Aside from Louise Bourgeois who’s now 98, Yayoi Kusama is probably the oldest woman artist from Japan also known as the “polka dot or pumpkin lady.”   The polka dots, her latest installation at the Gagosian, are a recurrent motif issued from her childhood’s hallucination which she explored in the fifties.  Her works and installations all share an obsession with repetition, pattern and accumulation. She describes herself as an obsessive artist and has struggled with mental illness. Today, she lives and work in Japan.  From her own decision, she now lives in a mental institution in Tokyo, nearby her studio.
