FANCL's Innovative Approach to Summer Heat Risks

FANCL, a renowned Japanese skincare and health supplement company, has announced an exciting new initiative in collaboration with Matsuya Ginza. From August 1 to August 31, 2026, they will conduct a practical experiment for their newly developed product, the "Shi-on Seal" in the beautifully themed "Beauty Beer Garden" located on the rooftop of Matsuya Ginza in Tokyo's Chuo Ward. This innovative seal is a joint development with TOPPAN Inc., aimed at addressing rising concerns over heat-related risks during the scorching summer months.

Addressing a Social Concern

As global warming continues to impact temperatures worldwide, the risk of heat stress is becoming a significant social problem, particularly in urban settings. FANCL's core mission is to "eliminate the 'injustice' in society with a sense of justice." This product exemplifies that philosophy by offering a solution to mitigate the negative effects of summer heat.

The Shi-on Seal detects changes in deep body temperature through color variations. This innovative approach means that wearers can visualize their rising body temperatures, prompting preventive measures against heat-related health issues. During the experiment, approximately 1,500 employees working outdoors at the Ginza Beer Garden will be assessed for the seal's practicality and effectiveness in combating heat risks.

Beyond Matsuya Ginza, further tests will target outdoor sports events and factory environments where the risk of overheating is prevalent. The outcomes of these experiments will help FANCL explore the potential for this innovative product to be utilized effectively across various scenarios, driving development and enhancements targeted at ensuring safer summer working conditions.
