McDonald's Japan will introduce a new pricing model based on "location" from September 13 instead of the existing prefecture-based area classification for setting regional prices.

The introduction of this new model will be implemented based on the results that have been verified at several stores from April. The regional prices, which were previously divided into 6 categories by prefecture, will be reorganized into 9 categories based on location.

As a result, the prices of some products will be raised at stores in areas where land prices are high, but the prices of " Value Picks " and "McDonald's" will remain unchanged, and the prices of "Happy Set" will drop at about 300 stores. In addition, less than 40% of all stores are subject to adjustment this time.
