Naon no Yaon

Created and "produced" by heavy metal band Show-Ya, performing artists and staff members are restricted to females, but attendance is open to everyone.

[a][2][3] 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.

[4] On the variety of participants, Terada explained that because there were not many all-female bands when the event was first started, idols, actresses and professional wrestlers took part in the past.

[5] The "naon" in the title was devised by reversing the syllables of "onna", the Japanese word for "woman", while "yaon" is a commonly used abbreviation of the venue's name.

[7][8] Ann Lewis, Nokko, and Minako Honda are some of the other musical acts that performed during the original run of the festival.

Attended by an audience of 3,000, the event lasted 5 hours and featured 61 people in total, all of whom appeared on stage to perform "Toriaezu Rock 'n' Roll" by Carmen Maki & Oz as the final song.

[30] In 2011, Show-Ya produced the Muon no Yaon (MUONのYAON) charity event at Hibiya Open-Air Concert Hall on May 7, where admission was free but donations encouraged to aid recovery from the 2011 Tōhoku earthquake and tsunami.
