Mochinyan Summer Festival' will be held at the 2nd-floor event space of Seibu Shibuya Store's Building A, where the 'Imperial Concubine Lychee Cake' — a collaboration between Mochinyan, a popular character from Taiwan, and KAISHII (KAISHII), a Taiwanese confectionery manufacturer celebrating its 100th anniversary in 2027 — will be sold as a limited-edition item in special Mochinyan packaging.

Reimagining the fruit beloved by Yang Guifei for modern tastes Lychee, one of Taiwan's representative fruits, has long been known as 'the fruit beloved by Yang Guifei' in ancient tales.

The 'Imperial Concubine Lychee Cake' generously features Taiwanese lychee, prized for its fragrant aroma and juicy sweetness. While based on the traditional pineapple cake-making method, it highlights lychee's floral fragrance and elegant sweetness, elevating it into a new-generation dessert that stands apart from conventional pineapple cakes — a refined treat designed for adults.

It pairs excellently with black tea or Taiwanese oolong tea, making it a perfect centerpiece for a special tea time.

Savor the rich aroma of Taiwanese tea

KAISHII, driven by the desire to share Taiwan's rich food culture with more people, focused on lychee — one of Taiwan's iconic fruits.

The 'Imperial Concubine Lychee Cake' is a new product born from the fusion of KAISHII's century-old confectionery craftsmanship, which has preserved Taiwan's traditional sweet-making culture, and Mochinyan's vision of becoming 'a bridge between Japan and Taiwan.'

Furthermore, in line with our desire for 'more customers to casually enjoy KAISHII's signature flavors,' we will offer both the limited-edition package and individual units for sale.
