Actors Satoshi Tsumabuki and Akari Takaishi appeared in a promotional video today discussing the proper way to use cold water baths [1].

The video serves as a lead-in for a new McDonald's television commercial campaign titled "Midday Temptation: L is Free," which offers a specific consumer incentive [1, 2].

During the interview, Takaishi spoke about her experience with sauna culture and cold plunges. She said, "I think I'm going to get hooked on saunas" [1]. Takaishi described a session where she remained in the cold water for about 10 minutes [2].

Tsumabuki reacted to the length of her soak with a joke about the health risks of such a long exposure to cold. He said, "You'll catch a cold" [1].

The lighthearted exchange was released as part of the marketing push for the upcoming McDonald's promotion. The campaign is scheduled to begin on July 6 [1].

For a period of five days, from July 6 through July 10, the company will provide a free size upgrade [1]. Customers will be able to upgrade their order from a medium size to a large size at no additional cost [1].

The video was filmed in a studio setting designed as an interview, blending celebrity banter with the brand's promotional goals [1].

“"I think I'm going to get hooked on saunas"”

By utilizing a conversational, 'behind-the-scenes' style interview between high-profile actors, McDonald's is employing a soft-sell marketing strategy to generate organic social media engagement before the official launch of its short-term promotional window.
