Answer: Japan

If you’re an American, you can be easily forgiven for thinking that the United States is the 7-Eleven capital of the world. The ubiquitous convenience store chain was started in Texas, there isn’t a state without several dozen of them, and across the entire United States, you’ll find approximately 8,244 of the Slurpee-serving stores.

But there’s something most Americans don’t realize about the franchise. As much as Americans love a good Slurpee and the long hours the stores offer, the Japanese really love them. Not only are there more than twice as many 7-Eleven locations in Japan (approximately 21,215), but four percent of the world’s 7-Eleven stores are found in Tokyo alone—the photo here shows the first location that was opened in May 1974.

In fact, the franchise is such a big deal in Japan that in 1991, Japanese affiliate corporation Ito-Yokado acquired 70 percent of the company, which was reorganized as a subsidiary of Seven-Eleven Japan Co., Ltd in 2005, and is now held by Seven & I Holdings Co., Ltd.
