Nonagenarian Japanese artist is simultaneously one of the most famous
and most mysterious artists on the planet. A wild child of the 1950s and
1960s, she emerged out of the international Fluxus movement to launch
naked happenings in New York and went on to become a doyenne of that
city's counter-cultural scene. In the early 1970s, she returned to Japan
and by 1977 had checked herself in to a psychiatric hospital which has
remained her home to this day. But, though she was removed from the
world, she was definitely not in retirement. Her love and belief in the
polka dot has given birth to some of the most surprising and inspiring
installations and paintings of the last four decades - and made her
exhibitions the most visited of any single living artist.
