For students and busy business professionals living in Japan, “Calorie Mate” is an indispensable item. This block-shaped food provides easy nutritional support and is considered a “soul food” for Japanese youth, especially those striving in exam studies or club activities.
Currently, at 7-Eleven (Konbini) stores across Japan, a unique campaign is underway where you can win this Calorie Mate using your “knowledge.”
The project is titled “Super Good Questions Drill 10 (Chou-Ryomon Drill 10).” It is a generous event where you can receive a free Calorie Mate by challenging quizzes supervised by “Z-kai,” an institution famous for guiding students through Japan’s difficult university entrance exams, and answering 5 questions correctly in a row. Starting on Tuesday, February 3, 2026, this project is not just a giveaway campaign, but intellectual entertainment that lets you feel the Japanese educational culture.
A Challenge from Japan’s Top Educational Institution “Z-kai”
This campaign is a quiz event held using “LINE,” the most popular messaging app in Japan. “Z-kai,” which supervises the questions, is known for its high-level educational services and has led many students to top universities. Therefore, the quizzes presented are high-quality problems that won’t be easy to solve.
There are no restrictions on participation eligibility. Not only current high school students but also Japanese adults and people from overseas interested in Japanese culture can participate. Please test your knowledge and aim to win a Calorie Mate while enjoying it as brain training.

School vs. School! A Gift Project for All Students
This campaign includes not only individual challenges but also a school ranking battle. This is a project that symbolizes Japanese school culture, which values club activities and school events.
High schools with many participants achieving 5 consecutive correct answers will be announced in a ranking format. If a school enters the top 10, Calorie Mate Blocks (2-pack) for “all students” will be donated to that school. The sight of hundreds or thousands of Calorie Mates arriving will surely create excitement like a Matsuri (Festival).
Alumni can also contribute by registering their alma mater or a school they wish to support. Alumni (OBs/OGs) uniting for their old school is also a very Japanese way to enjoy this event.
