If you're driving around Okinawa, Kaichu Road is definitely a worthwhile route to include! Although its name means “undersea road,” it isn't actually underwater. It's a road over the sea connecting Okinawa's main island with the Katsuren Peninsula and the Henza Island area, with endless blue ocean views along the way.
What I liked most was having the ocean on both sides while driving. When the weather is good, the water is a beautiful blue-green color, and the view is very open. With no tall buildings blocking the scenery, the entire drive feels especially pleasant and has Okinawa's distinctive resort atmosphere.
You can also find a place to stop along the way to take photos and look at the ocean. Standing by the sea with the wind blowing really makes you want to slow down. Compared with simply rushing from one attraction to another, I think a trip where you enjoy the scenery along the way actually feels more like traveling.
