The campaign is split into two waves:
| Period | Start Date | End |
|---|---|---|
| Wave 1 | May 12 (Mon) | Until Wave 2 begins |
| Wave 2 | May 19 (Mon) | Around June 1 |
Every item is sold at its regular price. There is no extra charge for the larger size.
Standout Products
All 12 items are upsized by at least 50%, but a few are especially worth highlighting.
New York Cheesecake Ice Bar (Kajiru New York Cheesecake)
This popular ice cream treat comes in at roughly 2.5 times its usual size. It’s one of 7-Eleven’s best-selling frozen items, and at the same price, it’s an easy pick.
Tomita-Supervised Mega Pork Ramen (Chuuka Soba Tomita Deka Buta Ramen)
The noodles, soup, vegetables, and pork fat have all been increased. This is a collaboration with the famous ramen shop Tomita, and it’s ideal if you’re looking for a filling meal.

How to Make the Most of It
- Pay with nanaco: Using 7-Eleven’s nanaco card earns you points on top of the upsized deal
- Use upsized items for meals: The bigger ramen and rice balls can serve as a full lunch or dinner, boosting your cost-per-meal value
- Grab the cheesecake ice bar early: The 2.5x size has been generating buzz, so popular stores may sell out quickly
