Qiball is a public-private complex located in Chuo Ward, Chiba City, Chiba Prefecture. The building brings together facilities focused on children, parenting support, daily life, industry, health, and public administration.
The complex is home to the Chuo Ward Office, Chiba City Science Museum, Children’s Exchange Center, Child-Rearing Support Center, and Chuo Health and Welfare Center, along with commercial facilities and other services.
Qiball was developed as part of the Chiba Chuo Sixth District Type 1 Urban Redevelopment Project, an initiative designed to revitalize the commercial functions of central Chiba City, which had declined following the collapse of Japan’s bubble economy.
The site had previously been occupied by facilities including the Chiba City Hall Chuo Branch Office, formerly the location of Ogiya Jusco, as well as Chiba Fudoson Komyoji Temple.
The commercial section of Qiball opened first on September 1, 2007. The entire complex, including its public facilities, opened on October 20, 2007.
Qiball is a 15-story building above one basement level. Different types of facilities are arranged throughout the building:
The building features an open atrium with elevators providing direct access to the various floors. One of its most distinctive features is the spherical planetarium located within the complex.
The name “Qiball” was selected through a vote by Chiba City residents. It expresses the idea of a “ball of hope.” The letter “Q” also serves as a symbolic reference to the spherical planetarium inside the building.
The Chiba City Science Museum is an interactive science museum built around the concept of “People Take Center Stage.” It offers visitors opportunities to experience science through hands-on exhibits and activities rather than simply viewing displays.
Various programs are held throughout the year, particularly on weekends, including workshops, science craft activities, and special programs such as Plus Science.
The museum is divided into several themed exhibition areas:
The planetarium at Chiba City Science Museum features a 23-meter-diameter dome screen and can project more than 10 million stars.
The system can reproduce countless faint stars, including stars that create the appearance of the Milky Way, providing visitors with an immersive experience of the night sky and universe.
The Chiba City Children’s Exchange Center provides a safe place where children can play and interact with others after school on weekdays and during holidays.
Admission is free, and the facility serves as a community space where local children can spend time together. It is operated under Japan’s designated management system by the Chiba Mirai Children’s Project Consortium (Actio).
The Chiba City Child-Rearing Support Center is a support facility for preschool children and their parents or guardians.
It provides spaces where parents and children can play together, access information about childcare, and seek advice about parenting and family-related concerns. Admission is free, and the facility is operated by the Chiba City Private Nursery School Council under a designated management system.
The Chiba City Chuo Health and Welfare Center serves as a base for health and welfare services in Chuo Ward.
The 12th floor contains examination and health-check facilities, while the 13th and 14th floors handle various applications and administrative procedures. Residents can receive health consultations and access a range of welfare services here.
The Chuo Ward Office occupies the 11th floor of Qiball and provides a variety of administrative services related to residents’ welfare and health.
Qiball also contains commercial and service facilities, including Daiei Gourmet City, the Chiba District Office of the Japan Legal Support Center (Houterasu), and a multi-level self-parking facility.
The Chiba City Business Support Center was formerly located on the 13th through 15th floors of Qiball. In 2019, it moved to Chiba Twin Building No. 2.
The center provides consultation and support for local businesses and offers assistance to people interested in starting their own businesses.
