An exciting new campaign is launching at 7-Eleven stores across Japan, allowing you to enjoy the thrill of Major League Baseball (MLB) alongside your daily shopping. Starting Monday, March 16, 2026, members of the 7-Eleven Japan app can participate in a special program to predict game outcomes and win coupons.

Major League Baseball (MLB) is the world’s premier professional baseball league, featuring 30 teams across the United States and Canada. It is incredibly popular in Japan, where many star players from both nations compete at the highest level. Through this campaign, the 7-Eleven app provides an entertaining experience by allowing fans to predict the results of these high-stakes games.
15 Rounds Over Three and a Half Months: Participation Requirements
This campaign will run for approximately three and a half months, from Monday, March 16, to Sunday, June 28, consisting of 15 rounds in total. Since fans can challenge new predictions every week, the excitement lasts throughout the spring season.
Participation requires the following two steps:
- Register for the 7-Eleven App: You must install the official app used at 7-Eleven stores in Japan.
- Link with a LINE Official Account: You need to add the 7-Eleven official account as a friend on “LINE”—Japan’s most popular messaging app—and complete the authentication process.
Even if you haven’t added the account yet, the system is designed to automatically register you once you grant permission on the campaign authentication screen.
