Proposing Heat Management and Styling for Every Scene: Choosing Clothes for a 'Hot Summer' with 'Tekizai Tekisho' (Right Clothes for the Right Heat), Supervised by Heatstroke Specialist Dr. Yasufumi Miyake

Uniqlo is introducing a new concept called 'Tekizai Tekisho' (Right Clothes for the Right Heat), which encourages choosing the best clothing based on the specific nature of the heat. A special feature site will be released sequentially starting in mid-June, with the first installment focusing on 'Tekizai Tekisho for the Rainy Season.' In recent years, Japan has experienced record-breaking summer heat, but the nature of this heat varies. From the humid, muggy conditions of the rainy season to the piercing direct sunlight of midsummer and the tropical nights where heat lingers, the quality of heat changes depending on the time and environment. To stay comfortable, it is crucial to choose attire that matches these diverse heat conditions. 'Tekizai Tekisho' is a new approach to clothing selection that involves choosing materials, functions, and designs, as well as layering and styling, to control comfort through clothing based on the heat and environment at any given time. This project was organized under the supervision of Dr. Yasufumi Miyake (Emergency Specialist), a heatstroke expert and chairman of the 'Heatstroke Prevention Call-out Project,' incorporating medical insights. Uniqlo aims to contribute to a more comfortable life through clothing by widely promoting this new concept and offering a fresh perspective on choosing what to wear. Supervision: Dr. Yasufumi Miyake, Chairman of the Heatstroke Prevention Call-out Project. He is a specialist and instructor at the Japanese Association for Acute Medicine, a member of the Committee on Heatstroke and Hypothermia, and Director of the Heatstroke Research Institute. Since 2011, he has led the 'Heatstroke Prevention Call-out Project' in collaboration with the government to promote heatstroke prevention nationwide. He is a heatstroke specialist who educates many people through media appearances while working on the front lines. Rainy Season Heat Points: The humid, muggy rainy season is arriving earlier. It is important to note that high humidity makes it difficult for sweat to evaporate. For those who generate heat through housework or work, there is a risk of rising body temperature. The key to countermeasures is to efficiently dry sweat with clothing and adjust for sudden temperature differences caused by rain or air conditioning through 'functional layering.' The second installment, focusing on extreme heat, is scheduled for release soon. Let's make this summer smart and comfortable with the perfect LifeWear. New Definition of 'Extreme Heat Days' (40°C+): Large Thermometers Installed. As part of efforts to combat extreme heat, starting Monday, June 1, large thermometers will be installed in select stores nationwide, mainly in station-based locations, to help customers intuitively grasp the heat level of the day. By displaying 'Midsummer Day' or 'Extreme Heat Day' in conjunction with the temperature, customers can intuitively know 'what kind of heat it is today' and choose clothes accordingly. Participating stores include JR Ikebukuro Station Central 1 Gate, Wing Shimbashi, Namba Walk, Nagoya Esca, and Hakata Underground Mall. Period: From June 1, 2026. 'Tekizai Tekisho' in the Workplace: The concept is spreading beyond daily life into the workplace. Odakyu Electric Railway has introduced AIRism Cotton Kanoko Polo Shirts as summer uniforms since 2025 to reduce the burden on staff performing safety checks and guidance on platforms during summer. They believe that creating a comfortable working environment during hot periods leads to the provision of safe, secure, and high-quality services.
