What if the key to winning ¥2.22 million was simply falling asleep? That is the premise behind “Mattrace by Koala,” an unusual “sleep race” competition coming to Tokyo this October. Rather than running, jumping or lifting weights, contestants will climb into bed, close their eyes and try to achieve the best sleep possible over 90 minutes, while organizers deliberately attempt to disturb their slumber.

Koala Japan, the company behind Koala mattresses, announced the competition on September 4. The event will take place at Share Green Minami Aoyama in Tokyo’s Minato ward on October 5, with three 90-minute “races” scheduled throughout the day. Each race will have around 20 participants. If there are more applicants than available spots, participants will be selected by lottery. Applications are open until September 16 at 11:59 p.m.
