"The Cult-Favorite Japanese Snack You’re Missing Out On: Black Thunder Original"
Black Thunder Review – Japanese Chocolate Snack by Yuraku
Introduction
This article reviews Black Thunder and explains its flavor, texture, ingredients, and allergen information based on the product sold in Japan.
“Lightning-level deliciousness!”
What if a snack that costs only a few dozen yen could deliver satisfaction that rivals even high-end patisserie desserts?
Selling over 200 million units annually in Japan, Black Thunder is truly a “price-destroying” monster snack and an absolute must-have in the dagashi (cheap snack) world.
Packaging
I am genuinely happy that I can finally review this snack.
This time, I will introduce the original Black Thunder, a true classic in the world of Japanese cheap snacks and a strong ally for young people.
Let’s take a closer look at its flavor, texture, ingredients, and allergen information.
Black Thunder was first created in 1994 in Toyohashi City, Aichi Prefecture by Yuraku Confectionery.
At one point, it even faced the risk of discontinuation due to poor initial sales.
However, thanks to explosive popularity in the Kyushu region and being introduced as a favorite snack of Olympic athletes, it grew into a monster product with over 200 million units sold annually.
Today, many variations with different flavors and aromas continue to be released,
making Black Thunder a truly unique presence that continues to captivate fans across Japan.
True to its catchphrase,
👉 “Lightning-level deliciousness!”
its biggest appeal is the ability to deliver intense satisfaction instantly and affordably.
Appearance
This is the Black Thunder.
At first glance, you might think:
👉 “Oh, it’s just a regular chocolate snack.”
But… “Heh heh heh.”
If you don’t know Black Thunder, that’s exactly how it looks—and that is part of the trap.
One of the key tricks of this snack is the gap between appearance and texture.
I thought the same thing at first:
👉 “Isn’t this just a smaller chocolate bar?”
But once you take the first bite,
that texture becomes unforgettable.
And the next time you go to a store,
the second trick kicks in:
👉 Low price.
Before you realize it, you might find yourself unconsciously buying two or three pieces.
Taste & Texture
Here is the cross-section.
Some shapes even look like they have eyes or mouths.
These are known as “Cross-Section Monsters.”
Interestingly, the official website actually features these “monsters,”
each with its own unique name.
This is one of those fun details that makes Black Thunder even more enjoyable.
As for the taste and texture:
Crunchy, intense bite
・Sweet, rich chocolate
・Very satisfying even with just one piece
While it has many “monster-like” qualities,
the reason it has so many fans is clear:
👉 It is carefully crafted in both taste and texture,
making it a next-generation classic chocolate snack that never gets boring.
Another great feature is the wide variety of versions available.
Since each one can be purchased individually,
you can easily try different types one by one.
I will continue introducing more Black Thunder variations in future reviews.
