Japanese Christmas cake are traditionally made for what type of filling?

Japanese Christmas cakes are traditionally made with a light, fluffy sponge cake filled with whipped cream and adorned with strawberries. The cake is often layered with fresh fruit and decorated in a festive manner, making it a popular treat during the holiday season. This combination of cream and strawberries gives the cake a fresh and celebratory flavor, distinct from Western-style fruitcakes.
