Japanese convenience stores, commonly known as “conbini,” are places where you can always find something new. This time, some particularly exciting news has just broken.
The world-renowned premium ice cream brand, Häagen-Dazs, is releasing a special flavor available exclusively at 7-Eleven stores in Japan. Its name is the “Häagen-Dazs Spécialité Japonais Wa-Kocha Butter Cream Cake.”
This special ice cream will be released sequentially in limited quantities starting from Tuesday, December 2, 2025, at 7-Eleven stores nationwide in Japan. Let’s take a closer look at the experience this fusion of Japanese conbini culture and luxury sweets has to offer.
The ‘Japonais’ Series: A Special Collection Highlighting Japanese Ingredients

“Japonais” is a special series developed by Häagen-Dazs Japan, created with respect for Japan’s food culture and ingredients. Based on the concept of “a next-level reward ice cream dessert,” it uses carefully selected Japanese ingredients to express a complex and rich flavor profile, much like a dessert from a specialty shop.
This series is often sold exclusively at Japanese convenience stores, and each time a new flavor is released, it becomes a hot topic. It could be said to be a symbol of how Japanese conbini are not just convenient shops, but also places that launch the latest trends and exclusive products.
The Star of the Show: Rare ‘Wa-Kocha’ (Japanese Black Tea)
The star this time is “Wa-Kocha.” This is a type of black tea produced in Japan, which may still be a somewhat rare presence in a country strongly associated with green tea.

For this product in particular, it uses carefully selected ‘hatsu-tsumi ichiban-cha,’ which consists only of the first-picked new shoots harvested at the beginning of the year. The Wa-Kocha made from these tea leaves has little astringency and is characterized by its gorgeous and delicate aroma.
When you open the cup, the rich aroma of the Wa-Kocha ice cream and milk tea sauce immediately greets you. With the first bite, its elegant flavor will fill your mouth, and you are sure to feel the meticulous craftsmanship of Japan.
A Harmony of Multiple Layers, Just Like a Cake

Another feature of this ice cream is its complex layered structure. This isn’t just a simple Wa-Kocha flavored ice cream; it is designed to represent a complete dessert: a ‘Wa-Kocha butter cream cake’.
On top is a milk tea (Wa-Kocha) sauce adorned with sparkling silver powder sugar (sugar coated in silver powder). Beneath that is the Wa-Kocha ice cream, where you can directly enjoy its aroma. As you dig deeper, you’ll find a rich butter ice cream with butter cookies mixed in for a textural accent.
While each layer has its own unique character, together they create an exquisite harmony, like a single butter cream cake. The change in flavors as you eat your way through the layers is truly a sublime dessert experience.

The ‘Gohoubi’ (Reward) Experience, Reflected in the Design
In Japan, there is a culture of “gohoubi” (a reward), which involves buying a slightly luxurious sweet as a small gift to oneself for hard work. This product is the perfect item for just such a moment.
The packaging features a chic design inspired by classic tea tins. The sparkling silver powder sugar on top that you see the moment you open the lid helps to create a special moment. This dedication to a “premium feel” in every detail builds anticipation before you even take your first bite.
