Saitama City is moving forward with the relocation and development of its new city hall, aimed at providing sustainable resident services and serving as a hub for dynamic urban management for the designated city. Following the start of the basic design in November 2024 and incorporating public feedback, the design was completed in April 2026.
### 1. Overview of the Basic Design
The new city hall will consist of three buildings: the Administrative Wing, the Assembly Wing, and the Central Plaza Wing. A pedestrian deck will be extended from Saitama Shintoshin Station to improve accessibility and create a barrier-free environment with no stairs or steps from the station.
- **Location:** 1-603-1 Kita-fukuro-cho, Omiya-ku, Saitama City, and surroundings.
- **Site Area:** Approx. 15,000 square meters.
- **Total Floor Area:** Approx. 64,000 square meters.
- **Floors:** 1 underground, 19 above ground.
- **Construction Cost:** Approx. 70.5 billion yen (including demolition, as of April 2026).
### 2. Key Points of the Basic Design
**(1) A Disaster Resilience Hub to Protect Citizens**
The Central Plaza will serve as a temporary stay area during the initial phase of a disaster and later as a site for emergency recovery activities. The building uses a seismic isolation structure for high safety. It includes multi-purpose spaces for business continuity and a helipad to strengthen emergency response. Emergency power and water supply systems will enable up to 7 days of operations.
**(2) A Hub for Citizen Gathering and Relaxation**
The Central Plaza will be an indoor space comfortable year-round, equipped with a large screen and movable seating for diverse events. It connects to the lush Outer Plaza and Terrace Plaza, creating spaces for daily relaxation and vibrant community events.
**(3) A Green and Decarbonized City Hall**
The project includes vertical greening to form a green network connecting to nearby parks. It aims for ZEB Ready certification by reducing environmental impact through natural ventilation. Next-generation solar cells and energy monitoring systems will also be installed.
**(4) High-Quality Administrative Services**
An integrated counter system will allow visitors easy access without security checks for basic services. The office space is designed to support flexible work styles, improving employee productivity and effectively responding to diverse citizen needs.
### 3. Schedule
The city aims for relocation and service commencement by fiscal 2031.
