Shiroi Koibito White by Ishiya is a signature Japanese confection built around a classic langue de chat biscuit paired with a layer of white chocolate. Each piece consists of two thin, buttery biscuits sandwiching a smooth, precisely shaped slab of white chocolate developed specifically for this product in Hokkaido.

The texture is light and crisp, yet delicate, melting quickly in the mouth due to the high butter content and controlled baking process. Its flavor profile is subtle and balanced, combining mild sweetness with creamy dairy notes, without strong or artificial flavors.

The ingredient list remains relatively simple, typically including butter, sugar, egg whites, and flour, which places emphasis on technique and ingredient quality. The 24-piece format features individually wrapped biscuits, ensuring freshness and making it suitable for sharing or gifting.

The packaging, often decorated with imagery of Mount Rishiri, reinforces its origin and identity as a representative souvenir from Hokkaido. Introduced in 1976, Shiroi Koibito has become one of Japan’s most recognizable confectionery products, reflecting a blend of European inspiration and Japanese precision in both taste and presentation.
