On March 12, 2021, amidst the pandemic, Tairaku Tangao opened its first major store in Tokyu Plaza Ginza. The opening day saw massive lines extending all the way to the Tokyo Metro Ginza Station, becoming a rare bright spot at the time. Since then, the store has gained immense support, with a steadily growing number of repeat customers. It has been featured extensively in the media, including TV programs like 'ZIP,' 'Hirunandesu,' '130 Million People's SHOW Channel,' 'Mezamashi TV,' and 'Teiban Times,' as well as in the Yomiuri Shimbun, Sankei Shimbun, and magazines like 'GINGER' and 'Hanako.'
In this pop-up, the store will sell its popular Taiwan Castella, which uses authentic Taiwanese methods to reproduce local flavors and textures. The lineup includes the signature 'Plain' flavor, the featured 'Burnt Butter Vanilla Sugar,' Cheese, Earl Grey, and a 'Half & Half' set featuring all six varieties. Single-serving 'Cut Castella' sizes will also be available.
**Popular Taiwan Castella with Long Lines**
Taiwan Castella is a traditional home-style sweet in Taiwan, known as 'Xian Kao Dan Gao' (freshly baked cake). These large-cut cakes feature a fluffy texture and subtle sweetness, making them perfect not only as a snack but also for breakfast.
Tairaku Tangao's version is characterized by a soufflé-like 'fuwa-shua' (fluffy and melting) texture, made by mixing plenty of fresh egg yolks and milk with airy meringue. Despite its large size, the cake melts in your mouth and is surprisingly easy to eat, leading many to become repeat customers.
For product development, specialized staff trained in Taiwan came to Japan to faithfully reproduce the local taste and texture using authentic Taiwanese methods while utilizing high-quality Japanese ingredients. The result is a premium Taiwan Castella that allows customers to experience a travel-like feeling through its authentic flavor.
