The Tokyo Bay Cross-Sea Highway is branched from the Capital Expressway Wangan Line in Kawasaki City, and links to Kisarazu City, Chiba Prefecture with the Tateyama Expressway, with a total length of 15.1 kilometers, four lanes on the whole line, and a design speed of 80km/h. The cross-sea highway is divided into two main parts. The Kawasaki side is a 9.6-kilometer-long undersea tunnel, while the Kisarazu side is a 4.4-kilometer cross-sea bridge. In the middle is an artificial island that combines restaurants and shopping to connect the undersea tunnel and the sea. The bridge doubles as an emergency escape. The sprawling artificial island, nicknamed "Sea Firefly" rather romantically, functions primarily as a driver's rest area, with shops, restaurants and an observation deck for views of Tokyo Bay. The sea firefly is a kind of crustacean in the sea. It is very smiling, but it emits a blue light at night, just like a firefly, very beautiful. The name "Sea Firefly" has won the love of most people, and it has become another name for this artificial island. Firefly Island in the sea has 5 floors. The facilities in the station are quite complete. There are also many restaurants. You can enjoy the night view of Tokyo Bay from the sea, which is very beautiful.
