Famed avant-garde artist Yayoi Kusama unveiled her latest works, made of huge balloons, before they are displayed this weekend at an art festival in Tokyo's Roppongi district.

"Yayoi-chan," a 10-meter-tall balloon girl, and "Ring-Ring," a 4-meter-tall balloon dog, both decorated with her signature polka dots motif, will be shown at the Roppongi Hills complex during Roppongi Art Night on Saturday and Sunday.

The arts fest also includes events at other area sites, including Tokyo Midtown and the National Art Center, Tokyo.

According to Kusama, "Yayoi-chan" embodies both her childhood and her current life, and symbolizes peace and hope. "Ring-Ring" is the pet dog of "Yayoi-chan."

Kusama gave a speech in front of the two works Thursday, saying she has long believed in the power of love and art.
