Japanese convenience stores (Konbini) frequently run campaigns where you get limited-edition goods when you buy drinks.Starting Tuesday, January 20, 2026, at 10:00 AM, a new campaign begins at 7-Eleven stores nationwide in Japan. During this period, purchase two bottles of the “Monster Energy” energy drink series at once, and you’ll receive one “Monster Original Keychain” on the spot. It’s a cool item featuring the Monster Energy logo and world.
Two Rare Keyholder Designs Available in Limited Quantities
There are two types of keyholders available as this campaign’s bonus. Note that each store only has “20 units available on a first-come, first-served basis.” This means only 10 units of each design will be stocked. Competition is expected to be fierce. The campaign ends once stock runs out, so some stores may sell out immediately after the campaign starts.
Motocross Bike Design

The first design features a motocross bike motif. Monster Energy is globally renowned as a motorsports sponsor. It measures approximately 102mm in height, 33mm in width, and 7mm in thickness. Its elongated silhouette captures the bike’s dynamic energy. It makes a great accent when attached to a bag zipper.
Guitar Design

The second design features a guitar, perfectly suited for the rock and heavy metal music scene. It measures approximately 115mm in height, 22mm in width, and 7mm in thickness. It boasts a stylish shape with a long neck. Both designs have a black base, finished with the Monster Energy logo prominently displayed for a cool look.
Campaign Period and How to Participate at Japanese Convenience Stores
The campaign runs from Tuesday, January 20, 2026, at 10:00 AM until Monday, February 2. However, as mentioned earlier, it ends once prizes run out.
Participation is simple, but involves a system unique to Japanese convenience stores. The purchaser must select “one keychain of their choice” from the display area and take it to the register along with two qualifying drinks.The cashier will not automatically hand you the prize. You must place the prize in your basket yourself and complete the payment.
