Japanese artist Yayoi Kusama, best known for her colorful, polka-dot-covered artwork and sculptures, has died.

She was 97.

Kusama's official website announced her death on Thursday, saying in a statement that the artist had died in a Tokyo hospital on August 14.

It did not specify a cause of death.

"She continued to paint until her final days, never setting aside her brush, and continued exploration of forever love and eternal soul," the statement read.

Born in Matsumoto, Japan, in 1929, Kusama experienced visions and hallucinations from a young age that would later become central to her art .

Over the years, Kusama's body of work grew to include the Infinity Mirror Rooms and pumpkin sculptures that helped make her one of the world's most recognizable contemporary artists.

Kusama began exhibiting her work in Japan in the '50s, before moving to New York in 1957, where she quickly became part of the city's avant-garde scene .

There, at her first solo exhibition, Kusama debuted a series of paintings that would later be known as "Infinity Nets." In a 1961 article, Kusama described working "as much as fifty to sixty hours at a stretch," becoming "under the spell of the accumulation and repetition" in the "nets" of her art, per M+ Magazine , the digital publication of Hong Kong's M+ contemporary-art museum.

Kusama's tireless approach to making art continued throughout her life.
