■Japan's Increasingly Severe Summers
In recent years, Japan's summers have become increasingly harsh, with a rise in extreme heat days and heatstroke risks becoming a significant social issue. The importance of heatstroke prevention measures is growing year by year in outdoor work environments, sports scenes, and outdoor activities. Against this backdrop, cooling wear is attracting attention as "wearable heatstroke prevention." FREEZETECH is a cooling wear brand that employs a unique "Ice Blast" cooling technology that generates coolness in response to sweat and moisture. The special cooling print applied to the fabric reacts to sweat and moisture to create a cooling sensation, which is further enhanced by airflow.
■Collaboration with Masato
Masato was appointed as FREEZETECH's brand ambassador in 2024. He has been promoting the brand's appeal through visuals for in-store promotions nationwide, various promotions, and talk events. Due to the positive response and high brand affinity, it has been decided that Masato will continue his activities as ambassador in 2026. Moving forward, Masato and FREEZETECH will continue to disseminate "wearable heatstroke prevention" to those working in hot environments and those enjoying sports and outdoor activities.
