Gate City Ohsaki
This is a large complex linked directly to the southern ticket gate of JR Osaki Station. It features a zone of restaurants and shops spread between the basement level and the third floor, enveloped by the East Tower and the West Tower. The structure from the basement to the third floor is designed with an atrium, and events such as concerts frequently take place in the square.
It's super convenient since it's directly connected to Osaki Station!
