Experience Authentic "Fuwa Shuwa" Texture in Ebina with Taiwanese Castella Made from High-Quality Japanese Ingredients - Expect Long Lines!

BOC Japan LLC (Headquarters: Minato-ku, Tokyo; Representative: Tomohiko Komatsu), which operates franchise development for Taiwanese food stores, will open a three-day limited pop-up store for its Taiwanese castella specialty store "Tairaku Tangaō" at the "Taiwanese Night Market Festival in Ebina," held at the Ebina Station West Exit Central Plaza from April 3rd to April 5th, 2026.

On March 12, 2021, amidst the COVID-19 pandemic, "Tairaku Tangaō" opened in Tokyu Plaza Ginza. On its first day, it created a massive line that stretched to the Tokyo Metro Ginza Station, becoming a rare piece of bright news. Since the opening of the Tokyu Plaza Ginza store, we have received tremendous support from our customers, and the number of repeat customers continues to grow. It has been featured in numerous media outlets, including NTV's "ZIP," "Hirunandesu," and "130 Million People's SHOW Channel," Fuji TV's "Mezamashi TV," BS Asahi's "Teiban Times," and has been covered in the Yomiuri and Sankei newspapers, women's magazines like "GINGER" and "Hanako," and travel guidebooks.

At this pop-up store, we will be selling our popular Taiwanese castella, which adopts the traditional Taiwanese manufacturing process to replicate the local taste and texture. The lineup will include the plain flavor, the featured Burnt Butter Vanilla Sugar, a Half & Half set with a choice of three flavors including chocolate and Earl Grey, single-serving cut castellas, and the new-texture castella pudding.

The Popular Taiwanese Castella That Draws Long Lines

Taiwanese castella is a home-style sweet that has long been cherished in Taiwan, known as "現烤蛋糕 (xiàn kǎo dàngāo)," meaning "freshly baked cake." It is served in large slices and its fluffy texture and subtle sweetness make it perfect not just as a snack, but also for breakfast.

Repeat Customers Hooked on the Authentic Taiwanese "Fuwaa Shuaa" Texture

"Tairaku Tangaō's" Taiwanese castella is characterized by its soufflé-like "fuwaa shuaa" (fluffy and moist) texture, achieved by using fresh egg yolks, milk, and carefully selected flour, mixed with a meringue made from egg whites, and then slowly baked. The combination of the moist cake, and the flavors of egg and milk, fills your mouth with a happy taste. Despite its generous, handful-of-a-size, its melt-in-your-mouth texture keeps you coming back for more, making it a mysterious castella that has turned many first-timers into repeat customers.

For product development, a specialized staff trained in Taiwan came to Japan to faithfully reproduce the local taste and texture using the authentic Taiwanese method. This is a truly genuine Taiwanese castella. By using the authentic method with high-quality Japanese ingredients, it can be described as a meticulously crafted, premium Taiwanese castella. We hope you will feel like you're traveling by tasting the authentic Taiwanese castella from Tairaku Tangaō.
