Alimentation Couche-Tard took its case for its $47 billion takeover of Seven & i straight to the Japanese public on Thursday, marking a change in strategy by the low-key Canadian firm in response to what it described as months of stonewalling by the 7-Eleven owner.

Canada’s Alimentation Couche-Tard has reiterated its determination to acquire Seven & i Holdings, although the operator of Japan’s top convenience store chain has rejected its offer.

Alimentation Couche-Tard Inc. could increase its offer to acquire rival global convenience-store retailer Seven & i Holdings Co. Ltd., but only if the Tokyo-based company engages in talks, Couche-Tard executives said during a news conference held in Tokyo today to make a case for the transaction, Bloomberg reported.
