Nippon Sigmax Co., Ltd. (Headquarters: Shinjuku-ku, Tokyo, President & CEO: Yosuke Suzuki), which operates 'MEDIAID,' a supporter brand for daily life born in Japan, will exhibit at six exhibitions held from April to July, increasing its number of appearances from last year in response to the urgent need for heatstroke countermeasures. At the booth, the 'MEDIAID Icing Gear Vest 2', a Peltier-type cold water circulation suit launched in 2025, will be displayed. We will also provide try-on experiences, introduce implementation case studies, and offer information on trial rentals.
### ■ The number of casualties due to occupational heatstroke reaches a record high; countermeasures at workplaces are an urgent issue
In response to the increasing number of emergency transportations due to heatstroke year by year, starting June 1, 2025, heatstroke countermeasures in the workplace have been made mandatory with penalties following the revision of the Ordinance on Industrial Safety and Health. Furthermore, in March 2026, the Ministry of Health, Labour and Welfare mandated that all workplaces take heatstroke prevention measures based on the 'Guidelines for the Prevention of Heatstroke in the Workplace.' (*1)
However, while the strengthening of countermeasures progresses, regarding the occurrence of heatstroke in the workplace in 2025, the number of casualties, including deaths and those requiring four or more days of absence from work, reached a record high of 1,681. (*2)
Looking by industry, the manufacturing industry accounted for 337 people, followed by the construction industry with 278 people (preliminary figures from 2025 to the end of December 2025), indicating that a serious situation continues, especially in workplaces with frequent operations in high-temperature environments.
Behind this is the challenge that, due to the intensifying heat every year, conventional measures are making it difficult to achieve sufficient effects; for example, fan-equipped wear ends up circulating hot air, and ice packs have short cooling times, making them difficult to operate.
To address these challenges, we developed the 'MEDIAID Icing Gear Vest 2' by leveraging the expertise our company has cultivated in the medical field. This product can cool a wide area for about 5 hours even in high-temperature environments exceeding 35°C, and can be utilized as a new heatstroke countermeasure in labor sites such as the manufacturing and construction industries.
Receiving high evaluations from the field since its launch in 2025, we are strengthening our proposals for heatstroke countermeasures at work sites like manufacturing and construction, increasing our number of exhibition appearances since last year to exhibit at six trade shows between April and July.
