Convenience Coffee

Major convenience stores have a large number of stores, with Starbucks having 2,000 stores in Japan and 7-Eleven having 20,000.
Starbucks is a major cafe chain and has the largest number of stores in Japan, but the huge distribution network of convenience stores far surpasses even those of major cafe chains.
FamilyMart has 16,000 stores and Lawson has 14,000, so if each of these stores had a cafe, they would be the largest cafes.
The beans supplied to these stores by roasters are also on a large scale.

One of the reasons for the rise of convenience store coffee is the improvement of coffee machines.
While Seven-Eleven's coffee machines previously required customers to choose the size of their coffee when brewing, the machine automatically determines the size and brews the coffee when a cup is placed in the machine.
Improvements have been made to improve service, including adjustment of brewing temperature, precise control over bean grinding, and multilingual touchscreens.
