Major Japanese snack manufacturer Calbee is introducing an exciting new product. It is the latest entry in the “Ultra-Thin Potato Chips” series, where potatoes are sliced to the extreme limit: “Ultra-Thin Potato Chips Sour Cream & Onion.” Starting May 4, 2026, it will be available for a limited time at convenience stores (known in Japan as “Konbini”) across the country.
Combining the light “shaku-shaku” texture achieved through a unique manufacturing process with a refreshing acidity and richness, this snack is perfect for the upcoming warm season.
A History of “Calbee’s Thinnest” Brand Born After 6 Years of Development
The “Ultra-Thin Potato Chips” series originated from the “Thin Potato” brand launched in 2020. To create the thinnest potato chips in Calbee’s history, the company introduced its first-ever specialized frying technology.
Using 100% sunflower oil, hundreds of prototypes were made to maximize the thinness. The development process took a staggering six years. What they finally achieved was this small shape and incredible lightness.
In 2024, the brand was renamed “Ultra-Thin” to better communicate its key feature at a glance. Today, it has become a new face of the long-beloved “Calbee Potato Chips” series, gaining popularity across Japan, led by the standard “Special Salt” flavor.
Half the Thickness of the Popular “Katai-age Potato”! Unique Texture Created by Extreme Thinness
The biggest secret of “Ultra-Thin” lies in its staggering thickness. Before frying, the slices are only about half as thick as “Katai-age Potato” (Hard-Fried Potato), a very popular thick-cut chip in Japan.
This extreme thinness creates a unique, light rhythmic crunch described as “shaku-shaku” the moment it enters your mouth. Another major feature is the use of 100% sunflower oil for frying.
This reduces greasiness and preserves the natural flavor of the potatoes, resulting in a light aftertaste. The “Ultra-Thin” texture, which makes it hard to stop eating once you start, showcases the evolution of Japanese snack culture.
Evolved from the 2025 Version! A Golden Balance of Richness and Acidity
The flavor debuting this time is an evolved version of the “Sour Cream & Onion” flavor that was released in February 2025 to great acclaim. Following that hit, the taste has been further refined.
Specifically, while maintaining harmony with the sweetness of the onions, the characteristic richness and refreshing acidity of the sour cream have been even more pronounced. Furthermore, by adding garlic as a secret ingredient, the savory “umami” spreads with every bite, making it even more addictive.
Designed for the upcoming warmer weather, it provides a refreshing yet deeply satisfying taste experience.
Look for the Refreshing Green! Package Design Capturing the Early Summer in Japan
The package uses “green” to directly evoke the light texture and refreshing taste of the product. An appetizing photo of sour cream and onion is placed in the lower left, creating a design that catches the eye on Japanese store shelves.
The packaging, which conveys a “refreshing feeling” visually, has an allure that makes you want to reach for it. If you see this vibrant green on the shelves of a Japanese Konbini, that is the sign of “Ultra-Thin.” You can enjoy the sophisticated flavor along with the surprising texture.
