Aoyama Decarbo's First Store Opens at Isetan Shinjuku
Aoyama Decarbo will open its first store in Isetan Shinjuku. Business will begin on Wednesday, May 20, 2026.
This store has been meticulously designed down to the finest details of the sales floor to create a space where you can enjoy shopping while experiencing the worldview of Aoyama Decarbo. We will provide an unprecedented new experience that fuses sweets and miscellaneous goods. At the storefront, we will roll out introductions to new products and seasonal projects, allowing you to enjoy new discoveries every time you visit.
Furthermore, we plan to set up an interactive corner where you can touch upon the story of how Aoyama Decarbo's sweet tins are born and the charm of their unique designs.
We will aim to create a store where all visiting customers can enjoy the unique worldview of Aoyama Decarbo.
The Isetan Shinjuku Exclusive 'Cat's Playing Cards Can' is Isetan-colored everywhere
The "Cat's Playing Cards Can," which has been well-received and is currently on its second release.
We will newly release the 'Cat's Playing Cards Can' with a design exclusive to the Isetan Shinjuku store.
Speaking of Isetan, the MacMillan pattern is familiar even from its paper bags. We designed MacMillan-patterned playing cards on the side of the tin. The background color of the crown design on the lid is inspired by the color of the handles on Isetan's paper bags.
The illustrations on the playing cards are glass paintings of fashionable cat princesses.
The highlight is that they are holding Isetan paper bags. With Isetan paper bags in hand, the cat princesses are enjoying their shopping.
On the bottom exterior of the tin, a glass painting of a cat Joker dressed in a peacock gown is placed. The Joker also holds an Isetan paper bag aloft, seemingly enjoying shopping.
On the inside bottom of the tin, we have applied a glass painting inspired by the 'Peacock,' which is the symbol of Isetan and is also depicted on the relief at the front entrance of the Isetan Shinjuku Main Building. This is a hidden detail that Isetan fans must see.
Choose your favorite 'Cat's Jewel' at the store
The bonus item for the Isetan Shinjuku exclusive "Cat's Playing Cards Can" is one of 8 types of "Cat's Jewels." We have newly created miniature cat decorations that sparkle like jewels specifically for this project.
These very small cat figures are made of flocky material. The height is surprisingly about 2cm.
We adorned these small figures with accessories such as crowns and necklaces to express a jewel-like brilliance.
We were particular about finishing the figures to be as small and delicate as possible, repeatedly making prototypes until we were satisfied, resulting in these figures we are proud of.
If you place it gently on the palm of your hand and gaze at it, it's a heart-fluttering bonus item like a tiny jewel.
You can choose your favorite one from all 8 types at the storefront. Please find your favorite one. We prepare them with a red accessory case.
To commemorate the store opening, we will present a crown design charm
To commemorate the opening of the Aoyama Decarbo store, we will present a crown charm to customers who purchase 3,300 yen or more including tax at the store.
Since quantities are limited, this will end as soon as they run out.
Contains Gluten-Free 'Gianduja White Chocolate'
The sweets inside the Isetan Shinjuku exclusive 'Cat's Playing Cards Can' are 'Gianduja White Chocolates.' Made with Aoyama Decarbo's original low-carb chocolate, we finished it as a healthy sweet.
Generously using rich hazelnut paste with crispy rice flour flakes.
It is a highly satisfying chocolate that makes you forget it's gluten-free.
Once you taste it, you will surely be surprised by the deliciousness that doesn't seem like a healthy sweet.
Planning to launch an accessory storage case to enjoy even after the sweets are gone
To ensure you can enjoy the tin even after eating the sweets, we are also planning to launch a dedicated case where you can store accessories.
* The release date is undecided.
