Castella (カステラ) is a sponge cake introduced to Nagasaki by Portuguese merchants in the 16th century. The Japanese version evolved into a distinct form: denser than European sponge cake, sweeter, and with a characteristic golden-brown top and bottom crust.

Nagasaki has 30+ castella makers, each claiming recipe variations. The standard presentation is a long rectangular cake sold in wooden boxes — traditionally given as formal gifts. Eating fresh castella from the actual bakery, where the cake is still warm from the oven, is a completely different experience from the packaged gift version.

Insider Guide

Premium

**Fresh vs aged:** Fresh castella (within 3 hours of baking) has a slightly crispy crust and warm, moist interior — fundamentally different from the next-day product. Fukusaya bakes every 2 hours; time your visit for post-baking (ask staff for 'yaki-tate jikan' / baking schedule). **Castella tasting comparison:** Three major brands within walking distance: Fukusaya (original, classic), Bunmeido (slightly sweeter), and Shooken (matcha and chocolate varieties). Buy a slice from each café for ¥300-400 and compare — the sweetness levels and texture differences are significant. **The 'bottom paper' tradition:** Castella is baked with paper lining the bottom, which remains attached when sold. You're meant to eat it with the paper (it's edible rice paper), though most first-time buyers try to remove it. The paper is part of the intended texture.
