BASEGATE Yokohama Kannai to Open March 2026 on Former Yokohama City Hall Site
The redevelopment project on the former Yokohama City Hall site, located directly in front of JR Kannai Station, will open on March 19, 2026, under the name BASEGATE Yokohama Kannai.
The project consists of a tower featuring office and retail space—set to include the shared office “co-ba kannai/yokohama (tentative name)”—and the repurposed former city hall administrative building, which will be converted into the hotel OMO7 Yokohama by Hoshino Resorts. A pedestrian deck along Minato Odori will directly connect the complex to Yokohama Stadium, aiming to enhance vibrancy in the station plaza area.
