A unique social media campaign began on the 18th at Shinjuku Metro Promenade. This campaign is celebrating the reopening of the design hotel "Ibis Tokyo Shinjuku." By taking a photo of the "Happy Sleep Pillow" on display at the Metro Promenade (until the 24th) or in the lobby of the Ibis Tokyo Shinjuku (until March 31st), and entering the campaign on Facebook, participants will be entered into a raffle to win a domestic or international hotel stay or a round-trip flight for two to Paris, Singapore, Hong Kong, or Korea, along with a three-night stay. On the 19th, a limited number of pop-style Ibis "Happy Sleep" pillowcases will be given away to all event participants. The hotel is an economical worldwide design hotel owned by the AccorHotels Group, which operates approximately 957 hotels in 55 countries. The results of the campaign will be announced on the campaign website on April 10th.
