From October 28 to November 3, 2025, the Taiwanese castella specialty store "Tairaku tangao" will open a limited-time pop-up at Tokyo Metro Ikebukuro Station's Echika Ikebukuro "SWEETS BOX."
This pop-up event features the popular plain Taiwanese castella made with authentic Taiwanese methods, along with the signature burnt butter vanilla sugar flavor, cheese, Earl Grey, and a total of 6 varieties in half-and-half sets. The lineup also includes bite-sized cut castella and the innovative castella pudding with a unique texture.
What Makes Tairaku tangao's Taiwanese Castella Special
Tairaku tangao's Taiwanese castella features a distinctive "fluffy and moist" texture, made generously with fresh egg yolks, milk, and carefully selected flour, mixed with meringue made from egg whites and slowly baked like a soufflé cake. The combination of moist castella texture with the aroma of eggs and milk fills your mouth with happiness. Despite its large size that overflows in both hands, it has a melt-in-your-mouth quality that keeps you eating without getting tired—a mysterious castella that turns first-time customers into repeat buyers.
For product development, specialized staff who trained in Taiwan came to Japan and faithfully recreated the authentic Taiwanese methods and textures. Using traditional Taiwanese techniques with high-quality Japanese ingredients, it can be called a premium Taiwanese castella. Experience the authentic taste of Taiwan with Tairaku tangao's genuine Taiwanese castella.
