
