Understanding changes from age 44: 'f44 Balance Lab.' 3-day event in Marunouchi

Q'sai Co., Ltd. (HQ: Fukuoka, CEO: Junro Ishikawa) will hold an interactive event called 'f44 Balance Lab.' at Marunouchi Happ. Stand & Gallery in Tokyo for three days, from Tuesday, June 9, to Thursday, June 11, 2026.

Under the theme of 'listening to your body's voice,' the event offers panel exhibits about physical and mental changes that often occur around age 44, as well as olfactory reaction analysis. It aims to provide busy women working in the Marunouchi area with a moment to stop and focus on their own bodies in the midst of their daily routines.

Background of the Event Women in their 40s and 50s, often called the 'responsibility generation' due to their busy lives at work and home, tend to overlook physical and mental fluctuations as mere fatigue. Research, including studies at Stanford University, indicates that the body often undergoes changes around age 44, making this a period where signs of aging are more noticeable.

This event was planned with the desire to provide women with a starting point to recognize these changes early and enjoy their daily lives more positively. Through panel exhibits and olfactory reaction analysis, the event offers a real-world experience to 'know your current state.'

Event Content 1. Panel exhibit: 'Physical and mental changes from around age 44' Panels introduce common changes in heart and body that occur around age 44, along with results from the company's survey on health in the 'responsibility generation.' It aims to help people who feel 'something is different' understand their changes correctly.

2. Olfactory reaction analysis (Limited to women in their 40s–50s, free) 'Olfactory' is the most primitive sense that reaches the instinct, less influenced by prejudices. This analysis method utilizes this characteristic to understand mental and physical status through reactions to scents, helping in self-care and life improvement.

3. Original drink: 'Body-caring Pomegranate & Berry Soda' Available free of charge to those who participate in the olfactory reaction analysis. It is a drink designed for women who want to spend their days comfortably, based on pomegranate and blended with cranberry, honey, and mint.

4. New product gift (Limited quantity, first-come, first-served) Those who register for the official LINE account and answer a survey after the olfactory reaction analysis will receive one of Q'sai's new products.
