Yayoi Kusama died on 14 August at a hospital in Tokyo, aged 97. Her studio announced the news on 27 August, saying she did not let go of her paintbrush until just before the end. For nearly fifty years she had lived, by her own choice, in a psychiatric hospital, working each day from a studio nearby. She was also, by almost any measure you care to use, the most famous artist on the planet.
Which raises the question that followed her name around, and the one this studio gets asked more than any other: was she an outsider?
The short answer is that she does not fit the definition. Kusama trained formally, planted herself at the centre of the New York avant-garde, and died as the art world’s most celebrated figure. But her work came out of hallucination and compulsion, she spent almost five decades in a psychiatric institution by choice, and the establishment treated her as an outsider for decades before it crowned her. She was the great border case. The border did not survive her.
What is outsider art?
Outsider art, the tradition this studio takes its name from, comes out of Jean Dubuffet’s idea of art brut: raw art, made beyond the reach of the academy and the market, by people who never trained, never networked, and mostly never imagined an audience at all. The critic Roger Cardinal coined the English term in 1972, and people have argued about it ever since.
Kusama sat directly on top of the argument.
The insider’s CV
She trained for a year in traditional nihonga painting in Kyoto, from 1948, and hated it. She wrote to Georgia O’Keeffe for advice, got a reply, and used it as a springboard to New York in 1958. She put herself at the centre of the avant-garde alongside Warhol, Judd and Oldenburg. At the 1966 Venice Biennale she laid hundreds of mirrored spheres across the lawn outside the Italian pavilion, stood among them in a golden kimono, and sold them to passers-by for 1,200 lire, about two dollars each, until the organisers stopped her: a protest about art as merchandise, staged with a showman’s instinct for the front page.
In 1993 she was back at Venice on the official invitation that had never come, representing Japan in a mirrored room of pumpkins. Then came the mega-galleries, the Louis Vuitton collaborations, a museum in Tokyo with her name over the door, and auction totals that made her the world’s top-selling female artist.
Where the work came from
And yet. Strip away the CV and look at the source.
As a child in Matsumoto she began hallucinating. A pattern of red flowers on a tablecloth that spread across the room, her body, the whole universe. Fields of dots. Flowers that spoke to her. Her mother tore up her drawings. Painting was never a career move so much as a survival mechanism, a way of pinning the visions down before they pinned her.
The nets, the dots, the endless accumulation, the mirror rooms that dissolve you into infinity: all of it is obsession turned into method, repetition as a way of staying alive. She said, plainly and more than once, that art was what kept her here.
We hear a version of that often, from self-taught artists who make work because making it holds the day together. Nobody calls Kusama an outsider now. They call her a genius. The making was the same.
New York gave her the outline of fame but not its substance. In 1963 she showed a couch covered in sewn phallic protrusions; Claes Oldenburg, who had not worked in soft sculpture before, was showing sewn soft sculpture within months, and his wife apologised to her at the exhibition. She showed a boat with photographs papering the walls around it; Warhol later covered a gallery in repeated photographic wallpaper. Art historians are careful with the word for this, and so are we: influence ran one way, and the credit ran the other. In 1977 she checked herself into a Tokyo psychiatric hospital and stayed for the rest of her life.
She did not hide it, and this matters. She wrote and spoke about her hallucinations and her mental health for fifty years, at a time when almost nobody in her position did. She turned the thing that was supposed to disqualify her into the reason the work exists.
So, was Yayoi Kusama an outsider artist?
Who am I to say? This is proof of how flimsy the border is, but you know yourself if you fit the category of outsider artist. Some people don’t like the term even if they perhaps fit its characteristics.
The compulsive mark-making that gets filed under outsider when it comes from an unknown hand in a day centre gets called genius once the market catches up. Kusama spent decades on the wrong side of every door that mattered, as a woman, as a Japanese artist in a white American scene, as someone living with mental illness. Later the same art world made room for her. The work was always the same work.
That is the lesson we hold onto at BRUT, and it is not an abstract one. It is the difference between work that gets seen and work that stays in a folder because nobody ever asked. Outsider describes a circumstance, not a level of worth, and the wall between inside and outside turns out to be a polka dot pattern: porous, repeating, nothing solid about it at all.
Kusama’s dots were always saying this. Our earth is only one polka dot among a million stars, she wrote. Self-obliteration, she called it. The self dissolving into everything else, with no hierarchy left standing.
She painted until the end
Kusama worked to her final days on the flowers, eyes and pumpkins of her late painting cycles, still turning private compulsion into rooms that stopped people in their tracks. Japan awarded her the Order of Culture, its highest honour for the arts. She spoke often, and without much modesty, about fighting for her art to the last and wanting it to outlive her.
They will. There is no better argument for what art is actually for, and no better patron saint for a studio like ours: the artist who was kept outside for decades, and who kept painting until the walls came down.
Yayoi Kusama: quick answers
How did Yayoi Kusama die?
Her studio announced on 27 August 2026 that she had died on 14 August at a hospital in Tokyo, aged 97. The statement gave no cause of death.
Why did Yayoi Kusama live in a psychiatric hospital?
She admitted herself voluntarily in 1977, a few years after returning from New York, and chose to stay for nearly fifty years, working daily from a studio nearby. She was open throughout her life about her hallucinations and her mental health.
Was Yayoi Kusama self-taught?
No. She studied traditional nihonga painting in Kyoto for a year from 1948, although she rejected the style almost immediately.
Was Yayoi Kusama an outsider artist?
Not by the strict definition: she trained formally and became the art world’s most celebrated figure. But her work came from hallucination and compulsion, and she lived by choice in a psychiatric institution, which makes her the great border case. Many artists who fit the characteristics dislike the label, and that is their call to make.
What was Yayoi Kusama most famous for?
Polka dots, pumpkins, her Infinity Net paintings and the Infinity Mirror Rooms that drew record crowds to museums around the world.
What is outsider art?
Art made by self-taught creators working outside the professional art world, often in institutions or on society’s margins. The term translates Jean Dubuffet’s art brut and was coined in English by Roger Cardinal in 1972.
