7-Eleven

7-Eleven is a worldwide chain of convenience stores which started in Irving, Texas, USA in 1927. A majority of its stores internationally are based in Japan, with over 18,700 stores out of the 59,000+ in operation around the world located in that area.

One of the promotional events of the stores in Japan are "stamp rallys" where visits to a 7-Eleven can result in rewards if participants have stamp books. Prizes range from stickers for kids to raffles or points for for prizes such as collectible toys or clothing merchandise. 7-Eleven, much like McDonalds, can also be a location of a Ganbaride or later Ganbarizing card giveaway. Some of the ads for these promotions feature the Kamen Riders and in some cases, the Shocker Combatmen.
