BrainSleep Inc. (Headquarters: Chiyoda-ku, Tokyo; Representative Director: Atsushi Hirota; hereinafter "BrainSleep") has announced that the BrainSleep Pillow, a pillow for optimal brain sleep and BrainSleep's signature product, will be introduced into the "Hakuba Sleep Reset Journey for Kids" accommodation plan, which focuses on children's sleep and is offered by Courtyard by Marriott Hakuba (Location: Hakuba Village, Kitaazumi-gun, Nagano Prefecture; General Manager: Kentaro Ohira) in conjunction with "Sleep Day" on September 3rd. Children's sleep in Japan, like that of adults, is among the lowest in the world and is a cause for concern. There are also reports that lack of sleep in children affects brain development, and establishing healthy sleep habits from childhood leads to lifelong health. This accommodation plan, which focuses on the "quality of sleep" for children and aims to regulate sleep cycles in the rich natural environment of Hakuba, will be available for reservations on the official website of Courtyard by Marriott Hakuba from July 15, 2025 (Tuesday), in hopes of providing an opportunity for families to re-evaluate their sleep. Background of Introduction The average sleep duration for Japanese people remains short. According to a survey by the Organization for Economic Cooperation and Development (OECD), Japan ranked last among 33 countries with an average sleep duration of 7 hours and 22 minutes. *1 In fact, not only adults but also many children face sleep problems. It has been found that Japanese children have the shortest sleep duration in the world, similar to adults, with a difference of more than 1.5 hours compared to New Zealand, which has the longest sleep duration. *2 A "Sleep Index® for Kids" survey conducted by BrainSleep targeting children aged 3 to 9 nationwide revealed that only 5% were aware that Japanese children have the shortest sleep duration in the world, and for most age groups, there was a discrepancy of more than 1 hour from the recommended sleep duration set by the Ministry of Health, Labour and Welfare. *3 Research reports *4 indicate that insufficient sleep during childhood can significantly affect brain development, with children who sleep less tending to have smaller hippocampi than those who sleep more. This plan aims to provide an opportunity for children, who will shape the future, to become interested in sleep, and for adults and children experiencing it together to re-evaluate their own sleep. Through the experience of the "BrainSleep Pillow," BrainSleep hopes to raise awareness of the importance of sleep among many people and contribute to solving Japan's sleep problems. ※1 OECD Gender Data Portal 2021※2 Mindell JA, et al.

BrainSleep Pillow: The Pillow for Optimal Brain Sleep The "BrainSleep Pillow" is BrainSleep's signature product, with cumulative sales exceeding 300,000 units. Focusing on improving sleep quality, it achieves both excellent breathability and a fit realized by a three-layer, nine-gradation structure using patented technology. 1. Excellent breathability for "cooling the brain and sleeping faster and deeper"More than 90% of the pillow is made of an air layer, preventing heat and humidity generated during sleep from accumulating in the pillow and creating a comfortable sleep environment.2. Three-layer, nine-gradation structure with proprietary patented technology for a personalized fitIt has a rational structure with three types of fibers of different thicknesses and densities: an "adjust layer" that softly conforms to the shape of your head, a "support layer" that firmly supports your head and neck, and a "base layer" that allows air to escape from below. The three-layer, nine-gradation structure, which gradually fits the size of your head and sleeping style, is realized with patented technology. It becomes your own personal pillow each time you use it.3. Washable with water for cleanlinessIt is said that humans sweat about one cup (approximately 200ml) while sleeping. Since more than 90% of the pillow is made of an air layer, its excellent breathability prevents moisture accumulation and keeps it hygienic. Furthermore, not only can the cover be washed, but the inner material is also washable, and it dries quickly, so it can always be kept clean. ＜Product Details＞Product Name: BrainSleep PillowPrice: 33,000 yen (tax included)Product URL: https://brain-sleep.com/products/pillow BrainSleep Pillow for Kids: Nurturing the Brain with a Good Night's Sleep Children have immature thermoregulation, so it is important for them to dissipate heat to sleep soundly through the night. A cooling pack can be inserted inside the pillow to effectively cool the head. The design ensures efficient heat dissipation from the back, maintaining a comfortable sleep environment for children who tend to have higher body temperatures and retain heat easily. Children are said to sweat more than twice as much as adults. The pillow's excellent breathability prevents moisture accumulation and keeps it hygienic. Furthermore, it is washable and dries quickly, so it can always be kept clean. The cover is a button type that can be easily removed and attached by children themselves. During early childhood, start by using the lower part of the pillow, and it can be used for a long time as the child grows and their body shape changes.＜Product Details＞Product Name: BrainSleep Pillow for KidsPrice: 22,000 yen (tax included)Product URL: https://brain-sleep.com/products/pillow_for_kids Courtyard by Marriott Hakuba Courtyard by Marriott Hakuba (Hakuba Village, Nagano Prefecture) is located in one of Japan's leading mountain resorts, offering magnificent nature of the Northern Alps, with high-quality powder snow in winter and activities such as climbing and trekking in summer.
