'Shiroi Black Thunder' was launched as a Hokkaido souvenir in 2011. By 2021, it had surpassed a cumulative total of 200 million units shipped*1, growing to become a new staple souvenir from Hokkaido over its 15-year history. Currently, it is available in various sizes and is cherished as a souvenir that is easy to share with many people.

To commemorate this milestone, we are launching a product renewal that evolves its taste, along with several commemorative initiatives unique to Hokkaido. These plans are infused with our desire for 'Shiroi Black Thunder' to be remembered as 'the go-to souvenir from Hokkaido' and to continue to be enjoyed by many people.

This product has been renewed to enhance the rich milk flavor and strengthen the characteristic 'crunchy' texture of Black Thunder. Furthermore, we will be livening up the anniversary through special initiatives unique to the 15th year, including the launch of limited-edition menu items in collaboration with 'Parfait, Coffee, Sake, Sato', a parfait specialty store originating in Sapporo, and decorated trains that can only be seen in Hokkaido.

We hope you will enjoy this product, which allows you to feel the special and limited nature unique to Hokkaido, not only as a souvenir for yourself but also as a gift for loved ones such as family, friends, and those you are indebted to.

'Shiroi Black Thunder' Product and Packaging Renewed!

Since its launch, 'Shiroi Black Thunder' has been manufactured at Yuraku Confectionery's Sapporo factory and has been loved by many as a Hokkaido-exclusive product that combines Hokkaido ingredients with the taste of Black Thunder. This time, on the occasion of its 15th anniversary, we are implementing a product renewal to pursue a special taste unique to 'Black Thunder x Hokkaido'.

The renewed product features an enhanced milk flavor by not only using Hokkaido milk in the coating chocolate but also by incorporating a newly developed milk-flavored biscuit that spreads a gentle sweetness, specifically for this product.

Additionally, the characteristic 'crunchy' texture of Black Thunder has been strengthened. By newly incorporating harder cocoa cookies in addition to the conventional ones, the crunchy texture is further enhanced, and the satisfying bite has also been improved.

With the rich milk flavor and strengthened texture, we have created a powered-up 'Shiroi Black Thunder' that allows you to better enjoy the appeal of Hokkaido ingredients and the unique texture of Black Thunder.
