Naon no Yaon
music festival in Tokyo, Japan

Naon no Yaon (Japanese: NAONのYAON) is an annual all-female music festival held at Hibiya Open-Air Concert Hall in Tokyo, Japan's Hibiya Park. Created and "produced" by heavy metal band Show-Ya, performing artists and staff members are restricted to females, but attendance is open to everyone.
History
Naon no Yaon is produced by all-female band Show-Ya and each member recommends acts and helps decide the performers, but lead singer Keiko Terada is the main force behind the festival. She was inspired by The Alfee's performance to 100,000 people on the Tokyo waterfront in 1986. After Terada explained her thoughts on a radio program, Show-Ya's record company and agency got onboard with the idea. With the Equal Employment Opportunity Law enacted just that same year, the music industry was still male-dominated and all-female bands were rare. Whenever Show-Ya appeared on a music television show, they would ask fellow female talents who were there at the same time if they would be interested in participating in an all-female concert. Thus, the early Naon no Yaon events featured a wide variety of participants, including idols, actresses and professional wrestlers. However, in 2014 Terada said the number of female bands had increased significantly and that they had to put limits on the number of solo artists and bands they can have.
The first Naon no Yaon festival was held at Hibiya Open-Air Concert Hall (Hibiya Yagai Ongakudō) in Tokyo on September 20, 1987.
