Brain Sleep Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; Representative Director: Atsushi Hirota; hereinafter "Brain Sleep") began pre-orders for the "Brain Sleep Pillow Rirone Edition" (hereinafter "Pillow Rirone Edition"), a pillow developed in collaboration with "RIRONE," a brand led by Gento Kono, a prominent educational YouTuber with over 1.67 million subscribers, on November 29 (Saturday) on the Brain Sleep official website. This pillow is designed to restore balance to the brain and body. The "Pillow Rirone Edition" uses the same super-breathable material as the "Brain Sleep Pillow," a pillow that helps the brain sleep. It is used by connecting the and the , and is structured to balance the neck and shoulder blades during sleep, addressing both sleep quality and posture. This pillow supports the best condition for continuous learners, leading them to the optimal solution for sleep. Background of Development Japan has the shortest average sleep duration among the 33 OECD member countries*1, and while the Ministry of Health, Labour and Welfare recommends "8 to 10 hours" of sleep for junior and senior high school students*2, the actual average sleep duration is about 6 to 7 hours*3, falling significantly below the recommended time. With difficulty in securing sufficient sleep, improving sleep quality becomes crucial. Sleep quality directly impacts performance, and Brain Sleep's annual "Sleep Deviation® Survey," conducted on 10,000 people nationwide, revealed in its 2024 edition*4 that individuals with higher productivity tend to have "higher sleep quality." The "Pillow Rirone Edition" was initiated by Mr. Kono, a user of the "Brain Sleep Pillow," who proposed that he wanted to "better support the sleep of continuous learners." This collaboration was realized due to the alignment between Mr. Kono's philosophy, which emphasizes the importance of sleep in academics, and Brain Sleep's vision of sleep reform. Not only students, but many people today have developed a constant forward-leaning posture due to prolonged use of PCs and smartphones, which causes their shoulder blades to open up. This postural imbalance affects daily performance. Therefore, the "Pillow Rirone Edition" aims to improve both sleep quality and posture with a new approach: a unique structure that balances the neck and shoulder blades during sleep, pursuing efficient sleep for continuous learners. *1 OECD Gender Data Portal 2021 https://www.oecd.org/gender/data/*2 Ministry of Health, Labour and Welfare "Sleep Guide 2023 for Health Promotion"https://www.mhlw.go.jp/stf/seisakunitsuite/bunya/kenkou_iryou/kenkou/suimin/index.html*3 Ministry of Internal Affairs and Communications "2021 Survey on Time Use and Leisure Activities"https://www.e-stat.go.jp/stat-search/files?page=1&toukei=00200533&tstat=000001158160 *4 Sleep Deviation® Survey 2024 (n=10,000)https://brain-sleep.com/pages/research2024 Product Features of "Brain Sleep Pillow Rirone Edition" 01 NECK & BACK CONDITIONINGLoosen, stretch, support, and adjust the head, neck, and shoulder blade areaIt soothes the shoulder blades that have opened due to prolonged desk work, PC, and smartphone use in a forward-leaning posture, as well as tense muscles, and gently loosens them. By supporting them in a comfortable position, it leads to a natural state of balance. ＜PILLOW＞ Provides comprehensive care for the back of the head, sides of the head, and neck during sleep. By stimulating from multiple angles simultaneously, it addresses tension in the overworked head and neck, and the brain pot gently stimulates the back and sides of the head during sleep, relieving tension around the head and supporting natural circulation. The double-stretch structure with different strengths allows for selection based on daily neck condition. The 3-zone design, with a softer center and firmer sides, supports turning over, allowing for smooth turning without the head sinking too deeply when sleeping on your side. ＜BACK STRETCHER＞ Stretches the area around the shoulder blades during sleep. It brings the left and right shoulder blades together, addressing the muscles around the shoulder blades that have become stiff from prolonged forward-leaning posture. With the ideal curve of the neck and stable position of the shoulder blades, the rib cage naturally expands, opening the airway and leading to relaxed breathing. 02 SUPER BREATHABLESuper breathable material for deep sleepTo achieve good quality sleep, it is important to maintain appropriate temperature and humidity within the bedding. Highly breathable material dissipates heat from the head, leading to deep sleep. Over 90% of the material is an air layer, preventing heat and moisture build-up during sleep, controlling the optimal temperature and humidity for sleep, and creating a comfortable sleep environment. Its excellent breathability, far superior to urethane or feather pillows, allows for comfortable sleep until morning. 03 SUPER CLEANWashable with shower for cleanlinessIt is said that humans sweat about one cup (approx. 200ml) while sleeping. Its excellent breathability prevents moisture buildup and keeps it hygienic. Furthermore, it can be washed with water and dries quickly, so it can always be kept clean. Limited quantity!

Comment from Gento Kono Through my daily studies and work, I have come to realize that the quality of sleep directly affects my thinking and concentration the next day. Prolonged desk work and studying can disrupt posture, and the physical burden can lead to a decrease in sleep quality. This pillow is designed to adjust the neck to the shoulder blades during sleep, enabling deep breathing and high-quality rest. Only when the body is in good condition can effort lead to results. This is a product that pursues the theoretical optimal solution, and I want everyone who is dedicated to learning to use it. Gento Kono Graduated from the University of Tokyo School of Medicine. While enrolled, he achieved outstanding results in various fields, including passing the bar examination and obtaining Eiken and Sūken Level 1 certifications.
