■ Background

KURA ONE🄬 is a small-capacity sake brand offered by id10 japan corporation which aims to change the "unreachable" to "deliverable" category of sake. It is a brand of sake in small-capacity aluminum cans. Sake from sake breweries around Japan that have won awards in Japan and abroad are packaged in 180ml aluminum cans and delivered to purchasers along with stories of how to enjoy and be amazed by the sake. Sales will begin in January 2023 and exports have already begun with inquiries from more than 10 foreign countries.


This collaboration was realized through the empathy between "QAQA," a quiz short video SNS that can deliver the strong desire and enthusiasm that people and companies working on something have for the concept of "KURA ONE🄬" of "Delivering the Unreachable" and #SOZO Museum of Art, a museum specializing in AI art that uses AI to create free ideas and thoughts.
The quizzes to be given this time will include questions on the basics of sake, the passion behind "KURA ONE🄬" and sake breweries throughout Japan, in order to deliver the charm of "KURA ONE🄬" as it is.


"QAQA" will continue to "deliver" the strong thoughts and passion of people and companies in the form of vertical quiz videos, thereby becoming a point of contact with more people and helping to convey their thoughts and passion in a fun and casual manner.

About「KURA ONE🄬」

KURA ONE🄬 is a sake brand that changes the problems of communication and delivery from "unreachable" to "deliverable," such as the problems of containers that are heavy, undrinkable, breakable, or do not fit in a refrigerator, the problems of language, such as not understanding the technical terms for sake or not understanding Japanese, and the problems of delivery, such as not being able to purchase sake.

Sake that can be enjoyed and experienced as a language of stories and surprises is carefully selected from marketed products brewed by award-winning sake breweries in Japan and abroad and commercialized as the "KURA ONE🄬" collection. The 180mL aluminum cans, which are lighter and smaller in volume, reduce shipping costs and allow those who are not yet familiar with sake to easily try a small amount of the best sake.
