I spotted a cheesecake-flavored KitKat at a local drugstore and decided to pick it up. The product is the “KitKat Blueberry Cheesecake Flavor Mt. Fuji Pack (10 Pieces).”
Upon tasting it, I found several unique characteristics that set it apart from conventional KitKat varieties.
A KitKat Designed Specifically as a Japanese Souvenir
This is a distinctive product called the “Mt. Fuji Pack,” and as you can see, the box is crafted in the shape of a mountain. Printed on the front of the packaging is a slice of rare cheesecake topped with blueberry sauce, alongside iconic Japanese heritage landmarks such as Osaka Castle and a five-story pagoda. Having a rare cheesecake illustrated side-by-side with Mt. Fuji and traditional Japanese architecture is truly unprecedented.
The Mt. Fuji-shaped box and imaginative illustration clearly signal that this product is geared toward tourists. In fact, the store shelf featured promotional signs in Chinese, and the price was set at 1,296 yen, which firmly places it in the souvenir price tier (standard 10-piece KitKat bags typically sell for around 400 yen at Japanese supermarkets). While I bought this one as part of my ongoing research into cheesecake-flavored sweets, buying it purely for personal consumption definitely requires a bit of courage.
KitKat is well known as an immensely popular souvenir among international tourists visiting Japan, primarily because Japan offers a vastly wider variety of exclusive regional and seasonal flavors compared to other countries. This quirky Mt. Fuji pack was undoubtedly created to cater to that strong demand from inbound travelers.
Let’s take a look inside. The box contains 10 individually wrapped KitKat bars neatly packed inside.
The individual wrappers feature illustrations of Mt. Fuji and cherry blossom petals, giving them a charming, quintessential Japanese souvenir feel.
An Ultra-Rare Blue-Colored Cheesecake Sweet
Unwrapping the bar reveals a striking and unusual two-tone appearance featuring white and vivid blue.
This color scheme is inspired by Mt. Fuji (which is traditionally depicted in blue and white in Japanese illustrations). While I have tasted various cheesecake- and cheese-flavored KitKats over the years, this is the very first time I’ve encountered one using blue coloring. Looking into it, blue KitKat releases are exceptionally scarce across the entire brand history.
Countless cheesecake-flavored snacks—such as chocolate pies and rice crackers—hit store shelves in Japan every year, but I have never seen any other product utilizing blue. In that sense, it stands out as an exceptionally rare cheesecake treat.
Blueberry Cheesecake-Flavored Chocolate with Cheese Powder-Infused Wafers
In terms of structure, the outer chocolate coating is infused with blueberry cheesecake flavor, while the crispy wafers inside sandwich a smooth cream blended with cheese powder.
Tasting Impressions
Now, let’s dive into the tasting review. The texture is classic KitKat—delivering a light, crisp, and crunchy bite with the perfect harmony of chocolate and wafer layers.
As for the flavor, it turned out slightly different from what I had imagined. Alongside the milky sweetness typical of white chocolate, you clearly taste notes of blueberry and unbaked rare cheesecake. Beyond that, a subtle, unexpected refreshing sensation gently spreads across the palate—a unique cooling note not found in previous cheesecake KitKats or other cheesecake sweets.
While it is certainly not an unpleasant flavor, that very first bite will likely catch you by surprise. It might be a bit polarizing depending on personal preference, but if you are curious about novelty snacks, it is definitely worth checking out!
