Yayoi Kusama's family background significantly shaped her unique art style, particularly her struggles with mental health. Growing up in a domineering family in Japan, she faced challenges that fueled her creative expression. Her upbringing was marked by a complicated relationship with her parents, especially her mother, leading to feelings of isolation. This affected her use of polka dots and repetition in her artworks, symbolizing her inner turmoil and desire for freedom. Kusama's experiences with obsessive-compulsive disorders also informed her distinctive visual language, making her art a profound reflection of her personal journey.
