"I love the view from directly under the Tokyo Bay Aqua-Line bridge. It's just the sea, the sky, and the human-made bridge—the powerful, unique perspective is incredible."

"This is a toll-free highway and a bypass that acts as a shortcut over Tokyo Bay.
Because it's far from the coast, the night view from the bridge and Umihotaru PA is dark and not very good. The daytime view is recommended."
Tsuyoshi N
"I often use this station. The sunset before entering the Aqua Line is beautiful, and the sea is silvery."
