Burger King Japan launches Whopper Festival to celebrate 10 million app members

Burger King Japan is hosting a five-day “Whopper Festival” from September 7 to September 11 to celebrate surpassing 10 million official app members. During this period, five specific Whopper sets will be available at a 300 yen discount each day, starting from 2:00 PM.

The eligible sets include the Whopper Cheese Set, Double Whopper Cheese Set, Smoky BBQ Whopper Set, Teriyaki Whopper Set, and Spicy Whopper Set. These discounts, which represent up to a 28% reduction, are accessible via coupons distributed through the official app. The promotion is valid for both dine-in and takeout, with a limit of three sets per transaction, though delivery services are excluded.

This promotional event comes amid a period of significant growth for the chain in Japan. After shrinking to 77 stores in 2019, Burger King has expanded to 377 stores as of August 2026, with a long-term goal of reaching 600 locations by the end of 2028. The company also reported that existing store sales have exceeded the previous year's figures for 50 consecutive months.
