Senshuan Confectionery Co., Ltd. (Headquarters: Sapporo, Hokkaido; President and CEO: Katsuhiko Nakanishi) is refreshing the packaging of its beloved northern buche pastry 'White Night,' first launched in 1970, to better reflect Hokkaido's identity and appeal to a wider range of generations. Additionally, a new flavor, 'White Night Rum Raisin,' will be newly launched. Enjoy the newly enhanced 'White Night,' preserving its cherished taste while adding fresh appeal.

What is the Northern Buche 'White Night'?

'White Night' has been a long-selling favorite from Sapporo Senshuan since its 1970 launch. A type of Western confection known as 'buche,' it features cream or jam sandwiched between light, fluffy baked layers, known for its delicate texture. The essential cake base uses a unique, time-honored method perfected over decades, achieving a crisp exterior and a soft, airy interior. The name 'White Night (WHITE NIGHT)' refers to the natural phenomenon in high-latitude regions during summer, where the sky never fully darkens at night. Hokkaido's summer, with its earlier dawns compared to Honshu, sees the sky brightening from early morning between June and July. The 'White Night' buche captures this uniquely northern summer scene—bathed in soft light—through its fluffy texture and gentle flavor. Now, a new flavor variant, 'White Night Rum Raisin,' is being introduced.

NEW <White Night Rum Raisin>

This version sandwiches butter cream with rum-soaked raisins into the fluffy cake. Enjoy a sophisticated flavor where the rich aroma of rum harmonizes with the smooth, mellow taste of butter cream.

About the Renewed Packaging

'White Night' is a buche that evokes the image of the actual white night phenomenon through its soft, gentle flavor. The 1970s sensibility of the original release is reinterpreted in a modern way. The 'White night' logo revives the original design by Ken'ichi Kurutani, known as the father of Hokkaido's graphic design. The illustration inherits the original 1970s package composition while being modernized. A delicate gradient representing the white night sky beautifully depicts the short yet stunning summer scenery of northern Japan.
