A new addition to the Black Thunder family is arriving at convenience stores across Japan. Yuraku Seika Co., Ltd. (headquartered in Kodaira, Tokyo) is releasing "Ichigo no Thunder Hitokuchi Size Ichigo-kan 200% Choe" (Strawberry Thunder Bite-Size, 200%+ Strawberry Intensity) on Tuesday, April 7, 2026, exclusively at convenience stores nationwide.
Compared to the company's Ichigo no Thunder Mini Bar
The new product was inspired by the existing regular product "Black Thunder Hitokuchi Size," which is already marketed as offering "200%+ chocolate flavor." That line has earned a strong following for delivering an overwhelming sense of satisfaction in every bite-sized piece.
Building on the momentum of the "200% over" series, the brand chose strawberry as the theme for its first-ever flavor expansion—a fruit that communicates intensity through its aroma, tartness, and vivid color in a single bite, making it an ideal match for the "200% over" concept. The product uses a generous combination of strawberry chips and freeze-dried strawberry powder to deliver not just sweetness but also the characteristic sweet-and-sour taste of real strawberries.
To let the strawberry flavor take center stage, the team opted for the brand's "basic cookie"—a simpler-flavored biscuit from their in-house lineup—pairing Black Thunder's signature crunchy texture with an overwhelmingly vibrant strawberry taste.
Product Highlights
● First-ever flavor variant in the Black Thunder "200% over" series
● Crunchy texture meets overwhelmingly intense strawberry flavor
● Eye-catching strawberry-forward packaging
First-Ever Flavor Variant in the "200% Over" Series
The current regular product "Black Thunder Hitokuchi Size" is marketed under the tagline "200%+ Choco Flavor" and has been praised by many customers for delivering an overwhelming sense of satisfaction in every bite.
Riding the success of the "200% over" series, Black Thunder is now venturing into its first-ever flavor expansion as the next challenge for the brand.
"Ichigo no Thunder Hitokuchi Size Ichigo-kan 200% Choe" responds to the "expectation for intensity" cultivated by the "200%+ Choco Flavor" variant, this time putting strawberry flavor in the spotlight.
Keeping the satisfying chewiness that Black Thunder is known for, the new flavor aims to deliver a "200%+ over" experience in a different dimension from the classic chocolate version, offering a fresh kind of satisfaction.
Crunchy Texture Meets Overwhelmingly Intense Strawberry Flavor
The standout feature of this product is its overwhelming strawberry intensity. In addition to strawberry chips that provide tartness and a crunchy texture, the recipe generously incorporates freeze-dried strawberry powder to enhance the sweet-and-sour taste and vibrant color. The result is a flavor profile where not only strawberry's natural sweetness but also its refreshing acidity comes through clearly.
A simple-flavored basic cookie was chosen to let the strawberry shine even more. Paired with Black Thunder's distinctive crunch—born from a combination of biscuit and cookie—the strawberry intensity can be fully savored in every bite.
The final product delivers an overwhelming "200%+ strawberry" experience that satisfies in just one bite.
Eye-Catching Strawberry-Forward Packaging
The packaging was designed to instantly convey the product's "200%+ strawberry intensity." The words "200% over" are boldly placed at the center, with a vivid red color scheme emphasizing the richness of the strawberry. Piled-high strawberry sizzle imagery is used to visually express the deep strawberry flavor, creating a package where strawberries are unquestionably the star.
