Yayoi Kusama, the renowned Japanese artist featured in the documentary "Kusama: Infinity," has struggled with mental health issues throughout her life, specifically obsessive-compulsive disorder (OCD) and hallucinations. These experiences have profoundly influenced her art, leading her to create immersive installations and patterns that reflect her inner world. Kusama's unique perspective and resilience have made her a significant figure in contemporary art, showcasing the interplay between her mental health and creativity.

In the documentary "Kusama: Infinity," it is highlighted that Yayoi Kusama has created multiple infinity rooms, with over 20 of these immersive installations existing worldwide as of the film's release. These rooms, characterized by their reflective surfaces and use of lights, create an illusion of infinite space and are a significant part of Kusama's artistic expression. The most famous of these is "Infinity Mirror Room - Phalli’s Field." Kusama's work continues to evolve, so the number may change with new creations.

In "Kusama: Infinity," visitors to Yayoi Kusama's infinity mirrored rooms are typically allowed to stay for about 45 seconds to 2 minutes. This time limit is often set to manage the flow of guests and to preserve the experience, as the rooms can become crowded. The brief duration allows individuals to fully immerse themselves in the experience of the infinite reflections and vibrant colors without overstaying, ensuring everyone has a chance to enjoy the artwork.

Yayoi Kusama's most famous piece is "Infinity Mirrored Rooms," particularly "The Obliteration Room" and "Infinity Mirror Room - Phalli's Field." These installations create immersive experiences using mirrors and repetitive patterns, often featuring polka dots, which reflect her themes of infinity and self-obliteration. Kusama's unique approach to art has made her a significant figure in contemporary art, and her works invite viewers to engage in a dialogue about perception and existence.
