Shiroi Black Thunder is the Hokkaido-exclusive version of Black Thunder, the popular chocolate snack bar made by Yuraku Confectionery. First introduced in 1994, Black Thunder is known for its satisfying bite and crispy texture, while Shiroi Black Thunder adds a distinctly Hokkaido twist with rich white chocolate made with Hokkaido milk.
Shiroi Black Thunder retains the characteristic crunch and satisfying texture of the original Black Thunder, but its coating is made with generous amounts of Hokkaido milk.
Browned butter oil is also used as a subtle flavoring, adding richness and a fragrant roasted note to the white chocolate. The result is a flavorful combination of creamy Hokkaido milk and cocoa biscuit that remains enjoyable from the first bite to the last.
Shiroi Black Thunder was introduced in 2011 as a Hokkaido-exclusive souvenir. Since then, related products have also been developed, making it a familiar choice for visitors looking for an easy-to-share taste of Hokkaido.
Its compact, easy-to-carry size makes it particularly convenient as a souvenir. It is available in three different package sizes, including options that are suitable for giving to several people.
Shiroi Black Thunder is produced at the Yuraku Confectionery Sapporo Factory in Sapporo, Hokkaido. With its combination of crisp cocoa biscuits, rich white chocolate and Hokkaido milk, it offers a simple and approachable way to enjoy a regional version of one of Japan’s familiar chocolate snacks.
