“21-ji ni Ice,” a popular specialty shop for ice cream enjoyed at night, known as “Yoru Ice,” has launched its first-ever collaboration with 7-Eleven in Japan. The featured collaboration products are two types of parfait ice creams that recreate the shop’s popular flavors: “21-ji ni Ice Choco Banana” and “21-ji ni Ice Murasaki Imo (Purple Sweet Potato) Mont Blanc.”
These special parfaits will be released sequentially in limited quantities starting from Tuesday, December 23, 2025, at 7-Eleven stores in the Tokyo metropolitan area and the Kansai region. This is your chance to easily enjoy the taste of the specialty shop, which has been trending on social media, right from the comfort of your own home.
What is the “Night Ice” Culture Booming in Japan?
To understand this collaboration, it’s essential to know about the food culture trend that has emerged in Japan in recent years: “Yoru Ice” (Night Ice) or “Shime Parfait” (Finishing Parfait). This refers to the custom of ending the day, perhaps after dinner or a few drinks, with a slightly rich dessert.
The spark that ignited this boom can be attributed to “21-ji ni Ice,” which opened its first store in Osaka in 2020. As its name suggests, it is an ice cream specialty shop focusing on the evening hours and has become so popular that it now boasts over 40 locations across Japan. Its menu, featuring a base of soft-serve ice cream with a clean aftertaste combined with a wide array of toppings, has captivated many people. This collaboration can be described as a groundbreaking initiative, allowing customers to experience the taste of this popular specialty shop at a Konbini, one of the most accessible places for everyone.

This is a treat that captures the classic combination of “choco banana,” a favorite loved by all generations.
The parfait features a two-layer structure of refreshing milk ice cream and rich chocolate ice cream. A banana sauce with a satisfying pulpy texture and a decadent chocolate sauce are exquisitely swirled throughout. For an added textural accent, two kinds of toppings and a layer of crushed cookies at the bottom ensure you’ll enjoy it to the very last bite. It’s a must-try parfait for chocolate lovers, faithfully recreating the taste of the specialty shop’s popular menu item.

The other flavor features “Murasaki Imo” (purple sweet potato), a popular autumn taste in Japan. As the name suggests, murasaki imo is a sweet potato with a vibrant purple color and is known for its elegant sweetness.
In this parfait, a beautifully piped purple sweet potato cream on top gives it an appearance just like a Mont Blanc cake. It has a two-layer structure of refreshing milk ice cream and a flavorful purple sweet potato ice cream, all brought together by a special sauce made with a rich purple sweet potato paste. You can fully enjoy the natural, gentle sweetness and deep flavor of the ingredients.
Final Thoughts
This collaboration is a fantastic opportunity to more easily experience the new Japanese food culture of “enjoying a rich ice cream at night.” The fact that these special sweets, which previously required a trip to a specialty shop, are now available at 7-Eleven stores in Japan is welcome news for many.
Sales are limited to stores in the Tokyo metropolitan area and the Kansai region and will end once they are sold out. If you live in Japan or are visiting during this period, why not check your local 7-Eleven and experience a delightful taste that will satisfy both your stomach and your soul?
