A service area floating on the sea! Umihotaru!

I went to Umihotaru, a service area floating on the sea! When you board a plane from Haneda Airport, you can see the view from the window, but there's also a mysterious building floating above the sea that looks like a car is being sucked in! It's so mysterious and intriguing, I've been curious about it. It's a service area on the Aqua Line, which connects Chiba and Tokyo in Tokyo Bay! So I went! When I arrived, I was surrounded by the sea! (Of course (lol)) I could even vaguely see Haneda Airport! Planes flying in and out of Haneda Airport were flying by, making it a must-see spot for airplane lovers. I only have photos of the view, but there were also a huge selection of souvenir shops, a food area, vending machines, and even a convenience store!
