Living and Fabric Care

In recent years, there have been major changes in lifestyles and values as well as a diversification of living environments, and awareness and interest in personal hygiene and housekeeping habits have increased. By quickly grasping these changes and utilizing Lion’s strengths in cleaning and sanitizing technologies, as well as the extensive knowledge we have acquired by observing the daily lives of consumers, we are developing products that propose new habits and values that suit the diverse lifestyles of every individual.
