Marusei Butter Sand Blueberry by Rokkatei is a limited item that feels quite different from the original.
Rokkatei is one of the most famous confectionery companies in Hokkaido, and Marusei Butter Sand is a very popular souvenir.
I was curious and decided to try the blueberry version, and honestly, I really liked it.
Here is my honest review.
Requires Refrigeration & Very Short Shelf Life

One of the most notable differences is that this blueberry version needs to be kept refrigerated and has a very short shelf life—sometimes only until the same day.
Because of this, it is something you can only enjoy locally in Hokkaido.
Lighter Than the Original Butter Sand
The original Marusei Butter Sand is quite rich, but this blueberry version is much lighter.
It was easier to eat and not too heavy.
Real Blueberry Flavor

The blueberry flavor really stands out.
It doesn’t feel like just an added twist—it feels like the main feature.
The sweetness is well balanced and not overwhelming.
Crispy Cookie Texture
The cookie was crispy, which added a nice texture.
Overall, it felt lighter than the original version.
Texture Changes Over Time
After some time, the cookie becomes softer and slightly moist.
It is still enjoyable, but I recommend eating it while it is fresh and crispy.
Final Thoughts
Rather than being just a variation of the original, this feels like a completely different dessert.
• Light and easy to eat
• Great for blueberry lovers
• Only available locally in Hokkaido
• Very short shelf life, so timing matters
If you see it at a store, it is definitely worth trying.
Where to Buy Marusei Butter Sand
The blueberry version is only available in stores in Hokkaido and cannot be ordered online.
However, the original Marusei Butter Sand is available online.
