Mito Citizens Gymnasium, Indoor sports complex in Mito, Japan

The Mito Citizens Gymnasium is an indoor sports complex with multiple courts designed for basketball, volleyball, and various athletic events throughout the year. The facility offers modern equipment, dedicated training areas, and spaces for both competitive athletes and recreational users.

The gymnasium was completed on 31 March 1974 in Aoyagi Park and hosted the gymnastics competitions of the 1974 National Sports Festival. Since 1 April 2006 the Mito City Sports Promotion Association has run it as designated manager. In 2019 the Ririi Bunka Gakuen school corporation acquired the naming rights, and from 1 April 2019 the hall is called Lily Arena Mito.

The gymnasium serves as a gathering place where local schools, sports clubs, and community organizations regularly hold their training sessions and competitions. People from Mito come together here to practice and participate in events throughout the year.

The gymnasium is located in Aoyagi Park, making it easy to find and access for visitors coming to train or attend events. Since it is a busy venue, checking the schedule beforehand helps avoid crowded times and ensures you can enjoy the facilities.

The arena hosted two world flyweight title fights: on 12 May 1981 Masao Ohba's successor at flyweight, Antonio Avelar of Mexico, fought here, and on 29 July 1990 the WBA flyweight title bout between Lee Yul-woo of South Korea and Leopard Tamakuma took place. It was also the venue for the national junior high school wrestling championships from 2016 to 2018.
