Experience the Exquisite Story of Mampei Hotel's New Cookie Sandwich

Introducing the 'Cassis & Blueberry Sandwich'

Mampei Hotel, located in Karuizawa, Nagano Prefecture, under the management of Ichiro Sasaki, is thrilled to announce the launch of its first cookie sandwich from the 'Storytelling Cookie Sandwich Series.' Starting February 2, 2026, customers will be treated to the 'Cassis & Blueberry Sandwich,' available both in-store and online.

Following the favorable reception of the 'Walnut Bitter Caramel Sandwich' released in August 2025, this newly launched series encapsulates the unique charm of Mampei Hotel. The 'Cassis & Blueberry Sandwich' is inspired by the hotel’s popular cafe terrace menu item, the blueberry tart, featuring a buttery cookie sandwiching a cream rich in blueberry and cassis flavor. With a focus on fresh blueberries and a balance of sweet and tart notes, this delightful treat offers a vibrant taste experience.

The packaging design is reminiscent of the elegance associated with glamorous lady guests at Mampei Hotel, showcasing iconic motifs such as the hotel's original sign, claw-foot bathtubs, and signature treats like apple pie and royal milk tea. Each element on the package tells a part of the hotel's storied history, adding to the experience of enjoying this unique dessert.

Imagine indulging in a tea time filled with the fresh and fruity aromas reminiscent of Karuizawa’s refreshing air, all while savoring the luxurious feel of the hotel atmosphere.
