A Unique Collaboration for Nighttime Indulgence

Experience a new culinary delight as the tart specialist AM STRAM GRAM joins forces with the record bar BANTEN to present an exclusive line of butter sandwiches designed for the evening enjoyment of adults. Set to launch on August 17, 2025, this collaboration offers decadent treats featuring seasonal fruits and high-quality ingredients, embodying the essence of Japanese flavors.

The Inspiration Behind the Creation

The collaboration originated from a casual conversation at BANTEN’s counter, highlighting the desire for sweet treats during late-night hours. This idea blossomed into a unique partnership where AM STRAM GRAM’s expertise in fine ingredient selection and layering techniques merged with BANTEN’s appreciation for the harmonious interplay of sound and Japanese culture. The resulting butter sandwiches are a refined representation of flavors intended specifically for after-dark enjoyment.

Product Features

Unlike typical butter creams used in conventional butter sandwiches, these treats showcase a luxurious blend of custard and buttercream known as Crème Mousseline, crafted specifically for tarts. The base is a special sugar dough made by AM STRAM GRAM, stamped with a design of “Tai” (a type of fish) to give these desserts an exclusive touch.

Flavor Lineup

1. Rum Raisin: A classic pairing that accentuates the allure of Crème Mousseline, this flavor stands as the quintessential choice for adults.

2. Matcha & Black Beans: This unique combination of bitter-sweet Matcha from Nishio and the sweetness of domestically produced black beans creates a taste reminiscent of traditional Japanese desserts.

3. Strawberry: Bursting with flavor, this delightful sandwich incorporates luxurious freeze-dried strawberry powder and dried strawberries for a fruity burst in every bite.

Purchase Information

Starting from August 17, 2025, these exclusive butter sandwiches will be available at BANTEN, along with A10 and A9. Priced at ¥770 (tax included) for a single piece or ¥2,200 (tax included) for a set of three, these gourmet snacks promise an unforgettable treat tailored for late-night cravings.

Indulge in a unique combination of music, drinks, and these exquisite butter sandwiches. Embrace the “sweet experience of the night” known only to adults.
