## 'Nama Jokki Can' Recognized with Invention Award at National Awards 2026
Asahi Breweries, Ltd. has been honored with the 'Invention Award' at the Reiwa 8 (2026) National Invention Awards, hosted by the Japan Institute of Invention and Innovation. The award was granted for the 'Invention of a Canned Beer Combining a Foaming Body and a Full-Open Lid.'
The recognized technology is the innovative container system known as the 'Nama Jokki Can.' When the lid is fully opened, fine bubbles appear naturally, allowing consumers to enjoy the taste and texture of draught beer served in a mug at a restaurant from the comfort of their home. As a world-first product launched in April 2021 as 'Asahi Super Dry Nama Jokki Can,' it has received overwhelming acclaim from consumers.
### The Core Technology: Microscopic Crater Structure
The defining feature of the 'Nama Jokki Can'—its natural foaming—is made possible by a 'microscopic crater-like structure' created by a special coating applied to the can's interior. Key technical specifications include:
- **Precision Bump Design**: Distribution of 200 to 1,200 bumps (5–20㎛ diameter) per square millimeter.
- **Complex Layering**: High-density combination with even smaller bumps (less than 0.5–5㎛ diameter).
- **Foaming Mechanism**: The sudden change in air pressure upon opening triggers the continuous rise of fine bubbles from these microscopic structures.
In addition to the foaming tech, safety is a priority. The 'Full-Open Lid' is specifically designed to prevent any injury to the hands or mouth, enabling a seamless 'mug-like' drinking experience directly from the can.
### Market Impact and Future Outlook
This invention overturned the industry norm of 'preventing foam in canned beer' and delivered a new value proposition of 'a bar-like experience at home' to a wide range of generations, including young adults. The 'Jokki Can Series' has now expanded beyond Asahi Super Dry to include limited-edition releases of other brands like 'Asahi Style Free' and 'Clear Asahi.'
The 'Asahi Super Dry Nama Jokki Can' refreshed its package design on March 10, 2026. Since April 27, a new TV commercial titled 'Different Expressions' has been airing to promote its unique value of 'delicious foam,' maintaining strong sales momentum.
Asahi Breweries continues to strive for 'creating deliciousness beyond expectations and a fun living culture' through ongoing technological innovation.
#### About the National Invention Awards
