Why Japan's 7-Eleven's Egg Sandwich Changed Global Food

Seven-Eleven Japan tested 200 egg salad recipes before choosing this tamago sando. It costs $1.50 and has a 12-hour shelf life. Japanese convenience stores (konbini) have dedicated test kitchens and product development teams. They conduct thousands of taste tests every year. Why? Because a single sandwich recipe can sell millions of units across 21,000 stores nationwide. This became a global case study in premium simplicity, prompting major food retailers worldwide to rethink what convenience food could be. The Ippun Project | Japan.
