Venue: Hibiya Open-Air Concert Hall
Town: Hibiya Park, JP

The Hibiya Open-Air Concert Hall (Japanese: 日比谷野外音楽堂, Hepburn: Hibiya Yagai Ongakudō) is an outdoor music venue in Hibiya Park, located in Chiyoda, Tokyo, Japan. Owned and managed by the Tokyo Metropolitan Government, music events are limited to weekends and holidays between April and October out of consideration for the surrounding urban area. The venue closed for extensive rebuilding on October 1, 2025. There are actually two concert halls - the smaller was erected during the Meiji era, and the larger was first built in the Taishō era. The larger venue is colloquially abbreviated to Yaon (野音). As the site of the first full-scale rock music concert in Japan, it is also referred to as the "Holy Land of Rock" (ロックの聖地, Rokku no Seichi). Hibiya Park, where the concert hall resides, was built in 1903 as Japan's first Western-style park. It was designed to incorporate three elements: Western flowers, Western food, and Western music. The last was achieved with the creation of the smaller music hall in 1905. It could accommodate about 1,000 people, but due to many Tokyo residents flocking to it to hear Western classical music, a larger facility that could accommodate more people was needed. The large music hall, colloquially known as Yaon, was first built in July 1923. Two months later, the smaller venue collapsed during the 1923 Great Kantō earthquake, but was rebuilt. Initially, Yaon was also used for other types of entertainment, such as boxing matches. Due to a lack of safety laws at the time, there were no capacity restrictions, and the venue is said to have attracted 5,000 to 10,000 people. The large venue was closed in 1943 due to the Pacific War, and when the war ended, it was then under the control of the Supreme Commander for the Allied Powers for six years. When it was returned to Japan, the venue was rebuilt in August 1954. Between 1982 and August 1983 it was completely rebuilt again, as was the small hall. At this point, the small hall had 1,000 seats, while t
